Apex 81670 Long Pattern Combination Wrench 13mm

Product Description

The APEX 81670 is a 13mm long pattern combination wrench built for professional trade use in tight or deep-access applications. It features a 12-point box end with an offset profile that improves clearance in confined spaces. The open end uses an off-corner loading design that increases grip on fasteners, reduces rounding, and delivers up to 25% more torque compared to standard open-end geometry. Constructed from premium alloy steel with a bright full-polish chrome finish, this wrench is engineered for durability and corrosion resistance in daily service work.

The 81670 is suited for mechanical and maintenance work across HVAC, plumbing, electrical, and general equipment service. The long pattern handle provides extra leverage on stubborn fasteners, making it a practical choice when working on equipment panels, pipework, conduit fittings, and structural connections that require a 13mm fastener. The large size stamp on the open end allows quick identification in a tool bag or on a crowded work surface.

Key Features

• 13mm 12-point offset box end for improved access in confined spaces
• Off-corner loading open end reduces fastener rounding and increases torque capacity by up to 25%
• Long pattern handle delivers extra leverage over standard-length combination wrenches
• Premium alloy steel construction for strength under high-torque use
• Bright full-polish chrome finish for corrosion resistance and easy cleaning
• Large size stamp on open end for fast identification

Compatibility

Designed as a standard 13mm combination wrench for use with metric fasteners in HVAC, plumbing, electrical, and general mechanical service applications.

Installation Notes

This wrench is intended for use by qualified trades professionals working on mechanical systems and equipment. Always ensure the correct wrench size is matched to the fastener before applying torque to avoid rounding. De-energize and isolate equipment before performing any service work involving tool access to live panels or pressurized systems. The offset box end should be seated fully on the fastener before applying force.
