Designed to slide into T-slot tracks on machine tool tables, use these nuts to secure clamps and workpieces.

Drop-In T-Slot Nuts

Install from the top of the T-slot track and secure with a quarter turn. Also known as quarter-turn T-slot nuts.

Secure-Hold T-Slot Nuts

After sliding the nut into a T-slot, tighten the set screw to keep it in place.

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.
