Waterproof Anchor Bolt

A waterproof anchor bolt is a specialized fastener designed to secure structures while preventing water ingress. Typically made of corrosion-resistant materials like stainless steel or coated carbon steel, it features a threaded shaft and a head (hex, round, or countersunk). The key waterproofing elements include rubber gaskets, neoprene washers, or expandable sleeves that create a tight seal between the bolt and the mounting surface. Common applications include marine structures, bridges, tunnels, and outdoor construction where moisture resistance is critical. Installation involves drilling a hole, inserting the bolt with sealing components, and tightening to compress the waterproofing materials, ensuring long-term durability in wet environments.
