About Nuts, Materials, and Finishes

Zinc-Plated Steel

These inserts have four prongs on the flange to resist twisting in hardwood and softwood. Hammer them into a drilled hole to install. Installed length includes the flange.

Zinc-plated steel inserts are mildly corrosion resistant in wet environments.

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.

End-Feed Fasteners

Single Nut

Double Nut

End-feed fasteners slide into the end of the rail to attach components.

Use double and triple fasteners to install brackets with multiple holes. They eliminate the need for a single nut and screw for each hole.
