You should try your local fastner supplier, 25p ea.
I am getting some 7/32" 28TPI BSF bolts made this week by a local clockmaker.
I have purchased a die specifically for the job.
Please let me know if you would like a pair.
They will be domed cheese head 9.0mm diameter
7/8 Inch shaft length. They will not fit the Cadet Major as far as I know?
The chap will true up and then lathe down a larger screw and then thread it.
This will all have to be done by hand one screw at a time so it won´t be mass-production prices...
Not sure on the price yet but I think they will be 7 quid a pair posted UK
Chamber when they have them charge 7.73 EACH plus postage...
The more I get made the cheaper they will be per unit.
Cheers

Opportunity is missed by most people, because it is dressed in overalls and looks like work.

recently had a laugh at the price of stock screws on chambers site,and for less than chambers wanted for two screws/postage, i bought 50 stainless steel hex head,from screwfix direct. [m5-12mm] is size.fit most weihrauch.
I searched ad nauseam for a supplier of 7/32" 28TPI BSF threaded cheese heads and could not find any
My clock maker has made up a screw from a die I purchased but the screw won't fit the gun
2 people on here told me that the treads for the screws were this gauge but it seems they are not?
Perhaps different Cadets have different sizes?
Very frustrating - and expensive

when I need screws it involves a 26mile round trip so perhaps more than 25p each. My supplier is Norton Fasteners in Letchworth Herts. They are very helpfull, and have always identified the thread pitch.
Thanks Terry I will bear them in mind
1/4 BSF (8/32") is the smallest common size understandably and these are available from everywhere you can think of.
Why a manufacturer of a gun would choose to go that small step down from the common 8/32" to the little used 7/32" baffles me somewhat

Many ( if not most ) gunmakers did it. I formed the opinion that it was to prevent you repairing their products with readily available off the shelf stuff.
I find a common size on guns is .203" (13/64") diameter. This is just .015" smaller than the 7/32" under discussion, and is a non-standard size, thus necessitating return to or spares from the maker. Unless you are a toolmaker! Also, BA threads are not uncommon.
Well the 7/32 thread that my chap has run up is too tight in the gun so maybe it is this 13/64
I too hold the same opinion that it's to make you spend more money
Just spoken to my chap who will now grind a small piece off the open gap in the die to enable it to be closed down even further.
I gave him a screw out of my 1949 Major and this fits the die - but loosely! This seems to bear out the 13/64 theory! Crafty beggers...

would it not be quicker to weld/fill holes retap in metric /or more common size.
You could, of course, bite the bullet and just buy the right ones from Chambers and do away with all the pissin about!
