## Long description

Wera 784 A nut driver bit is a single-piece accessory with a 1/4" hexagonal shank and a total length of 30 mm, intended for driving and removing hex nuts and fasteners. The bit is compact and lightweight, compatible with 1/4" bit holders and interchangeable tool systems, and designed to be used with both hand tools and power drivers. Its 1/4" hex geometry conforms to common bit-holder standards and the driver end accepts a 1/4" square drive via the supplied adapter and quick-release chuck for fast bit changes.
Advantages
The bit's single-piece construction provides accurate torque transfer and reduced play between driver and fastener. Its compact 30 mm length allows access in confined spaces while maintaining stability during use. The included square-to-hex adapter and quick-release chuck simplify installation and removal in compatible holders, speeding up work on assembly, maintenance, or repair tasks. Lightweight construction makes it easy to carry in a kit or pocket without adding significant bulk.
Suitable for
 Driving and removing hex nuts and hex-head fasteners
 Use with 1/4" bit holders and interchangeable tool systems
 Assembly, maintenance and repair work in confined spaces
 Hand-tool and power-driver applications that accept a 1/4" hex drive

 Overall length: 30 mm
 Function: nut driver for hex nuts and fasteners
 Compatibility: fits 1/4" bit systems and adapters conforming to DIN ISO 1173-C 6.3
 Drive interface: supplied adapter converts 1/4" square drive to 1/4" hexagon

How to use
Select the appropriate bit holder or quick-release chuck that accepts a 1/4" hex shank. Insert the Wera 784 A bit into the holder until it locks or seats firmly. If using a square-drive tool, attach the supplied square-to-hex adapter to enable compatibility, then secure the bit in the quick-release chuck. Position the bit on the hex nut or fastener and apply steady pressure while turning with a hand tool or running the power driver at low speed to engage the fastener. Retract the bit from the fastener and release it from the holder when the operation is complete.
Usage recommendations
Use the bit within the torque limits of your driver and avoid excessive side loading. For repetitive or high-torque operations, verify compatibility with the power tool and consider using impact-rated bits when applicable. Keep the interface of the quick-release chuck clean and free of debris to ensure secure retention and smooth bit changes.
