You know...

bbl to receiver: 1"x 16tpi, inch and metric; Israeli, metric thread, chase with 1"x16 die.

cross screw for mag release and BHO. 10/32

pistol grip stud/nut 1/4x28 tpi (metric)

inner threaded hole on buttstock double threaded nut (the one that retains the recoil springs) 1/4x28 tpi (all types)

frame lock lever retaining screw (the little one in the back that keeps the lever in) 10/32

I think this would be a good thing to have here for reference in case some of us who know can help someone save something they have previously considered trashed. And to keep it permanently posted here. Could save some of us a lot of aggravation. D.

I lost the set screw to the front sight on my Aussy (inch) L1A1 (kit). Does anyone know what size/threads it is?
I was thinking of heading down to the hardware store and seeing if I could find something close enough to work.
TIA

I hate to ask a stupid question but why are all the thread designations I have seen English, or SAE, designations, even on the Metric parts?

I would have thought that any rifle manufactured for a country that used a Metric standard would use true Metric threads. Are folks just using the closest English thread that can be made to fit? Were all rifles actually made with English threads?

Thanks for any info.

Sorry, my English heritage coming through. In the days before SAE was a force for standardization, I think they were commonly referred to in some parts of the world as English threads to distinguish them from Metric threads. That may have been in the days of the Whitworth thread though.

Actually, I think the correct designation now is Unified threads.

Interesting thread on threads eh?

I wasn't trying to SCREW anyone up, but since we were TAPPED to provide input, it was an opportunity to DIE for. We should all PITCH our best info so we can get to the ROOT of the matter. We must remain UNIFIED if we want to hold things together.

This may end up CROSS-THREADED on the humour board. Just so it isn't STRIPPED completely.

This thread was ROLLED not CUT.

Ironwood or original issue? The new US made wood grips use a different thread on the screw than the real deal grip.

I believe it to be a 1/4" NF 24. Might want a second opinion on that though, I can't find my original screw. That and I don't have a tap to run through the grip or a die to make a bolt to test with. I do know the Ironwood ones are a 1/4" NC 20. If nothing else take the grip to the hardware store and test and try.

If your talking about the screw on the bottom of a L1A1 wooden grip that holds on the the popcycle stick it's a #8-36 SAE Screw!

Hmm... I believe historically speaking, the English standardized the measurement system which we first used in the USA, based on Imperial English measurements (inches feet etc).

I believe this first standard was developed by Sir Whitworth, became the British Standard Whitworth (BSW), which evolved into British Standard Fine (BSF). Then an American devloped a modified version which was adopted by the U.S. Society of Automotive Engineers (SAE). And then after WWII, all us proper English speaking allies (US, England, Canada, Australia) got together and mutually adopted Unified National Fine (UNF), which I believe the FAL uses. We should note that most of the FAL threads, while Imperial or SAE in standard, are not the commonly found SAE National Fine (NF) and Course (NC) thread pitches, but are generally much finer.

I'd call it an English standard, 'cause it evloved from an English measurement system, and an English thread Standard, but most importantly of all, becuase the other standard used in the world was developed by the French.

Hail Britannia!!!!!!

L1A1 Pistol Grip Screw is a 1/4-28 slotted round head screw 1-1/4" long and uses a lock washer.
-------------

hex/allen head screw is also correct. Designation is UNF2A 1/4"x1-1/4". The washer is replaced with "Washer, lock, steel, flat, internal teeth, 1/4" ID x15/32 OD x .026" and goes between the head and the other washer - BA steel #0

inch but screws are 2.5" for extra Long and Long (EL, L) 2" for medium (M), and 1.5" for short (S)

angle of commonwealth front sight is 5 degrees forward

If Ironwood L1A1 then the size is 1/4" x 20 1 1/4"

Ironwood handguards use a different than original screw also, but I don't remember the size.

Rear sight windage screws for both Metric and L1 are 8/36, not 8/40

Co incidentally, the same as AR15 front sight. D.

I think the metric designation comes from the fact that the dimensions on the print for the receiver are all metric. however
I have always thought it strange that all the threads are english?

The pistol grip stud thread and the internal thread on the return spring tube nut (for the screw that holds the butt plate on the wooden stock) on the G1 lower I got from Tapco is 6x1mm. Six mm diameter by 1.0mm thread pitch.
A 1/4-28 UNF nut will screw onto a 6mm stud or screw but it will be quite sloppy.
A 1/4-28 UNF screw will NOT go into a 6mm nut.
The outside diameter of the 6mm fastener is about .015 inch smaller than the 1/4 inch fastener.
Thanks.

Either you have an anomoly or you are measuring incorrectly. the correct size for both on a G1 is 1/4x28 and I have 50 of them here of which I spot-checked ten. all are eaxactly 1/4x28, although a few are dented so threads need to be chased for smooth joining.

Gunplumber you are correct. I got hold of a set of thread pitch gauges and checked again and the threads are 1/4-28.

How about the threads on the OD of the return-spring tube where it mounts to the lower? I'm assuming this is the same thread as the opposite (recoil pad) end of the tube, but have not disassembled to check.

Thanks!

Recoil spring tube male thread is also 17/32x36. The internal, female thread on a recoil spring tube (and the male thread on the plug) is smalle - 15/32x36.

How about L1A1 Muzzle Threads?
I saw Metric above, but no mention of inch.

I know it's probably listed somewhere, but I haven't found it yet!
Itwould be useful to have it on this thread.

Anybody have the para bolt thread pitch? The bolt that holds the hinge assembly to the lower? It looks like 5/8 inch by 36 tpi. I need to chase some threads. Thanks,

There are two, which is the cause for some confusion. The smaller one is a para lower made from a standard lower. That is, 17/32x36, which is the same as a recoil spring tube male thread. The other is a dedicated para lower and is 9/16x32.

They are both slit in a cross and threaded internally for a screw (#12x32, same as a metric front sight) with a tapered head. The tapered head will expand the threads and lock it in place (days before locktite?). They come in both steel and aluminum for both sizes.

This makes removal extremely difficult, and I find a high percentage seized. I can usually remove them by drilling a hole from the front, Then using a standard butstock screw driver, but since its very difficult to get the lower fixtured without crushing anything, I usually have to replace the para bolt. I turn them out of cut-off barrel sections - like 10/22 heavy barrels at .920 OD

Not the answer I was hoping for, but thank you for the response.
I wanted to make a different length gas tube and don't have threading capability on my lathe.
Guess I will have to resort to the bandsaw and MIG.

Unless I've missed it I haven't seen the threads for the gas regulator on here. I actually need what they are for the gas block where the regulator screws on. Anyone?

Thanks,
Aaron

If all the fasteners and the barrel are threaded in SAE format why the heck is the gun a "metric" FAL ? Does that not seem a bit silly?

I would find this helpful, too.

Hi Guys: Just bought a muzzle break for my L1A1. Was advised that it was THE correct one for my rifle but that they were not that common so my plan to simply slot the tube, drill the major diameter a little deeper and tap the pin hole to pull the sleeve tight may not be the best choice of action. My next plan was to buy the appropriate die and thread the muzzle using my angle plate V slot on my drill press and use the spindle to guide the die straight on to th barrel. The barrel OD. is 0.685, if the thread is actually a 9/16 x 24 , then I must assume that the barrel must be removed and turned to the major OD. for 9/16 (0.5325 dia.) x 24 (preferably between centers)and threaded. I will need the rest of the specs (pin size, thread length, tolerances,flat at the bottom of the minor OD, depth, fit, I assume that these are 60 degree V threads), instructions and access to disassembly, etc.) and access to a lathe.
In addition all of these 0/32 threads have me puzzled as I have been a machinist for 25 plus years and have never heard of them. It is a very very BIGGGG world. Please advise.

Later

Merrden
