Nylon Lock Nut DIN 985 / Stainless Steel + Black Oxide
This locking nut relies on a nylon insert to create interference between the mating threads of a bolt or threaded rod. The nylon insert compresses to securely fasten the nut against the bolt, ensuring resistance to vibration and loosening.
Finish: Black Oxide
Abrasion resistant, does not peel, chip or rub off
Reduces friction, prevents galling
Does not change the strength of the stainless steel
Practically no dimensional change to base fastener
The spray applied during the coating process wears off over time, revealing an attractive matte black finish
The black oxide coating per MIL-DTL-13924, Class 4 on 300 series corrosion resistant steel meets 96 hours of resistance in a 5% salt spray (fog) test in accordance with ASTM B117. We recommend using stainless steel installation tools to prevent extraneous rust.
Stainless nylon lock nuts are commonly used in damp environments for corrosion resistance, popular across a wide range of industries: automotive, agriculture, food processing, clean energy, etc.
For any application involving marine (salt water), use A4 / 316 Stainless Steel material, available in bulk packs and as a special order.
Nylon lock nuts will not damage the threads a bolt or screw. Nylon insert color tone varies. Nylon nuts are of the most popular methods of fastener locking. Also known a Nylon Lock Nut or Prevailing Torque Lock Nut.
