Gearwrench 81816 Combination Wrench 1-3/8 Inch 12-point

Product Description

The GEARWRENCH 81816 is a 1-3/8 inch combination wrench built for professional tradespeople who need reliable torque in tight service environments. The wrench features a 12-point offset head design that provides multiple contact points on fasteners, reducing the chance of rounding. Constructed from steel with a satin finish, it measures 19.96 inches overall and weighs 2.87 pounds. The corrosion-resistant construction meets ANSI and ASME standards, making it suitable for daily use in demanding shop and field conditions. A limited lifetime warranty backs the tool.

This wrench is suited for residential and commercial mechanical work where large-diameter fasteners are common. HVAC technicians, plumbers, pipefitters, and general mechanics will find the 1-3/8 inch head size appropriate for flange bolts, large fittings, and equipment mounting hardware. The offset head allows clearance when working in recessed or obstructed areas where a straight-head wrench cannot seat properly. The satin finish reduces glare and resists surface corrosion during extended storage or outdoor use.

Installation Notes

This wrench is a hand tool used by licensed tradespeople and experienced technicians across multiple trades. Always ensure the wrench head is fully seated on the fastener before applying torque to prevent slipping or fastener damage. When working near energized equipment, power down the system and follow applicable NFPA 70E or site-specific lockout/tagout procedures before using hand tools in the work area.
