T-Slot Nuts

Steel

Stainless Steel

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.
