US PRO 7246 29 Piece 1 4 Inch Hex Drive Magnetic Impact Nut Driver Set Metric and Imperial

The US PRO 7246 29 Piece 1 4 Inch Hex Drive Magnetic Impact Nut Driver Set Metric and Imperial is a versatile fastening solution designed for speed, control, and convenience when working with power tools. Ideal for automotive, construction, fabrication, and general workshop use, this comprehensive set combines nut drivers, extensions, adaptors, and a bit holder into one practical kit.

Each nut driver is fitted with a copper sleeve containing an embedded hardened steel magnet, allowing nuts to be securely held during installation or easily retrieved from recessed or awkward locations. This feature significantly reduces dropped fasteners and improves efficiency, especially when working at height or in confined spaces. The drivers are colour coded to clearly distinguish between metric and imperial sizes, helping speed up size selection during repetitive tasks.

The set includes quick release magnetic extension bars in three useful lengths, providing improved reach while maintaining secure bit retention. Also supplied are socket adaptors for 1/4 inch, 3/8 inch, and 1/2 inch drive sockets, allowing standard sockets to be used with impact drivers. A magnetic bit holder completes the set, adding further versatility for mixed fastening jobs.

All components feature a universal 1/4 inch hex shank, making them compatible with impact drills, impact drivers, powered screwdrivers, quick release systems, and standard chucks. Manufactured from hardened steel, the set is built to withstand the demands of impact use while delivering reliable performance across a wide range of applications.
