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.

Metric

7075 Aluminum—Won’t scratch or wear down aluminum T-slot tracks. These nuts have a steel insert for strength, extending their life.

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.

18-8 Stainless Steel—Stainless steel nuts have excellent corrosion resistance. They are a good choice for use with stainless steel parts or in EDM applications.

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

DIN 508—Nuts meet DIN dimensional and material requirements. Slide them into DIN 650 T-slots.
