    Steel Hex-Drive Flat Head Screws

    Image of Product. Front orientation. Flat Head Screws. Steel Hex-Drive Flat Head Screws.
    Our strongest hex-drive flat head screws. They're made of alloy steel, so they have nearly twice the tensile strength of other screws. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver without slipping and stripping the drive.
    Length is measured from the top of 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.
    Standard Profile—Standard-profile heads are the most common choice for flat head screws.
    Military Specification—These screws are manufactured and tested to meet strict U.S. military standards for material and construction.
