clamshell catches

[ProtoTipo]

Ok, the binder pins have arrived.

See photo. I have replaced the missing long pin on the catch on the left.
Compare the original circlip pin (fitted to the catch on the right) with the binder pin and binder pin fastener/bolt.
The binder pin does the job, and it's solid metal all the way to the threaded part.
I chose 5mm x 30mm.

The only worry would be it unscrewing itself. So some good quality thread lock or maybe even epoxy might be a good idea?
In the case of a used catch, after the parts have been refurbished, obviously.
