    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.
    Partially Threaded—Partially threaded nuts keep studs from traveling past the bottom of the nut and damaging your table.

    T-Slot Bolts

    For quicker setups than a separate T-slot nut and stud, slide these bolts into T-slot tracks on machine tool tables.
    Machined Neck
    Image of Product. Top orientation. Contains Annotated. T-Slot Bolts. Machined Neck.
    Flat surfaces on the neck fit securely in the T-slot so the bolt doesn't wobble.
    Black-Oxide Steel—Our strongest T-slot bolts. The dark, matte coating withstands occasional moisture.
    18-8 Stainless Steel—Won't rust or corrode from water or chemicals. These bolts may be mildly magnetic.

    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.
