Common thread dimensions

drilling: (HAAS University videos)

drill bits: at least 2 diameters of flute length outside of hole

"stub" and "jobber" lengths, use shortest that does the job due to rigidity

top angle: 118 (general purpose HS for mild steel, Al...) or 135 deg (for harder materials)

helix angle: usually 30 deg; down to 10 deg (harder to break, high-torq) for special apps - harder steels, Al alloys; up to 40 deg for difficult materias like stainless (low torque)

self-center point - many cobalt, most carbide, few plain as it is harder to grind that (so they "walk" and need spot drilling)

steel drills just 2-3 times their diameter
carbide up to 5 times
then it's peck-drill (increases edge wear as drilling is started more times)

deep drills: pilot hole with stup hole to 1.5 d, then low rpm to insert to hole and then go full speed

slow to 50% rpm and feed rate for last 2mm of hole as thin material won't conduct away enough heat and overheats, work hardens, wears tool

unthreaded part of the bolt = "grip"
should not extend more than 2 threads into the hole, otherwise thread edges act as reamers on vibrating parts

countersink angles

https://ruko.de/en/blog/structure-and-application-of-countersinks
60deg   deburring; on some larger metric (over M20; M22 and over); some rivets
70deg   some rivets
75deg   rivet heads (less common? not in wikipedia article)
78deg   aircraft rivets AN425
80deg   (not in wikipedia) screw countersinks, DIN standard
82deg   common for screws, US standard, common on Unified Thread screws
90deg   common for screws, metric/ISO standard, common on metric screws; US wood screws (82deg for metal)?
100deg  on aircraft/AN/milspec rivets and structural screws, AN426/427; with thin-skinned missiles and aircraft; often "reduced head" (smaller head dia)
110deg  uncommon
120deg  sheetmetal rivets, flat-head sunk sheetmetal screws, some small-head screws
156deg  rivets for honeycomb composites
180deg  flat; counterboring

wafer heads: 70deg center part, 16deg topmost part; preferred for self-tapping screws
bugle heads: concave shape, for drywall/plasterboard

 multiple standards exist, due to import of tech from multiple countries
 Whitworth primarily in Navy, railways, private factories - modeled after British tech
 metric primarily in the Army (Sasaki 1949) - Army follows Germany/France
 1924, JES13 metric standard established
 1927, JES68 Whitworth standard established
 metric for automobile, aircraft
 metric for diameters below 9mm
 Whitworth for all other uses
 1965, standardized to ISO

 1841, Whitworth begins standardization in UK, spreads to Europe with British machines
 1864, W. Sellers creates Sellers Thread, adopted as US Standard Screw thread in 1868, later Americal National Thread
 Sellers thread spreads through France, becomes Metric Thread
 1957, Sellers standardized by ISO, Whitworth de facto abolished

UK

 early british M6-1,0 or M8-1,25 standard practice manufactured nut will NOT fit a modern M6 or M8 with the same pitch.
Standard practice in this country was to use an increased core diameter, which in its turn gives a larger radius
at the minor diameter on the screw, and a bigger minor diameter at the nut.

BA threads:
https://www.fastenerdata.co.uk/ba-thread
BA threads are still common in some applications, certain types of fine machinery, such as moving-coil meters and clocks,
tend to have BA threads wherever they are manufactured. BA sizes were also used extensively in aircraft, especially those
manufactured in the United Kingdom. BA sizing is still used in railway signalling, mainly for the termination
of electrical equipment and cabling.

 .980"-12 tpi fits Small Ring Mauser (plug tap cuts full-depth threads on small ring 98s with internal shoulders)
 1.00"-16 tpi fits FN-FAL; 1.10"-12 tpi fits Large Ring Mauser
 11⁄16"-16 tpi fits Remington 700 and XP-100
 1.055"-20 tpi fits Savage 110/112.

two most important threads on the AR-15/M16 receivers:
 1.250"-18 tpi - Corrects out of spec or cross-threaded upper receivers and barrel nuts.
 1-3/16"-16 tpi - Makes receiver extension (recoil buffer) tube and lower receiver threads uniform for easier installation.

Semi-auto pistol custom compensators for reduced recoil and better control:
 Unthreaded comps should be drilled with 3-5/64" HSS drill then reamed to .551" before threading with either tap.
 Turn barrels to approximately .002" smaller than thread diameter.
 .575"-40 thread matches most commercial, tapered-sleeve or integral, cone-style comps.
 .581"-40 thread is same as used on Wilson, Brown and Storm Lake Machine barrels and bushing style comps.
 .685"-40 thread is used to fit compensators to threaded Bull and Hybrid barrels.

M10x1            German WW2 grenade M39, fuze BZE 39


"The fuze is what gives it away as a novelty grenade. The fuze on your grenade is either an M213 or an M228 fuze
 (the crooked spoon and the notch for the "jungle clip" tell us this.) A real MKII uses an M10 series fuze (i.e., M10, M10A1, M10A2, M10A3)
 or an M6 series fuze. The M21 (a practice grenade version of the MKII) practice grenade uses the M205 practice fuze.
 You can also verify this (i.e, your grenade being a novlety vs a real one) if you have access to either a MKII or an M21.
 The threads on the M10 series, M6 series, and M205 practice fuzes are the same and they are a different thread pitch than the M213 and M228 fuzes
 and they will not interchange. The M10/M6 fuzes will not fit the repro/novelty grenades."

27 pitch is used almost exclusively for small tapered pipe threads, some mike stands, and the straight brass pipe thread
used in lighting fixtures. If the engagement is short and the thread is a set used like in a light fixture where mechanical
strength is of little consequence you can use 28 threads per inch and bore or thread for clearance. It won;t fit right but it will do the job.

tire designs:

liquid ballast can be added to tires to increase weight, lower center of gravity of tractors [ref]
(water (freezes), calcium chloride (corrosive but dense and cheap), beet juice (expensive), windshield washer fluid (not dense), antifreeze (expensive)
usually about 75% fill

CO2 is highly soluble in butyl rubber, tire inflated with a CO2 canister will quickly lose pressure
air-inflated car tires lose about 1 psi (6.7kPa) per month, more at hot days
weight capacity is pressure times volume

M20x2 (on some lampshades)

3/8 IPS: This was the size of the outlets for gas lighting; the system of sizes used for the pipes that brought gas to gas lights was adopted for electric lights. In older ceiling fixtures (the outlet box is perfectly round instead of square) the light is attached to a 3/8 IP stud, just as a gas light was. Today an adapter, called a “hickey,” is used to get from the 3/8 IP stud to the fixture's 1/8 IP.

threads in wood - 60deg V-thread dimensions for wood

60deg V usual off the shelf
90deg V traditional, stronger (use declined in 19th century)

https://www.lakeerietoolworks.com/collections/wooden-vise-screw-kits/products/la-forge-royale-miter-jack-hard-maple-screw-and-nut
90 degree (flatter) threads are less likely to chip on smaller threaded vises
and are the type that we use on our Moxon screws as well.  60 degree threads (steeper)
work better for larger screws with lower turns per inch (bigger threads) as they have
more surface area for the screw and nut to engage.

artillery fuzes, US Civil War

https://etd.ohiolink.edu/!etd.send_file?accession=osu1131732518&disposition=inline
Bormann Fuze had 12 threads per inch
many of the Schenkl Fuzes had 10 threads per inch
British fuzes had 14 threads per inch

Prior to the war, the standard number of threads per inch for the Bormann,
Navy Watercap, and paper fuze adaptors was 12 threads per inch.
Some inventors, such as Robert Parrott and Benjamin Hotchkiss,
stayed with this standard. However, John Schenkl, George Ganster, and John
Absterdam used a different standard. Schenkl’s percussion fuze used 9, 10, or
12 threads per inch while his early combination fuze used 14 threads per inch.264
Ganster went to even finer threads and used 16 threads per inch on his fuze
while Absterdam used 11, 14, or 16 threads per inch.265 The problem was that
while the army’s and navy’s Ordnance Departments had specifications for most
of the equipment used by the military, no written record has been found on
specifications for mechanical fuzes.

It is interesting to note that 12 threads per inch remained a standard for the US Military for a
number of years. Today, while 12 threads per inch is still widely used, some of the newer fuzes
have a different number of threads per inch. One reason for the different number of threads per
inch is the desire not to have certain fuzes mixed up with each other. This information was
provided in an e-mail message from Patrick Owens, Historian, ARDEC Historical Office and
Museum.

Watchmaker's screwplates are often found bearing makes names such as Martin, Martin et fils or Perrelet and Martin. There does not seem to be much information around on what threads these plates actually cut. Hence I have collected as much as I can find.
L Latard (also called Perrelet and Martin), finer
B Bourgeaux, more coarse
G Gauche (Left Handed)
S

The number at the top of the plate is the number of holes in the plate (typically 36, 30 or 24). Conventionally there are two holes for each thread size in the plate (in case one becomes blocked, by a workpiece breaking off when in the process of being tapped). Each hole is numbered in the series which runs from 0 to 21. Typical examples
24 plate    5 through 16
30 plate    4 through 18
36 plate    sizes 4 through 21

Bourgeaux thread:
Also known as Bourgeaux & Delamure.;
In the 19th century, a screw thread series used in Switzerland for manufacturing watches and clocks.
It was realized in screw plates made by Martin, Perrelet et Martin, or Martin Fils. 
Plates marked “B” are the bourgeaux series. A “G” on the plate indicates left-hand threads.

projectile/bullet lead alloys

Pb70Sb30         master alloy to add antimony, 745'F melting
Pb95Sn5          20-to-1, Brinell approx. 10, popular for use in Cowboy Action Shooting and standard blackpowder cartridges such as the 45-70 Government
Pb94Sn6          16-to-1, Brinell approx. 11, popular for use in Cowboy Action Shooting and standard blackpowder cartridges
Pb96Sn4          25-to-1, Brinell approx. 9, popular for use in Cowboy Action Shooting and standard blackpowder cartridges such as the 45-70 Government
Pb97.5Sn2.5      40-to-1, Brinell approx. 8.5, softer, consistent expansion and excellent weight retention at blackpowder velocities
Pb64.5Sb23Sn12.5 Brownells Foundry Bullet Casting Alloy
Pb92Sb6Sn2       Brownells Hardball Bullet Casting Alloy, Brinell approx. 16, modern version of the old Lyman #2,great for use in handgun bullets and many higher velocity rifle cartridges
Pb84Sb12Sn4      Brownells Linotype Bullet Casting Alloy, Brinell approx. 22, very hard alloy is ideal for higher velocity rifle bullets used when target shooting.
                 It's a bit too hard for silhouette shooting or hunting as the alloy tends to shatter on impact with metal plates of heavy bone.
                 If used with pure lead, a 1 to 1 blend with Linotype will produce a Hardball like alloy.
...for every 1% of tin in lead, Brinell hardness increases by 0.3

CGA Fitting Reference

A CGA fitting is the standardized system for the attachment of a compressed gas cylinder to the required regulator or transfer line.
Examples of CGA fittings would be:
CGA-580 for Non-flamable, Non-oxidizing gasses such as Nitrogen, Argon, or Helium.
CGA-590 is used for compressed air
CGA-326 is used for Nitrous Oxide.

CGA-540 for oxygen  - male on bottle
CGA 510 - propane, large industrial acetylene - female on bottle
CGA 300 - acetylene, large industrial, male on bottle
CGA 520 - acetylene, "B" (40 ft3) male on bottle
CGA 200 - acetylene, "MC" (10 ft3) male on bottle
CGA 580 - Ar, N2, He
CGA 350 - H2
CGA 320 - CO2, male on bottle

An opening with some very heavy coarse, weird thread in it known as the dreaded "buttress" thread: Doesn't fit any standard faucets or pumps.
Buttress threads are a holdover from the early days of plastic drums. Back then, it was difficult to precisely mold pipe threads directly into the drum.
NPS plugs would leak, cross thread, or strip out when you tightened them. The heavy, strong buttress thread solved the problem.
Today, plastic drum technology is vastly improved, and NPS plugs now perform just as well as buttress plugs.

The full set of diameters used by Canon (I think) is:
52mm - only used on a few lenses, mostly primes, Canon Used on the small primes, such as the 50mm 1.8 mark 1 and the 28mm 2.8, and on some earlier consumer/midrange zoom lenses.
58mm - very common on consumer level lenses, vast majority of Canon midrange zooms, Canon few midsize zooms L and non-L
67mm - only used on a few lenses
72mm - most common on mid-range lenses (gold ring), Canon large/mid zooms and few primes
77mm - most common on high-end lenses (red ring), Canon most common on larger L-series lenses
82mm - only used on the TSE-24mm mkII(?), but I think some Sigma lenses use it as well

self-tapping and thread-cutting screw point types

https://elginfasteners.com/resources/screw-point-types/
Type A    - tapping - coarsest - for thin metals (0.015..0.05", 0.38..1.27 mm), sheetmetal, resined plywood, asbestos; 60-deg; sharp point; not recommended for new designs
Type B    - tapping - coarse  - for thick metals (0.05..0.2", 1.27..5.1mm), sheetmetal, nonferrous castings, plastics, plywood; 60-deg; larger root dia, finer pitch
Type AB   - tapping - coarse  - type A tip with type B thread
Type TK   - drilling - type B thread with drilling tip
Type TA             - UNC
Type 1    - cutting - UNC/UNF - single flute, general use, UNC/UNF-compatible thread
Type 17   - cutting - coarsest? - for wood, special long sharp point, coarse thread
Type 23   - cutting - UNC/UNF - for metals, UNC/UNF compatible machine screw thread, good chip clearing and maximum thread cutting area
Type 25   - cutting - coarse  - similar to Type 23, with Type B thread
Type F    - cutting - UNC/UNF - machine screw thread, for heavy sheetmetal, aluminium, zinc, lead castings, cast iron, brass, plastic
Type C    - forming - UNC/UNF - coarse or fine machine screw thread, blunt tapered point, higher torque, heavy sheetmetal and die castings
Type CA   - forming - UNC/UNF - like Type C, with gimlet point; useful when holes in adjanced layers slightly misaligned
Tri-Round - forming - UNC     - mostly coarse machine screw threads, better forming than Type C, needs less torque
Lo-Driv   - forming - UNC     - mostly coarse machine screw threads, tapered end, low end load, low torque

PF - cutting - for plastic, 30-deg thin long threads, smallest minor diameter
HL - forming - for plastic, double-lead with high and low, sharp thin threads
PLAST 48/2 - - for plastic, 48-deg thin long threads, less stress on plastic than 60-deg thread, trilobular
PLAST 60/1 - - for plastic, 60-deg threads
