Detail & Specs
Smooth Bottom, Coarse DIN 6923 Flange Nut / Black Stainless Steel
Non-locking flange nuts have a smooth bottom flange that acts as a built-in washer to evenly distribute force over a larger area against the fastening surface.
This non-serrated nut will not damage the threads of bolts or screws and can be reused. Also known as hex nut with integrated washer.
Material: Stainless Steel
Suitable for damp locations
Corrosion resistant
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.
