Proto J1182-A Offset Box End Wrench 3/8 X 7/16 in 6 Pt

Product Description

The PROTO J1182-A is a double-end offset box end wrench designed for fastener work in confined or angled spaces. The offset head geometry provides clearance over obstructions while keeping both ends in contact with fasteners for reliable torque transfer. Sized at 3/8 inch on one end and 7/16 inch on the other, this wrench covers two of the most common fastener sizes found in HVAC equipment, plumbing fixtures, and mechanical assemblies. The 6-point box end design grips flat-to-flat on hex fasteners, reducing rounding compared to open-end configurations. Constructed from steel with a polished finish, it is built for repeated use under trade conditions.

This wrench suits residential and light commercial mechanical work where a standard straight wrench cannot reach due to panel flanges, mounting brackets, or tight equipment enclosures. HVAC technicians, plumbers, and pipefitters commonly reach for offset box end wrenches when servicing air handlers, fan assemblies, hydronic components, and valve packing nuts. The dual-size configuration reduces the number of tools needed in a tight workspace.

Compatibility

Designed as a standard offset box end wrench for use with 3/8 inch and 7/16 inch hex fasteners commonly found in HVAC, plumbing, and general mechanical applications.

Installation Notes

No power-down procedure is required for hand tool use, but always de-energize or isolate mechanical systems before loosening fasteners on live equipment. Confirm fastener size before applying torque to avoid head damage. This wrench is intended for hand torque only and should not be used with a cheater bar or impact driver.
