Proto JSCRM13 Combination Wrench 13 Mm Ratcheting

Product Description

The PROTO JSCRM13 is a 13 mm ratcheting combination wrench built for professional tradespeople who need reliable torque application in tight spaces. The wrench features a 15-degree offset box end with a 12-point configuration, allowing engagement on fasteners from multiple angles. Overall length is 7 inches, and the chrome finish over steel construction provides corrosion resistance for long service life. The ratcheting mechanism eliminates the need to reposition the wrench on each stroke, improving efficiency during repetitive fastening tasks. Tether-capable design supports tool-tethering programs required in elevated or restricted work environments.

This wrench is suited for mechanical, electrical, plumbing, and HVAC installation and maintenance work where metric fasteners are standard. The straight handle and 15-degree head offset make it practical for engine compartment work, panel installations, and equipment service. The 12-point box end engages hex fasteners securely and reduces the risk of rounding. At 7 inches overall, it fits most standard toolboxes and pouch organizers used in the field.

Installation Notes

This wrench is a hand tool for use by licensed mechanics, HVAC technicians, electricians, and plumbers. Before servicing any equipment, de-energize electrical circuits, shut off gas or fluid supply lines, and follow all applicable safety lockout/tagout procedures. Do not use the wrench as a striking tool or extend the handle with a cheater bar, as this can damage the ratcheting mechanism and create a safety hazard. Inspect the ratchet mechanism before each use to confirm smooth operation.
