The APEX 81761 is a long-pattern combination wrench designed for professional use in tight or hard-to-reach fastener applications. Built from alloy steel, this 13MM wrench features a 6-point box end offset at 15 degrees to improve access in confined spaces. The off-corner loading design on both ends delivers a stronger grip on fasteners, reduces fastener rounding, and transfers significantly more torque compared to standard on-corner contact designs. Size markings are stamped directly into the beam for permanent, easy identification. At 6.94 inches in length and 0.18 pounds, it balances reach with control for repetitive fastener work.
The 81761 suits residential and commercial mechanical work across HVAC, plumbing, and general equipment service. The long-pattern length is especially useful when technicians need additional leverage on stubborn fasteners or need to reach past obstructions in equipment cabinets, mechanical rooms, or utility chases. The 13MM size covers a wide range of metric fasteners found on equipment panels, brackets, and fittings commonly encountered in trade service work.
Designed as a standard long-pattern combination wrench for use with 13MM metric fasteners across a wide range of trade and mechanical service applications.
This wrench is used by HVAC technicians, plumbers, electricians, and general mechanical tradespeople for fastener installation and removal. Always ensure the wrench is fully seated on the fastener before applying torque to avoid slippage or rounding. Do not extend the handle with a pipe or cheater bar beyond the intended design. Inspect the wrench for cracks or deformation before use and replace if damaged.
