## Summary description

Wera 780 A 1/4" adaptor with a hex shank designed to accept 1/4" (6.35 mm) screwdriver bits. The adaptor has a 25.4/4 mm (1/4") shank size, 25 mm length, 13 mm diameter and weighs 14 g. It converts bit holders or drivers to a compatible hex-bit interface for hand or power tool use in assembly, repair and maintenance tasks.

## Long description

Wera 780 A 1/4" adaptor is a compact interface piece that converts a 1/4" (6.35 mm) square drive to a 1/4" hex bit holder. With a 25 mm overall length, 13 mm diameter and a lightweight 14 g construction, this adaptor allows the use of standard 1/4" hex screwdriver bits in tools or holders that accept a 1/4" square drive. The adaptor is compatible with bits conforming to the 1/4" hexagon drive format and includes a ball stop groove to secure bits during use.
Advantages
The adaptor provides a simple and reliable way to convert between square and hexagonal interfaces without altering the bit. Its compact dimensions and low weight make it suitable for handheld work and for use with power drivers where a short, rigid connection is required. The integrated ball stop groove improves retention of bits, reducing the risk of accidental disconnection during assembly, maintenance, or repair tasks.
Suitable for
 Assembly tasks requiring 1/4" hex bits with a square-drive tool
 Repair and maintenance work using handheld or powered drivers
 Situations where a short adaptor is needed for improved access or control
 Work with fastening systems that use 1/4" hexagon drive bits
Key specifications
 Drive conversion: 1/4" square drive to 1/4" hex bit
 Shank size: 1/4" (6.35 mm)
 Length: 25 mm
 Diameter: 13 mm
 Weight: 14 g
 Retention feature: ball stop groove
 Standard compatibility: 1/4" hexagon drive per DIN ISO 1173-C 6.3
How to use
Insert the 1/4" hex screwdriver bit into the adaptor until it engages with the ball stop groove. Fit the adaptor's 1/4" square drive into the holder or driver and ensure a secure seating before applying torque. Use with appropriate bits and tools rated for the required torque; the short length provides stable transfer of torque for common fastening operations.
Usage recommendations
Use the adaptor with bits that conform to the 1/4" hexagon drive specification and avoid exceeding the torque limits of the bit or driver. Keep the ball stop groove clean of debris to maintain reliable bit retention. Inspect the adaptor for wear or deformation before use and replace if damaged.
