    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.

    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.

    Keep out dust and contaminants and lock in air and fluid. As you tighten these corrosion-resistant screws, a rubber O-ring under the head compresses to form a tight seal. The deep, six-point socket keeps hex keys from slipping out and damaging the drive.
    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 screws can.

    Image of Product. Front orientation. Set Screws. Steel Cone-Tip Set Screws.
    Permanently secure parts that you don't intend to move. The pointed tip bites down on surfaces but may scratch or gouge. Made of alloy steel, they're strong enough to hold components without wearing down.
    Black-Oxide Alloy Steel—These screws have a dark matte finish that offers minimal corrosion resistance, so they're best for dry environments.
