    12-Point-Drive Flange Nuts
    3D CAD models available

    The star-shaped head has more points of contact than a hex head nut, so you can achieve a better grip and a tighter fit without flattening the sides of the nut. Great for cramped spaces without a lot of clearance, these nuts twist on from any angle with a standard wrench. They have a flange that distributes pressure evenly across the mounting surface without the need for a separate washer. Also known as collar nuts.

    Black-Oxide Steel—Typically chosen for their appearance, these nuts have a dark, matte coating that creates a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

    Threaded

    Good for high-strength fastening, these screws are made from steel comparable in strength to Grade 9 steel. Use them for heavy duty stamping applications as well as earth-moving machinery, such as bulldozers and excavators. The head makes 12 points of contact with a wrench to handle more torque than a socket head or hex head screw. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. To install, use a 12-point wrench that matches the head width of your screw.
    Black Oxide—Black-oxide coated screws are mildly corrosion resistant in dry environments.

    These hardened stainless steel screws combine excellent corrosion resistance with strength comparable to Grade 9 steel. Use them for heavy duty stamping applications as well as earth-moving machinery, such as bulldozers and excavators. The head makes 12 points of contact with a wrench to handle more torque than a socket head or hex head screw. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. To install, use a 12-point wrench that matches the head width of your screw.
    18-8 Stainless Steel—18-8 stainless steel screws have good chemical resistance and may be mildly magnetic.
    450 Stainless Steel—450 stainless steel screws are more corrosion resistant than 18-8 stainless steel screws and have good resistance to chemicals and salt water. They are magnetic.
