Bosch Impact Tough™ 1/4 In. Thin-Wall Hex Sockets feature torque-absorbing construction and have been upgraded to work with 1/4 In. hex impact drivers. This impact-rated socket absorbs torque peaks to reduce stress on the fastener. It is enhanced to handle a new generation of higher torque impact drivers. The thin-wall construction enhances use in tight work areas, such as machinery or auto engines. Each socket is made of forged steel to reduce breakage, and it features laser-etched markings that are easy to read and won’t rub off with repeated use.
