    Stainless Steel Pan Head Phillips Screw Assortments

    Image of Product. Front orientation. Rounded Head Screws. Stainless Steel Pan Head Phillips Screw Assortments.
    Keep a variety of corrosion-resistant pan head screws on hand for a range of fastening jobs. These screws have a moderate height and width profile, offering a middle ground between narrower button heads and wider truss heads. The Phillips drive easily aligns with drivers and withstands more torque than slotted drives, but drivers slip when you apply too much force.
    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.

    Stainless Steel Button Head Hex-Drive Screw Assortments

    Image of Product. Front orientation. Rounded Head Screws. Stainless Steel Button Head Hex-Drive Screw Assortments.
    Keep a variety of corrosion-resistant button head screws on hand for a range of fastening jobs. Made of stainless steel, these screws won't rust, but they're not as strong as alloy steel. 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.

    Steel Button Head Hex-Drive Screw Assortments

    Image of Product. Front orientation. Rounded Head Screws. Steel Button Head Hex-Drive Screw Assortments.
    Keep multiple sizes of our strongest rounded head screws on hand for a variety of fastening jobs. These screws are made of alloy steel, so they have nearly twice the tensile strength of other 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.
