Lag Screw Hinge Bolts are a type of fastener used in hinge applications, especially for gates and doors. They are designed with a lag screw thread on one end that is used to anchor the bolt into a wooden surface, while the other end features a hinge pin that fits through the hinge strap or plate. These bolts are made of durable materials such as steel or stainless steel to provide strength and longevity, and are available in various sizes to accommodate different hinge applications.
