A hex bolt (nut head, hex head bolt) is the most commonly used screw fastener in machine and equipment installations. The shape of the head provides a good grip, and the tools used for installation allow the fastener to be tightened to the correct torque.
The hex bolt is known by many names in everyday language, 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), hot-dip galvanized (KS, HDG), stainless steel (A2), and acid-resistant steel (A4).
