The Bosch Driven Socket Adapter helps to add versatility by converting a driver with a 1/4" quick change hex to a socket wrench. This allows the user to use sockets for driving nuts, bolts and external hex head screws. The socket adapter clicks into the socket to help provide a tight fit for better fastener grip. This impact-rated accessory absorbs torque peaks to reduce stress on the fastener. This allows it to handle a new generation of higher torque impact drivers. The bit features clear head-type markings (or laser markings) that are easy to read and won’t rub off with repeated use.
