Utilizing a 90-tooth gear for a 4° swing arc, this 83-piece mechanics tool set facilitates fastening in tight spaces. The sockets employ an off-corner loading design to reduce fastener rounding across ¼" (6.4 mm), 3/8" (9.5 mm), and ½" (12.7 mm) drive sizes. This collection meets ASME and ANSI specifications and includes a 20.25" (51.4 cm) x 13.5" (34.3 cm) x 2.0" (5.1 cm) foam storage tray with size markings for organization.
