Hi everyone

Does anyone know the size of these screws, I am building a couple of lock kits I picked up and these screws are missing.

I THINK they are 8x32. Try one from a hardware store and see.Better yet call Chambers.

I believe you are correct Bob. I tried an 8x32 from another lock and that was the size used.

Thanks

Why not just buy them from Jim Chambers?

The Log Cabin Shop should have them

Geeze it seems any lock builder should have a micrometer and a thread pitch gage! Not much of a tooling commitment.

All of the Bridle and sear replacement screws I`ve had to make were 6-40

All of my locks used 4x40 or 48 like the British locks.IF need be the holes can enlarged to 5x40 or 48. 6x40 for hammer to tumbler.
