Thank you for the information. It is the Pem studs and inserts I was looking for. Would engineering shops stock this sort of fastener or would I have to go direct to Pem, for a few to sample

Can anyone give me any advice on using self clinching nuts and studs in aluminium and steel material. Can they be manually fitted or do you need some sort of special press. Any advice or where to look would be very appreciated

Thanks for all the constructive advice. I've got to admit that it never crossed my mind that the offending part might have been 'homemade'. I just presumed it was a off-the-shelf part, so well spotted!

I might well try the allen bolt approach and see where to go from there.

Thanks for all the interest. I've found a youtube clip of the part in question and its intended use (but on a slightly smaller scale). The actual sprocket thing is shown in close-up at 2min 08secs

I've been busy with blu-tac and an empty ptfe tape spool to fashion a 3D example of what I'm failing to explain ! - Promise not to laugh as I won't make the 'Wallis and Gromit' claymation team !!

Thanks alot for all the suggestions, but we haven't find it yet. The studs are not protruding off the face but they are where the teeth would normally be

Thanks Ian P. but I'm thinking of something about 60mm diameter.

Like a studded dog collar to look at with one row of studs.

Any suggestions welcome.......please.......its doing my head in!

Sorry for this very vague description. I am trying to find out what this type of cog / sprocket / gear which has studs going around the circumference (not teeth but definitely studs) is called.

Does anyone know the correct name for this type of thing so I can find a supplier.
