- EYE-D™ markings optimize size visibility, also providing SAE/metric differentiation
- Unique socket retention method, cold form ball recess, provides consistent secure retention of the socket to the drive tool eliminating the possibility of either a loose fit or tight fit
- Socket wall dimensions are optimized to provide strength while retaining access to restricted fasteners
- Manufactured from high alloy steel using the most up-to-date manufacturing process and heat treat for greater strength and durability

GEARWRENCH 3/8" drive sockets are manufactured from alloy steel for maximum durability and strength. Our off corner loading design reduces fastener rounding and the chamfered opening help guide the socket on to fasteners. Our sockets feature a double line (SAE) and knurled (metric) ring help easily identify standard and metric sockets.
