Wera 784B/1 3/8" Square Drive to 1/4" Hex Screwdriver Bit Holder

The Wera 784B/1 is a professional 3/8" square drive to 1/4" hex bit holder designed to bridge the gap between socket drive tools and hexagon screwdriver bits. This precision-engineered adaptor features a quick-release chuck for rapid bit changes, making it ideal for tradespeople who need to switch between ratchet work and precision screwdriving tasks efficiently. Manufactured to exacting German standards, this 43mm adaptor converts standard 3/8" square socket drives into a 1/4" hexagon bit holder compatible with DIN ISO 1173-C 6.3 bits. The quick-release mechanism ensures bits are held securely during use whilst allowing single-handed operation when changing between different bit types. The ball stop groove design provides positive retention within 3/8" drive tools, preventing accidental disconnection during operation. This makes the adaptor particularly suitable for use with ratchets, breaker bars, and torque wrenches where stability and reliability are essential. The compact 43mm length maintains good access in confined spaces whilst providing sufficient leverage for controlled fastening work.
