    Partially Threaded

    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.

    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.
