Mil. Spec. Steel Hex Head Screws
 |  |
Partially Threaded | SAE Grade 5 |
Manufactured and tested to meet strict U.S. military specifications for material and construction. These screws have a head with six flat sides to keep wrenches and sockets from slipping and rounding off the drive.
Length is measured from under the head.
Medium-Strength Fastener—Your go-to screws for fastening most machinery and equipment. They have tensile strengths from 90,000 to 120,000 psi.
Cadmium-Plated Steel—The plating reduces friction between the screw and your mounting surface to prevent sticking when you tighten or loosen screws. It also creates a barrier against rust.
