The CRESCENT CSWS11M is an 11-piece standard socket set built for professional trade use in mechanical, HVAC, plumbing, and electrical service work. The set features a 3/8-inch drive and 12-point socket geometry, allowing engagement on both hex and double-hex fasteners in tight or awkward positions. Sockets are constructed from chrome-finished steel, providing corrosion resistance and a clean surface that is easy to wipe down on the job. Socket depths range from 8.00 mm at the minimum to 19.00 mm at the maximum, giving technicians coverage across a practical range of fastener sizes without switching drive sizes.
This socket set is suited for residential and light commercial service environments where a compact, general-purpose 3/8-inch drive set is the workhorse of the toolbox. It is appropriate for HVAC technicians torquing equipment panels and access covers, plumbers working fixture and valve hardware, and electricians securing enclosure and panel fasteners. The 11-piece count keeps the set organized and portable for van or bag carry without a dedicated case.
Designed for use with standard 3/8-inch drive ratchets, extensions, and breaker bars. Compatible with any 3/8-inch drive tooling conforming to standard square-drive dimensions.
Sockets should be fully seated on the drive before applying torque to prevent rounding the drive tang or the fastener. Inspect each socket for cracks or deformation before use, particularly after high-torque applications. Do not use hand sockets with impact drivers unless the sockets are rated for impact use. Follow applicable trade codes and manufacturer torque specifications for the equipment being serviced.
