T-Slot Nuts
Designed to slide into T-slot tracks on machine tool tables, use these nuts to secure clamps and workpieces.
Fully threaded nuts allow a stud to extend beyond the bottom of the nut. Partially threaded nuts keep studs from traveling past the bottom of the nut and damaging your table.
Stainless steel nuts have excellent corrosion resistance. They are a good choice for use with stainless steel parts or in EDM applications.

Secure-Hold T-Slot Nuts
After sliding the nut into a T-slot track, tighten the set screw to keep it in place. Use these nuts to secure clamps and workpieces in a machine table. They’re fully threaded to allow a stud to extend beyond the bottom of the nut.

Drop-In T-Slot Nuts
Install these nuts from the top of the T-slot track and secure with a quarter turn to anchor clamps and workpieces. Also known as quarter-turn T-slot nuts.
Fully threaded nuts allow a stud to extend beyond the bottom of the nut.
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.
Stainless steel bolts have excellent corrosion resistance.
