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.

Stainless Steel Slotted Precision Shoulder Screws
 |
Use these slotted screws in assemblies that require smooth, accurate movement. They're 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. Hand-tighten with a slotted screwdriver to avoid damaging the drive.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Stainless Steel Low-Profile Slotted Precision Shoulder Screws
 |
Fit these slotted screws into tight spaces in corrosive environments. 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 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.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
