Wera 780A/1 1/4" Square Drive to 1/4" Hex Screwdriver Bit Holder

The Wera 780A/1 is a precision-engineered adaptor designed to convert 1/4" square drive sockets for use with hexagonal screwdriver bits. This versatile connector allows tradespeople to use standard hex bits with square drive ratchets and torque wrenches, extending the functionality of existing tool collections. Manufactured to DIN ISO 1173-C 6.3 standards, this adaptor accepts bits with 1/4" hexagon drive, making it compatible with Wera's connecting series 1 and other standard hex bits. The compact 25mm length provides excellent access in confined spaces whilst maintaining full torque transfer between drive and bit. The adaptor features a ball stop groove mechanism that securely retains bits during operation, preventing accidental detachment whilst still allowing quick bit changes. This makes it particularly useful for automotive work, machinery maintenance, and assembly tasks where switching between socket and bit work is frequent. The robust construction ensures reliable performance across workshop, site, and mobile service applications.
