Thread-Locking Steel Hex-Drive Shoulder Screws

Immune to vibration, these screws won't loosen and are also fit for high-strength fastening. A threadlocker pellet is embedded into their threads, saving you the hassle of adding it yourself. The pellet compresses as the screw is tightened, which gives it more locking power than a patch. These screws are twice as strong as other standard-fit thread-locking shoulder screws, but will rust if exposed to moisture or chemicals.

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.

Shoulder Shims


Shoulder Shortening	Shoulder Lengthening

Shoulder Shortening—Pare down the shoulder on screws or tighten the screw's hold. Stack multiple shims to get the exact spacing you need.

Shoulder Lengthening—Wiggle over threads to add space or increase travel along the shoulder of screws. Stack these shims to get the exact spacing you need.

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.
