Wera 784A/1 1/4" Square Drive to 1/4" Hex Screwdriver Bit Holder

The Wera 784A/1 is a 1/4" square drive to 1/4" hex bit holder designed to convert a square drive ratchet or torque wrench into a power bit-compatible tool, bridging the gap between socket drive systems and screwdriving applications. Fitted with a quick-release chuck, the adaptor allows for rapid bit changes without interrupting workflow — a practical advantage when switching between fastener types on the job. It accepts screwdriver bits with a 1/4" hexagonal drive conforming to DIN ISO 1173-C 6.3, ensuring broad compatibility with standard hex shank bits from Wera's connecting series 1 and beyond. The integrated ball stop groove provides a secure, positive connection between the adaptor and the square drive tool, reducing the risk of the adaptor working loose during use. At 30mm in length, it adds minimal projection, keeping the overall setup compact and manageable in tighter workspaces. This adaptor is ideal for contractors and tradespeople who regularly switch between socket work and screwdriving tasks, allowing a single ratchet to serve both functions without the need for a separate bit driver.
