3/8" Drive Standard & Deep Impact Socket Sets 6-Point Profile Britool Hallmark

 The Britool Hallmark 3/8" Impact Socket Set Twin Pack combines both standard and deep sockets in one professional-grade solution, ideal for demanding workshop and automotive applications. Manufactured from premium Chromium Molybdenum steel, these sockets are engineered to withstand the high torque loads generated by pneumatic air tools and cordless impact wrenches.

Each set includes a comprehensive size range from 6mm through to 24mm in both standard and deep profiles, ensuring maximum versatility across a wide variety of fastening tasks. All sockets are heat treated to deliver exceptional strength, durability, and long service life under repeated impact use.

Featuring Britool’s Stress Relief Drive system, the sockets allow higher torque to be applied while reducing stress on fasteners, helping to minimise rounding and damage. The six-point hexagon profile ensures positive engagement, while precision-machined ball retaining grooves on each face of the square drive provide a secure fit with all 3/8" drive accessories. A cross-hole in each socket allows for optional pin and ring retention when used on impact tools.

The twin sets are supplied neatly organised in their own Tool Control EVA foam tray, designed to fit directly into a standard toolbox drawer, keeping tools secure, visible, and easy to locate. Each socket is laser marked with the Britool Hallmark logo and part number for quick identification and professional tool control.  Individual sockets are also available separately as and when replacements are needed.

The Britool Hallmark guarantee covers against defective materials and/or workmanship when used for the purpose for which they were designed and for the expected life of the tool. In the unlikely event that a product fails during normal use, it will be repaired or replaced. The guarantee does not extend to fair wear & tear, moving parts such as ratchet mechanisms or consumable items such as bits and repair kits.
