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.

Metric

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.

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

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.

Metric T-Tracks

Create custom jigs, fences, and setups with metric T-slot nuts and T-slot bolts. The slot in these T-tracks meets DIN 650, which specifies tolerances for machine tool tables, pallets, workpieces, and tool clamping devices. This ensures you can use them with DIN 508 T-slot nuts and DIN 787 T-slot bolts. Mount T-tracks to any flat surface or embed them to add fixturing to saw tables, CNC routers, and drill presses.

T-Slot Fixture Plates

These plates have T-slots for fastening components with T-slot nuts, bolts, and setup studs.

Metric

These plates have T-slots on all four sides and are milled flat on the top and bottom. The slots meet DIN 650, so they’re compatible with DIN 508 T-slot nuts and DIN 787 T-slot bolts for 8 mm wide slots.

Aluminum—Aluminum plates are lightweight and have mild corrosion resistance.
