Crescent CCW1-05 Combination Wrench 5/16 Inch Sae

Product Description

The CRESCENT CCW1-05 is a 5/16 inch SAE combination wrench built from alloy steel with a full polish chrome finish. It features a 12-point box end and an open end on the opposite side, giving technicians two drive options in a single hand tool. At 5.51 inches in overall length and weighing 0.09 pounds, this wrench is sized for tight-access fastener work common in HVAC equipment panels, plumbing fixture connections, and electrical enclosures. The open end is offset at 0 degrees for straightforward flat-surface engagement. This is a standard SAE-sized tool suitable for everyday trade use.

The CCW1-05 is used wherever a 5/16 inch SAE fastener needs to be driven or loosened in confined spaces. Its compact overall length makes it practical for working inside equipment cabinets, junction boxes, access panels, and mechanical assemblies where longer tools cannot reach. HVAC technicians, plumbers, and electricians routinely carry combination wrenches in this size range for service calls involving equipment covers, bracket hardware, and terminal connections.

Installation Notes

Combination wrenches are hand tools requiring no power source or special installation. Before servicing any equipment, follow lockout/tagout procedures and de-energize or shut off supply lines as required by applicable safety codes. Use the box end for initial breakaway and final torque, and the open end for intermediate spinning where access allows. Inspect the wrench for cracks or deformation before each use and do not use a cheater bar or extension on a standard combination wrench.
