Crescent CDS40N 10MM Metric Socket 3/8 Drive 12 Point

Product Description

The CRESCENT CDS40N is a 10MM metric socket built for professional use in hand-tool applications across mechanical, HVAC, plumbing, and electrical trades. Constructed from alloy steel with a full polish chrome finish, this socket resists corrosion and withstands repeated torque cycles in demanding service environments. It features a 12-point drive configuration and accepts a 3/8 inch drive ratchet or breaker bar. The overall length is 0.94 inches, making it a compact fit for tight fastener access. Part markings are hard stamped directly into the socket body for lasting identification even in greasy or dirty field conditions.

This socket is suited for residential and commercial service work where metric fasteners are standard. Common applications include equipment assembly, HVAC unit servicing, motor mounting, panel work, and general mechanical repair. The 10MM size is one of the most frequently used metric sizes in light-duty and medium-duty mechanical work, and the 3/8 inch drive sizing balances torque capacity with tool accessibility in confined spaces.

Installation Notes

This socket is installed by hand-tool technicians across multiple trades. Ensure the socket is fully seated on the fastener before applying torque to avoid rounding. Inspect the socket and drive tool for wear or cracks before use on high-torque fasteners. Follow applicable torque specifications for the equipment being serviced as defined by the equipment manufacturer.
