    Stainless Steel Slotted Precision Shoulder Screws

    Image of Product. Front orientation. Shoulder Screws. 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.
    Military Specification—These screws are manufactured and tested to strict U.S. military standards for material and construction.
