The Wera 784B/1 is a 3/8" square drive to 1/4" hex screwdriver bit holder, designed to convert a 3/8" square drive ratchet or socket wrench for use with standard 1/4" hexagon shank screwdriver bits. The adaptor features a quick-release chuck for rapid bit changes without interrupting workflow — ideal for tradespeople switching between fastener types on site. The 1/4" hexagon drive conforms to DIN ISO 1173-C 6.3, ensuring compatibility with a wide range of standard screwdriver bits, including those from Wera's connecting series 1. A ball stop groove is incorporated into the design to provide secure retention within the socket drive, reducing the risk of the adaptor working loose during use. This makes the 784B/1 a practical addition to any socket set where screwdriving capability is needed alongside conventional socket work.
