## Long description

The Wera 8790 HMC nut driver bit is a single hexagonal-driver insert designed for use with 1/2" (25.4 / 2 mm) hex shank tool holders. With a length of 37 mm, the bit provides a compact profile for tight spaces while delivering the torque transmission and fit accuracy required for repeated fastening operations. Constructed for durability and consistent engagement, this nut driver bit is suitable for both workshop and on-site tasks where a secure hex connection is needed.
Advantages
The Wera 8790 HMC offers precise hex engagement and reduced cam-out thanks to its machined tip and exact tolerances. Its compact 37 mm length allows access in confined areas where longer bits would be impractical. Manufactured from hardened materials and finished to resist wear, the bit ensures long service life and dependable performance under frequent use. The standard 1/2" hex shank provides compatibility with a wide range of sockets, holders and impact adapters.
Suitable for
 Automotive fastening and maintenance tasks
 Assembly and disassembly of machinery and equipment
 Workshop and professional repair jobs requiring a 1/2" hex drive
 DIY projects that need a compact, durable nut driver bit
Key specifications
 Shank style: Hexagonal 1/2" (25.4 / 2 mm)
 Working length: 37 mm
 Tip profile: Hex (nut driver)
 Material characteristic: hardened and wear-resistant steel
 Fitment: designed for secure engagement with hex fasteners
How to use
Insert the 1/2" hex shank into a compatible socket holder, ratchet, or impact adapter until it seats securely. Position the hex tip over the fastener and apply steady torque while maintaining axial alignment to minimize slippage. For repetitive or high-torque applications, ensure the holder and driver are rated for the applied load and inspect the bit routinely for wear or deformation.
Usage recommendations
Use the bit with tools and holders that match the 1/2" hex shank specification. Avoid lateral bending forces and do not use the bit if the tip shows significant rounding or wear. For high-torque or impact use, confirm compatibility with impact-rated holders and adapters to maintain safety and extend bit life.
