Crescent CCW21-05 Combination Wrench 10MM 12 Point

Product Description

The CRESCENT CCW21-05 is a 10MM combination wrench designed for professional use in mechanical, HVAC, plumbing, and electrical trade work. It features an open end on one side and a 12-point box end on the other, giving technicians two engagement options in a single tool. The wrench measures 6.22 inches in overall length and is forged from alloy steel with a full polish chrome finish that resists corrosion and makes cleanup straightforward. At 0.11 pounds, it is lightweight enough for extended use without fatigue. This is a metric tool sold individually.

The CCW21-05 is suited for residential and commercial service calls where 10MM fasteners appear frequently — including equipment panels, mounting brackets, and component assemblies across HVAC, plumbing, and electrical systems. The 12-point box end allows engagement in tight spaces where swing arc is limited, while the open end speeds access to fasteners with more clearance. Trade professionals keeping a metric wrench set on the truck will find this a practical single-size addition or replacement.

Key Features

• 10MM metric size fits common fasteners found across HVAC, plumbing, and electrical equipment
• 12-point box end allows 30-degree swing increments for use in confined spaces
• Open end provides fast engagement when clearance allows
• Alloy steel construction for durability under torque loads
• Full polish chrome finish resists corrosion and simplifies cleaning
• 0-degree offset on the open end for flat, in-line fastener access

Compatibility

Designed for use with 10MM metric fasteners across a wide range of residential and commercial trade applications. Suitable as a direct replacement or single-wrench addition to any metric combination wrench set.

Installation Notes

Combination wrenches are hand tools used by licensed HVAC technicians, plumbers, and electricians across service and installation work. Always power down or shut off the system before loosening or tightening fasteners on live equipment. Inspect the wrench for cracks or damage before applying torque — do not use a damaged wrench. Keep chrome-finished tools dry and stored properly to maintain the finish and extend service life.
