Hi Can I use a 3/8"-20 BSW bolt in 3/8"-20 UNC thread? I'm making an adapter plate for my theodolite tripod so I can mount a camera or spotting scope. The tripod screw is 5/8" UNC and I've managed to source the drill and taps for this end of the plate. But at the other end, the tripod head has a 3/8" UNC socket and I need a bolt to screw into it. Just one. There are only about 5 turns in the socket. The only UNC bolts I can find on Ebay are from USA and the postage is ?27! So can I cheat and use a BSW bolt? Cheers

UNC & BSW interchangeable?

Through the letterbox this morning came a little package of two brass bolts, complete with nuts and washers, and a 3/8" BSW tap.

That's real kindness, totally unexpected and much appreciated. Thank you very much indeed.
