Jam Nut, 5/16″-18, Steel, Grade A, Zinc Plated, 50 PK

$6,59

The term “jam nut” comes from its use as a secondary nut that jams the main nut. Jam nuts help to prevent loosening in cases where the bolt may be subject to vibration. In situations where you need to fasten a threaded rod or hanger bolt, a jam nut can be tightened against a regular nut in order to create a place for a wrench to be used. They can also take the place of a standard nut in cases where there is not enough exposed thread to support the thickness of a standard nut.

  • Size: 5/16 inch-18
  • Similar in shape and function to a standard finished hex nut but is about half as thick
  • Used as a second nut to “jam” or prevent the main nut from loosening
  • Can also be used in place of a standard finished hex nut in cases where a standard nut will not fit
  • If using one thin nut and one standard nut, the thinner nut goes in first
  • Thread Type: Coarse, Thread Class: UNC-2B
  • Specification(s) Met: ASME B1.1 & SAE A563
  • Out of stock
