CMMT44297 Deep Socket, 21mm, 3/8 In. Drive, 12 Point

This Craftsman 21mm x 3/8 in. drive metric deep socket is an essential tool for mechanics, automotive technicians, and DIY enthusiasts who need reliable fastener access. Deep sockets reach fasteners in confined spaces where standard sockets fall short, making them ideal for engine work, machinery maintenance, and tight assembly applications. The 12-point configuration provides better grip and turning leverage in restricted areas, while the robust construction ensures durability through years of demanding use.

The laser-etched size marking on this socket remains visible even when covered in grease or used in low-light conditions, allowing you to quickly identify the correct tool without hesitation. The permanent marking resists chipping, fading, and corrosion, so your identification stays legible throughout the socket's working life. Designed to withstand the rigors of daily use, this socket maintains reliable performance in automotive repairs, machinery maintenance, and home improvement projects.
