Stainless Steel Hex-Drive Precision Shoulder Screws

Our go-to choice for assemblies that require smooth, accurate movement. These screws are engineered for tight tolerances, with shoulder diameters twice as precise as those on standard-fit screws. They're made of stainless steel, so they won't rust, though they're not as strong as their alloy steel counterparts.

Titanium Carbon Nitride (TiCN)-Coated 18-8 Stainless Steel—The outside layer of titanium carbon nitride reduces friction, which allows rotating and sliding components to move smoothly across screw shoulders.

Stainless Steel Low-Profile Hex-Drive Precision Shoulder Screws

Fit into tight spaces in corrosive environments. 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. 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.
