JHW38903 - Williams - 9 pc 3/4" Drive SAE One-Piece Impact Hex Bit Driver Set

The Williams JHW38903 is a 9-piece 3/4" drive one-piece impact hex bit driver set in SAE, built to drive large hex-head and internal-hex fasteners with pneumatic or electric impact wrenches. Each driver is forged as a single piece no separate bit and holder to shear apart and specially heat-treated for impact use, so it holds up under high-torque work.

Chamfered ends start easily into the fastener, and the drive end has a pin-retention hole and groove for secure impact-wrench mounting. Sizes span 1/2" to 1-1/4", in a black industrial finish.
