The Britool Hallmark Universal Joint Socket Adapter is a professional-quality accessory designed to improve access when working on fasteners in confined or awkward positions. Manufactured from premium Chrome Vanadium steel with a high-polished chrome finish, these universal joints provide strength, durability, and smooth operation for professional workshop use.
A universal joint consists of two hinged yokes connected by a cross shaft, allowing the drive to articulate and transmit torque at an angle. This makes it ideal for reaching fasteners that cannot be accessed in a straight line, particularly within engine bays, machinery, and restricted workspaces.
Finished with the modern Britool Hallmark "The Marque of Skill" branding, these universal joints are available individually in the most popular square drive sizes.
