LEC I* Firing Pin Retaining Screw Replacement

Hello everyone,

I am new to this site and to Enfields in general with the NZ LEC 1* that I got just last month being the first one to make it into my collection. Very happy to finally get a rifle of this family, moreso one of these!

Now, straight to the issue that I have run into and apologies for the lengthy description. I didn't think to take pictures until the end. So, when I went to disassemble the bolt for cleaning I found that the retaining screw was bulging up on one side. This was the side more over the firing pin, which looked like it was probably tightened while the retaining screw was still in. This made the slot narrower and therefore too small for any flathead screwdriver that I have. My dad, who is more mechanically inclined than myself, offered to see if he could use a dremel to make the slot wide enough. He did so, but when we went to unscrew the retaining screw, the head snapped in half. :( This was a known risk and is shown in the following photo.

I know that it is hard to find parts for these guns, so I hoped that a replacement screw from a No.1 Mk.3 would work. I ordered a new reproduction and an original one from Numrich. The original one turned out to be too big in diameter, not even remotely close to being the right screw. The reproduction one was the correct diameter, albeit longer. When I tried to fit the screw it wouldn't even start going in. This was figured out after looking under a magnifying glass, seen here:

This is a comparison of the original screw (left) and the reproduction (right). Other than the obvious difference in length, there also appears to be a difference in the threads pitch. This is highlighted by the red arrows showing two points where the thread peaks touch on different sides.

This photo is just to better clarify which exact screw is being referred to so there is less chance of confusion. The hole on the bottom is the spot for the retaining screw.

I have a few questions related to how difficult it will be to get a correct replacement screw:

1. Are there any screws for sale that I have missed in my searching or aren't directly for these rifles that would work?
2. Are there any known screws that are the same size and have the same pitch that can be modified to work?
3. Should I just try going somewhere (i.e. gunsmith) and have one custom made if possible?
4. Other options?

Oddball thread size on your LEC striker keeper screw is .126 inches diameter by 42 t.p.i.

The only other 42 tpi screw on the rifle is the extractor screw, which is of little use to you unless you get clever and can change the head or make a little washer....

Nothing that size in the Martini family either.

The other screw with the same thread is the "Screw, axis" in a P-14.

This is the one with the "spike" at the end that holds the bolt stop in place.

At the moment, I don't have one here to measure the head diameter.

Evans Custom Screw and Machine might be your answer. Scott has helped me out with a number of oddball Enfield screws, so he might be able to solve your problem and he's just a great guy to work with to boot.

Thanks for that useful lead. I just added his website to my favourites!

As I understand, Scott is winding down his screw making business. Get em while you can!

I have just been checking my Metford/Long Lee/ LEC spares box and I have found the screw you need. Infact there are around 20 of them all NOS. If you pm me your address I will send you one.

I was able to get a replacement screw thanks to Patt14 No2. Thank you for all the helpful responses!
