    About Hex Head Screws and Bolts
    industrial info icon

    Choose a hex head fastener with the right threading, thread size, material, and strength for your equipment.

    Steel Hex Head Screws

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

    Partially

    Threaded

    Our most popular hex head screws. These have a head with six flat sides to keep wrenches and sockets from slipping and rounding off the drive.
    Length is measured from under the head.
    Medium-Strength Fastener—Your go-to screws for fastening most machinery and equipment. They have tensile strengths from 90,000 to 120,000 psi.
    High-Strength Fastener—Commonly used to fasten components in valves, pumps, motors, and other high-stress applications. These screws have a tensile strength of 125,000 to 160,000 psi.
    Steel—Unfinished steel screws are best for dry environments, since moisture will cause them to rust. They require little surface prep before applying a finish, so you can apply your own paint or coating.

    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—Best for dry environments since moisture will cause these screws to rust. They have a dark, matte appearance.

    Threaded Rods

    Anchor, connect, or hang components in a wide variety of applications, from mounting I-beams to suspending light fixtures.
    Medium-Strength Steel
    Image of Product. Front orientation. Threaded Rods. Threaded Rods.
    With tensile strengths from 110,000 psi to 125,000 psi, these rods are strong enough for most industrial applications, such as anchoring machinery and connecting pipe flanges. They are about twice as strong as low-strength steel rods. To avoid stripped threads during installation, make sure your nuts are also medium-strength steel.
    Steel—Best for dry environments since moisture will cause these rods to rust.

    High-Strength Steel
    Image of Product. Front orientation. Threaded Rods. Threaded Rods.
    With a tensile strength of 150,000 psi, these rods are strong enough to stabilize steel frameworks and structural supports, such as I-beams. They are about 25% stronger than medium-strength steel rods. To avoid stripped threads during installation, make sure your nuts are also high-strength steel.

    With a tensile strength of 50,000 psi or 60,000 psi, these rods are often used to suspend light fixtures, cable trays, and conduit from ceilings. They're about half the strength of medium-strength steel rods. To avoid stripped threads during installation, make sure your nuts are also low-strength steel.

    Eyebolts—For Lifting

    Create a secure attachment point for hooks, shackles, and other lifting equipment. Also known as machinery eyebolts, these eyebolts are used to lift heavy machines and materials. They have a closed eye that won’t bend under strain.
    Warning: Never use to lift people or items over people. Capacities listed are for vertical lifting only.

    Create your own lifting eye by adding an eye nut to a stud or bolt.
    Note: Capacity applies to the eye nut only. The stud or bolt you use will affect the overall capacity. Eye nuts are for vertical lifting only.
    Warning: Never use to lift people or items over people.

    Rotating Eyebolts—For Lifting

    Unlike conventional eyebolts, you can rotate the eye 360° to match the angle of your load.
    Note: Capacities listed are for vertical lifting only. Eyebolts with shoulder can be used for angular lifting up to 45°, but the capacities will be significantly reduced. For angular lifting, we recommend Hoist Rings.
    Warning: Never use to lift people or items over people.
