T-Slot Nuts

Slide into T-slot tracks on machine tool tables to secure clamps and workpieces. These nuts are often paired with setup studs for adjustable fixtures.

Black-Oxide Steel—Create a finished look with a dark, matte coating. These nuts offer minimal corrosion resistance, so they're best for dry environments.

Fully Threaded—Fully threaded nuts allow a stud to extend beyond the bottom of the nut.

Partially Threaded—Partially threaded nuts keep studs from traveling past the bottom of the nut and damaging your table.

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.

Machined Neck

Flat surfaces on the neck fit securely in the T-slot so the bolt doesn't wobble.
