Proto JSCR20 5/8 Inch Ratcheting Combination Wrench

Product Description

The PROTO JSCR20 is a 12-point ratcheting combination wrench designed for professional tradespeople who need reliable fastener control in tight service environments. Built from steel with a corrosion-resistant chrome finish, it features a 5/8 inch head size and a 15-degree offset angle on both the box and open ends. The overall length of 8-3/16 inches provides a comfortable reach-to-torque ratio for most standard fastener applications. The ratcheting box end reduces repositioning strokes, speeding up work in confined or overhead spaces. At 0.32 pounds, it is light enough for extended use without fatigue. This wrench meets ASME standards and carries a lifetime warranty.

The JSCR20 is suited for mechanical, HVAC, plumbing, and electrical trade applications where 5/8 inch fasteners are common. The straight handle and tether-capable design make it appropriate for elevated work environments, maintenance platforms, and service panels where dropped-tool hazards are a concern. The ratcheting box end is especially useful when working around pipe flanges, control cabinets, and equipment panels where swing arc is limited. It is not rated for non-sparking applications.

Installation Notes

This wrench is installed and used by licensed tradespeople and journeymen mechanics as part of a standard hand-tool kit. Always confirm the fastener size matches the 5/8 inch head before applying torque to avoid rounding. When using in tether-required environments, attach an approved tool lanyard to the tether point before beginning work. Do not use as a striking tool or apply extensions to the handle.
