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.

Steel Low-Profile Slotted Precision Shoulder Screws

Fit these slotted screws into shallow holes and low-clearance spaces where smooth and accurate movement is required. The head is about one-half to two-thirds the height of standard-profile screw heads, so they're not suited for high-strength fastening. They are stronger than their stainless steel counterparts, but weaker than standard-profile screws. Engineered for tight tolerances, their shoulder diameters are twice as precise as those on standard-fit screws. Hand-tighten with a slotted screwdriver to avoid damaging the drive.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

Same-Size Thread Steel Hex-Drive Shoulder Screws

Harness superior holding power with screws that also won't break. Threads that match the shoulder diameter give these a tighter hold than screws with a standard thread diameter. Use them in thicker materials and larger holes. While twice as strong as stainless steel screws, they're not corrosion resistant.

Steel Headless Slotted Precision Shoulder Screws

With no head, you can flush mount these screws in countersunk holes and tight spaces. You can also use them as pins for aligning parts. They are engineered to tight tolerances for assemblies that require smooth and accurate movement, with shoulder diameters twice as precise as those on standard-fit screws. Hand-tighten with a slotted screwdriver to avoid damaging the drive.

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.

Steel Low-Profile Hex-Drive Shoulder Screws

Fit into shallow holes and in low-clearance areas around moving parts. The head on these screws is about one-half to two-thirds the height of standard-profile screw heads, so they're not suited for high-strength fastening.
