Proto JSBV-8S Ratcheting Box End Wrench Set 8 Pc Inch

Product Description

The PROTO JSBV-8S is an 8-piece ratcheting box end wrench set in inch sizes, covering a range from 7/32 in x 9/32 in up to 1 in x 1-1/8 in. Each wrench features a 15-degree offset head angle and a 12-point ratcheting box end, allowing controlled torque in confined spaces without removing and repositioning the tool. The black and chrome finish provides corrosion resistance during regular shop or field use. This set is suited for licensed mechanics, HVAC technicians, plumbers, and electricians who need a reliable, full-range inch wrench set for equipment maintenance and installation work.

This set is appropriate for residential and commercial service work where inch-measurement fasteners are standard. The 15-degree head offset provides knuckle clearance in tight quarters, making it practical for accessing fasteners on condensing units, air handlers, electrical panels, pipe hangers, and mechanical equipment. The included storage pouch keeps the set organized for transport to job sites. All eight wrenches are double-ended, effectively providing 16 size combinations from a single set.

Installation Notes

Ratcheting box end wrenches are intended for use by qualified trade professionals on mechanical, HVAC, plumbing, and electrical equipment. Always de-energize electrical systems and shut off gas or fluid supply before servicing any equipment. Inspect the ratcheting mechanism before each use and do not use the wrench as a cheater bar extension. Store in the included pouch to prevent jaw damage and maintain ratchet function.
