Clamping and Workholding

T-Slot Bolts

For quicker setups than a separate T-slot nut and stud, slide these bolts into T-slot tracks on machine tool tables.

T-Slot Nuts

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.

Setup Studs

Combine these setup studs with T-slot nuts, flanged nuts, setup clamps, or setup blocks to clamp and hold workpieces, vises, and other objects onto your fixturing table. Also known as double-ended studs, they have threads on both ends.

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.

T-Slot Nut and Setup Stud Kits

For mounting items to your machine table, these kits contain the full system of necessary components.

T-Slot Blocks

Mount these versatile blocks to any flat surface for machine table-style T-slot clamping. They can also be used on a machine table to clamp parts at specific angles or add more total clamping points.
