    Steel Hex-Drive Shoulder Screws

    Image of Product. Front orientation. Shoulder Screws. 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.

    These screws hold up against moisture and chemicals better than their steel counterparts, but they aren't as strong.
    Check out our Made-to-Order Stainless Steel Hex-Drive Shoulder Screws if you don't see the shoulder length you need.
    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.
    Black-Oxide 18-8 Stainless Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They won't rust in wet and outdoor environments, but they won't hold up to the harsh chemicals that 316 stainless steel can.
    Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these screws won't degrade when exposed to harsh weather, salt water, and most chemicals.
    Highly Corrosion-Resistant Black-Oxide 316 Stainless Steel—Combines a finished appearance with the rust resistance of 316 stainless steel. Even if the coating wears off, these screws will hold up against corrosive agents in most environments, including salt water and most chemicals.
