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.
