1/4-20 Hex-Head Bolt, 18-8 SS, Hex - Choose Your Length

1/4-20 18-8 Stainless Steel Hex-Head Bolts – Choose Your Length

Get dependable fastening performance for woodworking, construction, repair, and outdoor projects with these 1/4-20 hex-head bolts. Made from corrosion-resistant 18-8 stainless steel, these bolts are an excellent choice for applications where exposure to moisture and the elements makes standard zinc-plated fasteners prone to corrosion.

Unlike wood screws, bolts create strong mechanical joints that do not depend on threads cut directly into the wood. This makes them particularly useful for structural and heavy-duty assemblies such as decks, docks, outdoor furniture, timber projects, and other construction applications.
