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.

Stainless Steel 12-Point Screws
 |  |
Fully Threaded | Partially Threaded |
These stainless steel screws won’t rust or corrode when exposed to moisture and chemicals. 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.
Extreme Strength—Our strongest 12-point screws. They hold up in the most demanding high-stress applications, such as in earthmoving equipment and heavy duty stamping.
