HEX FLANGE NUT PLAIN 5/8"-11 GR 8
X8FN5811
- A flange nut has a wide flange at one end that acts as an integrated washer.
- The flange serves to distribute the pressure of the nut over the part being secured.
- Less likely to loosen as a result of an uneven fastening surface.
- Non-serrated.
- Meet SAE J995.
- Normally used in conjunction with grade 8 frame/flange bolts.
- Size: 5/8"-11.
