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