The Proto J1213MHASD is a 13mm metric combination wrench featuring the Torqueplus fastening system, which drives off the body of the fastener rather than the corners — applying up to 15% more torque while significantly reducing the risk of rounding damaged fasteners. Its unique arc design increases surface contact by 400% for a stronger, more reliable grip on fastener heads.
Built for professional MRO and industrial applications, this single 6-point combination wrench delivers open-end versatility alongside a closed box-end for added torque. The satin finish resists corrosion and minimizes glare in the workplace, making it a dependable addition to any toolbox.
