Wera 780B/1 3/8" Square Drive to 1/4" Hex Screwdriver Bit Holder

The Wera 780B/1 is a 3/8" square drive to 1/4" hex bit holder designed to extend the versatility of your socket set by allowing standard screwdriver bits to be used with a 3/8" drive ratchet or torque wrench.

Manufactured to DIN ISO 1173-C 6.3, this adaptor accepts any 1/4" hexagon shank bit from Wera's connecting series 1 range. The ball stop groove ensures bits are securely retained during use, reducing the risk of bits dropping or disengaging mid-task.

This type of socket adaptor is particularly useful for contractors and tradespeople working in confined spaces where a dedicated screwdriver isn't practical, or when driving fasteners that require the controlled torque of a ratchet. It bridges the gap between your socket set and your bit collection in a compact, reliable format.

• Converts 3/8" square drive to 1/4" hex for use with standard screwdriver bits
• Compatible with 1/4" hexagon shank bits to DIN ISO 1173-C 6.3
• Ball stop groove securely retains bits during use
