About Threaded Studs and Rods

Screws for Carbide Insert Holders

When it's time to replace the screws in a carbide insert holder, use the reference number on your holder to find the right size.

Setup Studs

Secure setup clamps and fixtures to your machine table, or assemble heavy machines, such as engine mounts.

Vibration-Resistant Setup Studs

Also known as tap-end and fixture studs, these rods have friction-fit threads on one end to resist loosening and standard threads on the other side for attaching a nut.
