    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 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.
    Zinc-Plated Alloy Steel—A common choice for areas with occasional exposure to moisture.
    Standard Profile—Standard-profile heads are the most common choice for flat head screws.
    Undercut Profile—About a third thinner than standard heads, the undercut profile fits into shallow holes in thin material. The thin head also has more threading on the shaft, so they're often used to keep short screws from coming loose.

    Stainless Steel Button Head Hex-Drive Screws

    Image of Product. Front orientation. Rounded Head Screws. Stainless Steel Button Head Hex-Drive Screws.
    These button head screws won't corrode from moisture and chemicals, but they aren't as strong as alloy 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.

    Steel Torx Plus Socket Head Screws

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

    Fully Threaded

    The deep, six-lobe socket of these Torx screws withstands even more wear and torque than hex drives. They resist stripping, even after repeated tightening. These screws are a good choice for equipment that requires frequent adjustments, such as jigs. Made of alloy steel, these are our strongest socket head screws.
    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 Thread-Locking Socket Head Screws

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

    Fully Threaded

    Lock parts in place on vibrating machinery. These screws have threads with a bonded nylon patch, saving you the time and mess of adding threadlocker yourself. Made of alloy steel, these are some of our strongest screws. Their deep, six-point socket keeps hex keys 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 Torx Plus Flat Head Screws

    Image of Product. Front orientation. Flat Head Screws. Steel Torx Plus Flat Head Screws.
    The strongest Torx Plus flat head screws we offer. They're made of alloy steel, so they have nearly twice the tensile strength of other screws. With larger lobes than Torx drives, Torx Plus withstands even more torque 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.

    Brass Button Head Hex-Drive Screws

    Image of Product. Front orientation. Rounded Head Screws. Brass Button Head Hex-Drive Screws.
    These button head screws have a shiny look and won't rust in damp environments. Made of brass, they're also conductive and nonmagnetic, making them useful for electrical applications. 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.
