Steel 12-Point Screws
 |  |
Fully Threaded | Partially 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.
