    Steel Socket Head Screws

    Image of Product. Front orientation. Socket Head Screws. Steel Socket Head Screws, Fully Threaded.

    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.
    Black-Oxide Alloy Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

    Image of Product. Front orientation. Rounded Head Screws. Stainless Steel Button Head Torx Screws.
    Our most corrosion-resistant button head Torx screws. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With a deep six-lobe opening, the Torx drive prevents your driver from slipping and stripping the drive. Also known as star drives, they withstand more torque than slotted, Phillips, and hex drives.
    Length is measured from under the head.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel can.
