Professional XZN Spline Impact Socket Set for Automotive & Engineering Applications

The Britool Hallmark 10 Piece 1/2" Drive XZN Spline Impact Socket Set is engineered for professional mechanics, automotive technicians and engineers who require reliable performance when working with XZN (Triple Square) fasteners. Manufactured from premium Chromium-Molybdenum (Cr-Mo) steel, these heavy-duty impact sockets are built to withstand the high torque generated by impact wrenches, pneumatic air tools and cordless power tools.

Designed for demanding workshop environments, this comprehensive XZN socket set is ideal for servicing engines, transmissions, suspension components, drive systems and other applications where spline fasteners are commonly used.

Heavy-Duty Chromium-Molybdenum Construction

Each socket is precision-machined from heat-treated Chromium-Molybdenum steel, providing outstanding impact resistance, toughness and long service life. The accurately formed 12-point XZN (Triple Square) profile delivers maximum contact with the fastener, helping to reduce wear, minimise slipping and transfer torque more efficiently than poorly fitting alternatives.

With a 60mm overall length, each socket provides excellent accessibility when working in recessed or difficult-to-reach locations.

Comprehensive M4–M20 Size Range

The set includes ten of the most commonly used XZN sizes:

M4, M5, M6, M8, M10, M12, M14, M16, M18 and M20

Each socket is permanently laser-etched with the Britool Hallmark logo and part number, allowing quick identification even after years of workshop use.

Organised EVA Foam Storage

Supplied in a high-quality EVA foam tool control tray, every socket has its own dedicated location, helping to keep 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.
