At a glance
| Wrench size (across flats) | 7/16" |
| Thread | 1/4-28 UNF (Fine) |
| Material | 18-8 Stainless |
Good to know
- Fine (UNF) thread — higher tensile strength and better resistance to loosening than coarse.
- A nylon collar grips the bolt threads to resist loosening; rated to roughly 250°F — use an all-metal lock nut above that.
- 18-8 Stainless — corrosion-resistant and non-magnetic.
