At a glance
| Wrench size (across flats) | 3/4" |
| Thread | 1/2-20 UNF (Fine) |
| Material | Steel |
Good to know
- Fine (UNF) thread — higher tensile strength and better resistance to loosening than coarse.
- An all-metal distorted thread grips the bolt with no nylon — holds under heat and heavy-duty reuse where a nylon-insert nut would fail.
