5/16″ Ring and Open End Spanner – Mirror Polished

Powerbuilt combination wrenches are constructed from tough heat-treated chrome vanadium steel for strength and durability that resists wear better than steel alone
With precision bevelled flats (up to 32mm/1 1/4) for easy mating to bolts and a knuckle-saving 15 offset, consider these your new go-to combination wrenches
The box ends also feature Z-Drive design that contacts the flat walls of fasteners for better grip and less chance of rounding up to 32mm/1 1/4
Built to exceed ANSI specifications
