Smooth Nylon Flange Nut DIN 6926 / Stainless Steel + Black Oxide
Nylon insert locking flange nuts have a non-serrated, flat underside and are able to withstand extreme vibrations without loosening. The smooth bottom flange acts as a built-in washer to evenly distribute force over a larger area against the fastening surface.
This nut does not damage the threads of bolts or screws and can be reused a limited number of times. Not recommended for higher temperature installations. Nylon insert color tone varies. Also known as prevailing torque hexagon nylon locking flange stop nut.
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.
