Proto JSCRM-10S Combination Wrench Set 10 Pc Metric

Product Description

The PROTO JSCRM-10S is a 10-piece metric combination wrench set designed for professional use in mechanical, industrial, and maintenance applications. Each wrench features a 12-point box end with a 15-degree head offset angle, giving technicians better clearance in tight or confined fastener locations. The set carries a black and chrome finish, balancing corrosion resistance with a low-glare working surface. Stored in an included pouch, the set is well-suited for field technicians, shop mechanics, and trade professionals who need a complete metric wrench spread in a compact, portable format. The set weighs 3.03 pounds total.

This set fits standard metric fastener applications across HVAC equipment, plumbing fixtures, electrical enclosures, and general mechanical assemblies. The 15-degree offset on the box end is particularly useful when working in recessed bolt patterns or near panel walls where a flat wrench profile would limit swing arc. Packaged in a soft pouch, the set is practical for service vans, tool bags, and job-site kits where organization and fast access matter.

Installation Notes

Combination wrenches are a hand-tool staple used by HVAC technicians, plumbers, electricians, and general mechanics. Always select the correct wrench size before applying torque to avoid rounding fastener heads. De-energize electrical systems and shut off gas or fluid supply lines before servicing any equipment that requires fastener removal. Inspect wrench ends for wear or damage before use, and avoid using extension cheater bars on standard combination wrenches.
