## Summary description

The Wera 780 C/1 nut driver bit is designed for hexagonal fasteners. It features a shank size of 25.4 / 2 mm (1 / 2") and a length of 35 mm. Weighing 73 g, this bit is made in the Czech Republic, ensuring high quality and durability for professional use.

## Long description

The Wera 780 C/1 nut driver bit is an adaptor that converts a 1/2" square drive to accept 1/4" hexagon bits. Made in the Czech Republic, it is designed to fit hexagonal fasteners and to be used with bits that conform to DIN ISO 1173-C 6.3. The adaptor combines a 25.4 / 2 mm (1/2") square shank with a compact 35 mm overall length and a lightweight 73 g construction for convenient handling in professional environments.
Advantages
The adaptor provides secure engagement between a 1/2" drive tool and 1/4" hexagon bits, reducing slippage and wear on fasteners. Its short 35 mm length allows access in confined spaces while maintaining torque transfer efficiency. Being manufactured in the Czech Republic, the bit is produced to consistent quality standards suitable for regular workshop or industrial use.
Suitable for
Converting a 1/2" square drive socket or ratchet to use 1/4" hex bits
Working with hexagonal screws and nuts in machinery and equipment maintenance
Tasks that require a compact adaptor to access tight or recessed fasteners
Professional workshops and service technicians who use standardized bits
Key specifications

Drive input: 1/2" square
Shank size: 25.4 / 2 mm (1/2")
Overall length: 35 mm
Weight: 73 g

How to use
Insert a compatible 1/4" hex bit into the hex end of the adaptor until it seats securely. Fit the 1/2" square end into the corresponding tool, such as a ratchet, breaker bar or socket handle. Apply torque gradually, ensuring the bit and adaptor remain aligned with the fastener. For removal, reverse the procedure and inspect the adaptor and bit for wear before next use.
Usage recommendations
Use with bits that meet the DIN ISO 1173-C 6.3 specification and avoid excessive impact or extreme torque beyond the capability of the hex bit to prevent damage. Keep the adaptor clean and periodically inspect for rounded edges or cracks. Store with compatible bits to maintain readiness and to reduce the risk of corrosion or loss.
