Class 12.9 Alloy Steel 12-Point Screws Alloy Steel Torx Socket Flange Screws

Products Description

Good for high-strength fastening, these screws are made from steel comparable in strength to class 12.9 steel. 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. Head height includes the flange. Length is measured from under the flange.
