    Drop-In T-Slot Nuts

    Mount clamps and other fixtures to machine tool tables anywhere along the length of your T-slot track. These nuts install from the top and secure with a quarter turn, so you don’t have to slide them down the track’s length. They’re often paired with setup studs for adjustable fixtures. Also known as quarter-turn 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.
    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.
