    Steel Hex-Drive Shoulder Screws

    Image of Product. Front orientation. Shoulder Screws. Steel Hex-Drive Shoulder Screws.
    Our strongest standard-fit shoulder screws. With the highest tensile strength, they withstand stress and mechanical loads that would break other materials, such as aluminum, nickel, and stainless steel. However, they do sacrifice corrosion resistance.
    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.

    Eyebolts—For Lifting

    Also known as machinery eyebolts.
    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. Eyebolts without shoulder are for vertical lifting only.
    Warning: Never use to lift people or items over people.
