Bondtech gear grub screw

I'm having a challenge with the bondtech drive gear coming loose.  I've tried to tighten it but I think the grub screw may have a damaged hex socket and thus never fully tightens.

Can anybody tell me the specs of the grub screw so that I can source a replacement to see if that resolves the problem without buying a whole new gear set as being UK based shipping costs silly money right now.

Yes and the answer is there.  The key is know which one you are replacing.

I found the bondtech ones but could only buy the whole set for £30 seemed a lot of money.  Thanks for the help though.

Try grub screws from X or Y axis spares

I bought a set of spare pulleys when I did the moons stepper motor upgrade - you can get 6 pulleys for about 5 bucks.  Each of them has 2 grub screws in them that should be a match.  They aren't special either - just search setscrews M3x2mm in any tool catalog and you should be able to get a hundred of them pretty cheap.
