Gearwrench 81771 Combination Wrench 3/8 Inch 15 Deg Offset

Product Description

The GEARWRENCH 81771 is a 3/8 inch combination wrench built for professional hand-tool use in HVAC, plumbing, electrical, and general mechanical service work. It features a 6-point box end with a 15-degree offset head angle, giving technicians better knuckle clearance when working in tight or recessed fastener locations. The wrench is machined from steel with a polished finish that resists corrosion, making it suitable for both shop and field conditions. Overall length is 6.5 inches, and the unit weighs approximately 0.11 pounds. Compliance with ANSI and ASME standards confirms dimensional accuracy and load ratings appropriate for trade use. A lifetime replacement warranty backs the tool against manufacturing defects.

The 81771 suits residential and light commercial service calls where 3/8 inch fasteners appear on equipment panels, pipe fittings, electrical enclosures, and mechanical assemblies. The 15-degree offset box end is particularly useful when working around obstructions or on recessed bolt heads that a straight wrench cannot reach cleanly. The open end provides fast engagement for run-down work, while the 6-point box end maximizes contact on the fastener flats to reduce rounding risk on worn hardware. This wrench is a standard carry item for HVAC service techs, plumbers, and electricians who keep a compact hand-tool kit on the truck.

Compatibility

Designed as a standard 3/8 inch SAE combination wrench suitable for general mechanical, HVAC, plumbing, and electrical service applications requiring an open-end and offset box-end tool.

Installation Notes

No power source or lockout is required for hand-tool use, but always de-energize electrical panels and shut off gas or water supply before working on live systems. Inspect the wrench for cracks or deformation before each use and replace if damaged. Apply force in the pull direction when possible to reduce slip risk, and confirm fastener size before applying torque to avoid rounding.
