At a glance
| Thread | 5/16-18 UNC (Coarse) |
| Material | Steel |
Good to know
- Coarse (UNC) thread — faster to install and more tolerant of nicks and corrosion.
- Serrations on the flange face bite into the surface to resist vibration loosening, with a built-in washer face that spreads load (marks the surface, so not for finished faces).
