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.
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.
