Accessories

Impact Sockets

Radial carries a large stock of impact sockets. From small to large sizes, standard height or deep sockets, Allen, 4, 6, 8 or 12-point, everything is available from stock or on request.

Smart Sockets™

The RAD Smart Socket™ Series, patented impact sockets from 27 mm – 110 mm that are able to measure the actual torque applied to the bolted joint with a maximum deviation of 1%. The Smart Socket™ measures the actual torque on the bolt to within 1% and is no larger than a standard power socket.

Reaction Arms

Each RAD torque wrench is supplied with a suitable standard torque arm. Radial supplies special reaction arms for various applications. Some examples are high socket reaction arms, extended reaction arms or sliding reaction arms. Allen bolts are often used in diesel overhauls. Sliding reaction arms are an ideal solution for this work. Here, one allen bolt can be used to tighten or loosen the bolt, while the second allen bolt is used as a support point in an adjacent bolt.
