3/8"SD Original Britool England Standard Hexagon Impact Socket range 8-19mm (V1)

These original Britool Hallmark 3/8" Drive Impact Sockets were manufactured in the UK prior to the closure of the Britool factory, making them increasingly rare and highly sought after by professionals and collectors alike.

Forged from premium Chrome Molybdenum Alloy steel for superior strength, these sockets are designed for use with high-power pneumatic and impact tools. Each socket features Britool’s 6-point hexagon Stress Relief Drive, allowing higher torque loads to be applied while reducing fastener damage and rounding.

For secure and safe operation, every socket incorporates ball retaining grooves on each face of the square drive for a positive fit with all 3/8" drive accessories, along with a cross-drilled hole for optional pin and ring retention when used on impact wrenches.

Due to the UK manufacturing plant having closed several years ago, availability is now limited, making this a rare opportunity to obtain genuine British-made Britool tooling.

Available sizes:
Standard depth – 8mm to 19mm (while stocks last).

Please note: Images are for illustrative purposes only and may show a different size. You will receive the socket size selected at the time of order.
