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

    Partially 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.
    Zinc-Plated Alloy Steel—A common choice for areas with occasional exposure to moisture.
    Zinc-Flake-Coated Alloy Steel—The coating is tested to extreme standards, including at least 700 hours of salt spray resistance, to hold up in wet and outdoor environments.

    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.
    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.
    Standard Profile—Standard-profile heads are the most common choice for flat head screws.

    Made-to-Order Same-Size Thread Stainless Steel Hex-Drive Shoulder Screws

    Image of Product. Front orientation. Shoulder Screws. Made-to-Order Same-Size Thread Stainless Steel Hex-Drive Shoulder Screws.
    Harness superior holding power with custom-shoulder-length screws that also won't rust. These are ideal for replacing fasteners in older machines or for testing prototypes. Threads that match the shoulder diameter give them a tighter hold than screws with a standard thread diameter. Use them in thicker materials and larger holes.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
