Proto 1-1/2" Drive Impact Socket w/ 3-7/8" Opening Size

The efficient TorquePlus design featured in the 1-1/2" Drive Impact Socket w/ 3-7/8" Opening Size guarantees quick and easy socket engagement to the fastener flats, rather than the corners. With its radius-corner design, this impact socket minimizes slippage as it shifts the contact area and stress away from the fastener corners and distributes the contact stresses over a large area of the socket. This socket also includes a side locking hole.
