    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
    Image of Product. Front orientation. Contains Annotated. T-Slot Nuts.
    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.
    Partially Threaded—Partially threaded nuts keep studs from traveling past the bottom of the nut and damaging your table.
    DIN 508—Nuts meet DIN dimensional and material requirements. Slide them into DIN 650 T-slots.

    Robot Arm and Attached Tools Not

    Included

    With a top that’s T-slotted from edge to edge, these workstations let you endlessly adjust your robot and fixtures as you iterate setups. Optimize them to hold workpieces, trays, sensors, and more for a variety of robot tasks, from machine tending to dispensing glue. Use the included mount to secure FANUC CRX, Universal Robots (UR), or other common robot arms anywhere on the workstation top. These workstations come fully assembled with hardware to attach the mount to the workstation. However, you’ll need fasteners to attach your robot to the mount.
    These workstations have swivel casters with brakes, so you can roll them between jobs and lock them in place. Store your teach pendant, robot controller, and other accessories behind the cabinet doors below—or remove the doors for easy access.

    Weld permanent threads in channels and other tight spaces without adding a barrel bump that gets in the way. These nuts have a short barrel that tucks under low surfaces and a slim footprint that fits between narrow channel walls.
    Steel—Best for dry environments since moisture will cause them to rust. Made of uncoated steel, these nuts require minimal prep. Weld them to uncoated steel surfaces.
    18-8 Stainless Steel—Suitable for outdoor use, these nuts resist rust from water and mild chemicals. Weld them to stainless steel surfaces.
