Crescent CDDS40N Deep Hand Socket 3/8 Dr 10mm 6-pt

Product Description

The CRESCENT CDDS40N is a deep hand socket designed for use with 3/8 inch drive ratchets and extensions. It fits a 10 mm fastener and features a 6-point hex drive profile for maximum contact with fastener flats, reducing the risk of rounding. The socket measures 2.5 inches overall length, making it suitable for reaching recessed or deeply set fasteners. Constructed from alloy steel with a nickel chrome plated finish, it resists corrosion and wear under regular shop and field use. This socket meets ASME B107.1-2002 standards and is rated for metric applications.

This deep socket is well suited for automotive, HVAC, plumbing, and general mechanical work where standard-length sockets cannot reach fastener heads set below a surface or within a confined cavity. Technicians use it in underhood work, equipment maintenance, and panel assembly wherever a 10 mm hex fastener requires extra reach. The 3/8 inch drive size is common across mid-range hand tool sets used by trade professionals in both residential and light commercial settings.

Key Features

• 6-point hex drive profile minimizes fastener rounding under torque

Compatibility

Designed as an OEM-style replacement deep socket compatible with standard 3/8 inch drive ratchets, extensions, and torque wrenches using a 10 mm hex fastener interface.

Installation Notes

This socket is installed and removed by hand using a compatible 3/8 inch drive ratchet or torque wrench. Ensure the drive tool is rated for the torque being applied before use. Inspect the socket for cracks or deformation before each use and replace if damaged. No power-down procedure is required, but always verify the work area is safe and fasteners are accessible before applying force.
