Apex 81778 Long Pattern Combination Wrench 13/16 in

Product Description

The APEX 81778 is a long-pattern combination wrench with a 6-point box end, sized at 13/16 inch and built for trade use in mechanical, HVAC, and general maintenance applications. Forged from alloy steel with a durable finish, the wrench weighs 0.53 pounds and measures 11.827 inches in overall length. The off-corner loading geometry on both the box and open ends grips fastener flats rather than corners, reducing rounding under load and delivering increased torque transfer. Sizes are stamped directly into the beam for permanent identification without labels or stickers.

The long-pattern length gives technicians additional reach and leverage in confined or deep-access fastener locations, making it a practical choice for equipment panels, pipework fittings, and mechanical assemblies. The box end is offset 15 degrees to improve clearance when working in tight spaces. Suitable for residential and commercial service work across HVAC, plumbing, and general mechanical trades where a reliable, full-size combination wrench is required.

Installation Notes

This wrench is a hand tool installed and used by licensed technicians and experienced tradespeople across HVAC, plumbing, and general mechanical service. Always select the correct wrench size for the fastener to avoid rounding. De-energize electrical systems and shut off fluid or gas supplies before breaking fastener connections on live systems.
