CMMT99103 4.5mm 1/4 In. Drive 6-Point Deep Socket, Metric Alloy Steel

The Craftsman CMMT99103 is a precisely machined 4.5mm deep socket designed for tight-fit applications where standard sockets fall short. Built from high-grade alloy steel and finished with a durable polished chrome coating, this metric socket delivers reliable performance in automotive, HVAC, appliance repair, and industrial settings. The deep-well design reaches recessed fasteners in confined spaces, helping you complete repairs faster and with greater confidence.

Whether you're a professional mechanic or a DIY enthusiast, this socket combines robust construction with a compact footprint. The alloy steel resists wear and deformation, extending the life of your toolbox. Its 6-point drive geometry ensures a secure grip on bolts, reducing the risk of rounding and slippage while maximizing contact with fasteners.
