Stanley No 50

Would anyone know the thread size of the screws that holds the little spurs in place, cheers

If noone else replies, will have a check with thread gauge tomorrow. But there are only two or three threads on them, so there may be some ambiguity.

Thanks **** that would be very helpful

Well......... best guess (tricky even under microscope) is 0.16" diameter by 36t.p.i. So possibly 1/8" by 36? Trouble is, there are only 2 or 3 threads visible, so difficult to be 100% sure. Checked with the tables, and none of the standards (Whit., UNC/F or BA) corresponds, as 1/8" is 40 tpi in Whit /UNC, or the nearest B.A. is 43 tpi! Nothing remotely similar in metric, so probably the usual "Stanley special". But with the short length involved, you could probably get away with Whit or UNC?

Cheers ****, thanks for taking the time to do that.

Doug.
