Proto J1230MBASD Combination Wrench 30 Mm Offset

Product Description

The PROTO J1230MBASD is a 30 mm combination wrench built for professional trade use in industrial, mechanical, and maintenance applications. It features a 15-degree offset head angle that provides clearance in tight or obstructed fastener locations where a flat wrench cannot seat properly. The wrench measures 15.86 inches overall length and is constructed from corrosion-resistant steel. It is tether capable, making it suitable for work at height or in drop-hazard environments where tool retention is required. Licensed tradespeople, millwrights, and industrial mechanics will find this wrench appropriate for heavy fastener work that demands a full-size, non-ratcheting combination design.

This wrench is designed for use in industrial facilities, construction sites, and mechanical rooms where 30 mm fasteners are common. The straight handle and offset box end allow access to recessed or partially obstructed bolt heads. The tether-capable design meets job site safety requirements for elevated work platforms and overhead maintenance tasks. It is appropriate for use in HVAC equipment installation, heavy mechanical assembly, and general industrial maintenance where a reliable, full-size metric combination wrench is required.

Installation Notes

This wrench is intended for use by qualified tradespeople including millwrights, pipefitters, HVAC technicians, and industrial mechanics. Always de-energize and lock out equipment before performing fastener work on mechanical or electrical assemblies. When using this wrench in elevated work environments, attach the tether anchor point to an approved tool lanyard to meet site drop-prevention requirements. Inspect the wrench for wear or deformation before each use and do not apply extension bars or pipe cheaters to the handle.
