Stainless Steel Hex Nut

Hex nuts are one of the most common nuts available and are used with anchors, bolts, screws, studs, threaded rods and on any other fastener that has machine screw threads. Hex is short for hexagon, which means they have six sides. Hex nuts are also known as: finished hex nuts, hex full nuts. Lock washers may used with hex nuts. Threads are standard right-hand and Unified inch coarse series (UNC, Unified National Coarse) or Unified inch fine (UNF, Unified National Fine). Left-hand threaded hex nuts are also available—see Left Hand Nuts.
