Proto J1186M-A Offset Box End Wrench 12 Point Double End

Product Description

The PROTO J1186M-A is a double-end offset box end wrench built for professional trade use in mechanical, industrial, and maintenance applications. It features a 12-point box configuration on both ends, allowing engagement with hex fasteners from multiple angles. The offset design provides knuckle clearance when working in confined spaces or around obstructions. Constructed from steel with a polished finish, this wrench is suited for daily shop and field use by mechanics, pipefitters, millwrights, and general maintenance technicians who require a reliable non-ratcheting box end tool.

This wrench is used in residential, commercial, and industrial maintenance settings where a fixed box end is preferred over an open-end or combination wrench. The 12-point design allows easier fastener engagement in tight quarters where swing arc is limited. The offset angle between the handle and the wrench heads helps clear surrounding components, making it practical for engine work, pump assemblies, piping flanges, and structural fastener applications.

Compatibility

Designed as a standard double-end offset box end wrench suitable for use with 12-point hex fasteners in mechanical, industrial, and maintenance applications.

Installation Notes

This wrench is used by mechanics, pipefitters, and maintenance technicians working on bolted assemblies. Always ensure the wrench is fully seated on the fastener before applying force to prevent rounding. De-energize, depressurize, or lock out equipment before servicing fastened components per applicable safety and lockout/tagout procedures. Inspect the wrench for cracks or deformation before each use and replace if damaged.
