Heavy Hex Nuts

Heavy Hex Nuts are larger and thicker than standard (finished) hex nuts.The heavy hex pattern is typically used for large diameter and high strength bolts, and with certain high-strength grades of steel can be used with structural bolts in structural applications.

A heavy hex nut is visibly different from a normal hex nut or finished hex nut in that it is bigger and stronger. Hex Nuts are hexagon nuts with six sides that are used to tighten bolts and screws. Its use, however, is not restricted to hex-headed bolts. The hexagonal body allows for fast wrenching while still applying sufficient torque to the bolting joint. Both types of bolts can be used with hex nuts. Hex nuts are also known as hexagon nuts or six-sided nuts. With unified national coarse pitch (UNC), fine pitch (UNF), fixed pitch (Un), and ISO metric thread profiles, hex nut dimensions are described in both metric and imperial sizes. These are available in a variety of materials and ASTM requirements.
Common applications of Heavy Hex Nuts are:

  • • Structural
  • • Machinery
  • • Automotive
