These Original Britool Industrial Whitworth Impact Sockets are genuine UK-manufactured tools produced at the renowned Britool Cannock factory before its closure. Designed for professional use with impact wrenches, pneumatic tools, and power tools, these sockets are now increasingly difficult to source and represent a rare piece of British engineering heritage.

Manufactured with a robust 6-point hexagon profile, the sockets provide secure engagement with Whitworth fasteners while delivering the durability required for high-torque applications.

Each socket incorporates Britool's Corner Relief Drive System, which positions contact away from the corners of the fastener and onto the flats, improving torque transfer, reducing stress concentration, and helping to minimise fastener damage under load.

Frequently Asked Questions

What sizes are available in these original Britool Industrial Whitworth impact sockets?
Two sizes are currently available: 5/8" Whitworth / 11/16" British Standard and 3/4" Whitworth / 7/8" British Standard. Both the Whitworth and corresponding British Standard sizes are marked on the sockets. This listing is for one individual socket in the size selected.
What is the difference between Whitworth and British Standard socket sizes?
Whitworth (BSW) and British Standard (BS/BSF) fastener systems use historical British sizing conventions where the stated spanner or socket size does not simply represent the measurement across the flats in the same way as modern AF sizing. These sockets are marked with both their Whitworth and corresponding British Standard sizes, helping users select the appropriate socket for older British fasteners.
What is the Britool Corner Relief Drive System?
Britool's Corner Relief Drive System is designed to transfer more of the turning force onto the flats of the fastener rather than concentrating it directly on the corners. This helps distribute torque, reduce stress on fastener corners and minimise the risk of rounding when working under demanding loads.
Are these genuine British-made Britool impact sockets?
Yes. These are genuine Britool Industrial sockets manufactured in England at the original Britool Cannock factory before its closure. They are discontinued new-old-stock tools, making remaining examples increasingly difficult to source for professional use, restoration work and Britool collections.
What applications are 3/4" drive Whitworth impact sockets suitable for?
These heavy-duty sockets are particularly useful for classic vehicle restoration, vintage engineering equipment, agricultural machinery, industrial machinery and older British equipment using Whitworth or British Standard fasteners. Their 3/4" square drive also makes them suitable for demanding professional workshop applications requiring compatible heavy-duty impact equipment.
Will these original UK-made Britool sockets be available again once sold out?
Availability is limited to the remaining old stock. As these sockets were manufactured at the Britool Cannock factory before UK production ceased, further identical British-made replacements are unlikely to become available once the remaining sizes have sold.
