Works great, good price, ordered more

Bought these to use on the fuel line retaining bolts so I don't have to juggle the nut and washer. They aren't scored, so they won't chew on anodized aluminum. They work great. The warped thread lock works great. I've been looking for a while to find 1/4-20 serrated lock flange nuts at a reasonable price.

Pros
  • nuts
Cons
  • thin
