GEARWRENCH 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. The 10 piece 1/4" Drive 6 Point SAE Deep Length Socket Set includes sizes: 3/16", 7/32", 1/4", 9/32", 5/16", 11/32", 3/8", 7/16", 1/2", & 9/16" and includes a socket rail for storage & organization.
