I have a bolt which,after the nut has been threaded on a certain distance,pivots downwards,effectively stopping the nut from running off the bolt. I wonder if anyone knows the name of this type of bolt and,indeed,if they are currently available. I do not relish the idea of making some. It is from a 1920 motorbike.

A photograph, as ever in these situations, would help! smiley

I think it was an idea that did not catch on. Never seen or heard of such bolts in half a century of messing with machinery, including 1920s motorbikes. But also sure would like to see a photo or drawing of such.

I'd say your choices are make your own -- could be an interesting exercise but can't quite visualize it -- or use holes and split pins like most other bikes of the era.

What sort of bike is it from, and what part does it secure?

Sounds like a threaded version of a clevis pin like this one with an end that pivots to lock in place.

I've not seen a threaded version before, but If you Google 'drop nose pin' and select images you'll see plenty of variations.

Sorry I haven't replied to these posts but have been having a bit of resection,I think that's what it's called. Anyway up, completely my fault,I didn't derust and clean up the pin. It was a pin after all.. So the above information was correct and very useful.Thankyou all very much. New post coming up about brass soldering,(again)

Apparently they go by many names. Hinged Pin,Drop Nose Pin,Link Pin,Dead Link Hinge Pin. The only problem is no-one seems to make them in the size that I want. They are mostly for marine applications and are either too small or too large...... I will keep searching as I don't think I can make one!

Have you tried the chandlery or dinghy spare part outlets such as Force4 or Harkin we use those pins from 3mm dia by 10mm long up to 20mm dia by 100mm long for the yachts

try searching for Clevis Pin

Perhaps try a castle nut and split pin such as these: **LINK** or maybe you could use a different type of locking nut ?
