A Carriage Bolt Washer is a flat, circular disc with a central hole, designed to be used with a carriage bolt (also known as a coach bolt). The washer helps distribute the load and prevent damage to the fastened material. Carriage bolts typically have a smooth, domed head and a square section beneath the head that prevents rotation when tightened. The washer ensures a secure fit and improves the bolt’s clamping force.<\/p>\n
