Proto J1220H-T500 Combination Wrench 5/8 Inch

Product Description

The PROTO J1220H-T500 is a 5/8 inch combination wrench built for professional tradespeople who work in environments where tool retention and corrosion resistance matter. The open end and box end are forged from steel with a chrome finish that resists corrosion and cleans easily between jobs. The box end features a 6-point design with a 15-degree offset angle, which helps clear obstructions and reduces knuckle clearance issues in tight spaces. At 9-13/32 inches overall length and 0.36 pounds, it balances reach with controlled torque. The wrench meets ASME B107.100-2010 standards and carries a lifetime warranty, making it a reliable choice for HVAC, plumbing, electrical, and general mechanical work.

This wrench is suited for residential and commercial service applications where fastener access in confined areas is routine. The 15-degree head offset allows access to recessed fasteners without removing adjacent components. The tether-capable design supports use in elevated work areas, overhead installations, or any jobsite where a dropped tool creates a safety hazard. Licensed tradespeople working on mechanical equipment, conduit supports, piping systems, and structural connections will find the 5/8 inch size a frequently used dimension in both SAE-fastened equipment and structural hardware.

• Meets ASME B107.100-2010 standard for combination wrenches
• Lifetime warranty coverage

Compatibility

Designed for use with 5/8 inch SAE fasteners across a wide range of mechanical, HVAC, plumbing, and electrical applications. Compatible with standard tether attachment systems for tool-retention compliance programs.

Installation Notes

A licensed mechanic or journeyman tradesperson should select the correct wrench size before applying torque to avoid fastener damage. Power down or de-energize equipment before working on any mechanical assembly that involves live electrical or pressurized components. Use appropriate personal protective equipment when working in elevated areas where tether attachment is required. Do not use extension bars or cheater pipes on a combination wrench, as this can exceed the tool design limits and cause failure.
