A flanged hex bolt (flange bolt, hex nut head, hex head bolt) is the most commonly used threaded fastener in machine and equipment assembly. The shape of the head provides a good grip, and the tools used for installation also provide a secure grip to tighten the fastener to the correct torque. The fixed flange (washer) under the bolt head speeds up installation. In everyday language, a hex bolt has many names, such as bolt, screw, machine screw, hex nut head screw, threaded bolt, or threaded screw, to name a few of the most common.
Materials: uncoated steel (ST), zinc plated (bright zinc, ZN, zinc), zinc flake (ZNF, Delta, Ruspert), stainless steel (A2), and acid-resistant steel (A4).
