Steel Socket Head Screws
 |
Fully Threaded |
Made of alloy steel, these screws are the standard for high-strength fastening. Use them in high-load applications such as dies, presses, and heavy equipment. The deep, six-point socket keeps the hex key from slipping out and damaging the drive.
Length is measured from under the head.
Cadmium-Plated Alloy Steel—The plating reduces friction between the screw and your mounting surface to prevent sticking when you tighten or loosen them. It also creates a barrier against rust.
Military Specification—Manufactured and tested to meet strict U.S. military standards for material and construction.
