Stainless Steel Waxed Nylon Insert Lock Nuts

Wax Coated Nylon Lock Nut to Eliminate Thread Galling

  • Treated with wax to act as an on board anti-seize to prevent thread galling
  • The prewaxed nut saves you from having to apply anti-seize to every nut
  • Perfect for assembly lines, factories, or anyone who wants to save time and money
  • Also referred to as Waxed Nylon Lock Nuts, Nyloc Nuts, Polymer-Insert Lock Nuts, or Elastic Stop Nuts
  • UNC Coarse and UNF Fine Thread sizes available
  • Nylon Insert prevents loosening of fastener assembly
  • Cross threads stop nut from backing off the fastener

*Even when using Waxed Nylon Insert Lock Nuts, we still recommend using an MRO Anti-Seize Solution to further deter thread galling during any stainless steel fastener installation.
