Re: [FTC]: Axle Set Collars (Vex, Master-Carr)

We participate in BEST robotics which provides a specific supply of materials in the KOP. We use modified 1/4-20 nuts as shaft collars.

We drill out the threads of the nut with a 17/64 or 9/32 drill bit. We then drill a tap hole in the side of the nut for an 8-32 bolt. You might be able to manufacture you own this way rather buying.

You could try the same technique with a small nut with a smaller bolt as the set screw.

Good luck.
