USAG 1/4" Drive Fractional Socket Set (with Foam module tray)(MODM.RU12) - compact module tray with 12 USAG fractional sockets (1/8" - 9/16"). Mix and match with the USAG 3/8" and 1/2" drive fractional socket module sets (see photo). Can be used openly in a tool box/trolley with other module and case sets or stored in a Facom/USAG small MBOX case for "grab and go" use in the field. USAG sockets have a more pronounced knurl for easier grip than Facom sockets (see photo). The cutout in the foam module tray will accommodate any of the USAG/Facom PICO sets.
