    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.

    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.

    Steel Button Head Hex-Drive Screws

    Image of Product. Front orientation. Rounded Head Screws. Steel Button Head Hex-Drive Screws.
    Made of alloy steel, these screws have nearly twice the tensile strength of other steel screws. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver.
    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.
