Professional Impact Universal Joint Set for Difficult Access Applications

The Britool Hallmark 3 Piece Impact Universal Joint Set is designed to provide professional mechanics and engineers with improved access when working in confined spaces or on awkwardly positioned fasteners. Covering the three most popular square drive sizes—1/4", 3/8" and 1/2"—this versatile impact UJ set allows sockets to articulate around obstructions while maintaining maximum strength and reliability.

Manufactured from premium heat-treated Chromium-Molybdenum (Cr-Mo) steel, these heavy-duty universal joints are specifically engineered to withstand the high torque generated by pneumatic air tools, cordless impact wrenches and other professional impact equipment.

Heavy-Duty Cr-Mo Construction

Each universal joint is forged from heat-treated Chromium-Molybdenum steel, providing exceptional toughness, impact resistance and long service life under demanding workshop conditions. Finished with a durable black phosphate coating, the joints offer excellent resistance to corrosion, helping maintain performance and appearance even after prolonged professional use.

Designed specifically for impact applications, they provide the strength required for high-torque fastening without compromising durability.

360° Swivel for Maximum Accessibility

The 360-degree articulated ball joint allows sockets to operate at multiple angles, making it significantly easier to reach fasteners hidden behind suspension components, engine assemblies, chassis members and other obstructions.

Each universal joint incorporates a spring-loaded retaining ball, ensuring sockets remain securely attached during use while allowing quick and easy socket changes.

Covers the Three Most Popular Drive Sizes

The set includes:

• 1/4" Drive Impact Universal Joint
• 3/8" Drive Impact Universal Joint
• 1/2" Drive Impact Universal Joint

Each joint is laser-etched with the Britool Hallmark logo and part number for quick identification in busy workshop environments.

Organised EVA Foam Storage

Supplied in a premium EVA foam tool control tray, each universal joint has its own dedicated location, keeping your toolbox organised while making missing tools instantly visible. The tray fits neatly into professional toolboxes, roll cabs and top boxes for efficient workshop organisation.

• Engine bays

• Steering components
• Exhaust systems
