Crescent CCW3-05 Combination Wrench 3/8 Inch 12 Point

Product Description

The CRESCENT CCW3-05 is a 3/8-inch combination wrench designed for fastener work in mechanical, plumbing, electrical, and HVAC service environments. One end is an open-end configuration; the other is a 12-point box end, giving technicians two drive options in a single tool. The wrench measures 6.22 inches in overall length and is constructed from alloy steel with a full polish chrome finish that resists corrosion and wipes clean easily. At 0.135 pounds, it is light enough for overhead or confined-space work without sacrificing rigidity. This is an SAE-sized tool suited for standard inch-measurement fasteners.

This wrench is a standard hand tool used across residential and light commercial service calls. HVAC technicians, plumbers, electricians, and pipefitters reach for a combination wrench when working on equipment panels, access covers, pipe hangers, junction boxes, and mechanical connections that require a precise fit. The 3/8-inch size is commonly needed on smaller fasteners found on equipment controls, electrical enclosures, and condensate pan hardware. The zero-degree offset on the open end keeps the tool flat against fastener surfaces in tight layouts.

Key Features

• 3/8-inch SAE open end with zero-degree offset for flush fastener access
• 12-point box end provides more contact angles in confined spaces
• Alloy steel construction for durability under torque loads
• Full polish chrome finish resists corrosion and simplifies cleaning
• Compact 6.22-inch length suits tight service environments
• Lightweight at 0.135 pounds for extended use without fatigue

Compatibility

Designed for use with 3/8-inch SAE fasteners across a wide range of residential and commercial mechanical, electrical, and plumbing service applications.

Installation Notes

Always de-energize or shut off the relevant system before working on fasteners near electrical components, gas lines, or pressurized piping. Confirm fastener size before applying torque to avoid rounding. Use the box end when space allows for maximum contact on the fastener head. Inspect the wrench for cracks or chrome peeling before each use and retire any damaged tool from service.
