This 18-8 stainless steel hex head cap screw features a partial thread, providing a smooth, unthreaded shank beneath the head for increased shear strength in heavy-duty joints. The high chromium and nickel content ensures excellent resistance to rust and corrosion, making it a dependable choice for projects exposed to moisture or chemicals. Designed for use in through-holes with a nut, the unthreaded portion allows for precise alignment and a tighter grip between fastened components. This fastener combines the structural integrity of a partial thread with the long-lasting durability required for professional fabrication and outdoor assembly.
