A Nylon Insert Hex Jam Nut, sometimes called a Nylon Jam Nut or Nylon Jam Lock Nut, is a low profile lock nut used for fastening to a bolt when mechanically joining materials together. The nylon material located at the top of the nut prevent loosening from vibration. Nylon Insert Jam Nuts in this selection are made of 316 Stainless Steel suitable for corrosion resistance in harsh environments including those exposed to salt water.
To prevent or stop galling (also known as seizing or locking-up) on stainless steel fasteners, we recommend using an anti-seize thread lubricant from our line of MRO Solutions
