Record vice

[P.K.]

Greetings.
I recently bought an old Record 52.5 E quick release vice. I’ve cut some wooden inserts for the jaws but none of the bolts I have are the correct thread. Anyone know the thread or pitch size?
Thanks

I think it depends on the vintage but if I remember correctly the older ones used 5/16 BSW screws.

Mine does.

Yep 5/16” BSW. I had to drill some out a No.4 last week so have just helicoiled them at M8
