Square Head Machine Bolts

Square Head Machine Bolts are a type of fastener commonly used in pole line hardware for electrical power distribution and transmission systems. These bolts have a square-shaped head that allows for easy tightening and loosening using a wrench or a socket wrench. Square Head Machine Bolts come in various lengths and diameters to accommodate different pole line hardware applications. They are typically made of steel or other durable materials to withstand the rigors of outdoor environments and the loads experienced in power distribution systems. They are often used alongside nuts and washers to create a secure assembly that can withstand environmental factors and mechanical stresses.
