    Image of Product. Front orientation. Hex Head Screws. Mil. Spec. Steel Hex Head Screws, Partially Threaded.

    Partially

    Threaded

    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.
    Grip Length—Screws with a grip length have a precisely measured unthreaded section under the head, called a grip. It's stronger than the threaded section, so you can place it in joints exposed to sideways forces.
