3/8"SD Britool England Metric Bi-Hexagon Flare Crow Foot Wrench MCFBM 9-21mm

This range of 3/8" Square Drive Crowfoot Wrenches were manufactured in the original Britool UK production facility prior to its closure, making these tools exceptionally rare and increasingly difficult to source.

Produced from high-quality alloy steel, each crowfoot features a bi-hexagon (12-point) profile designed to maximise torque application while reducing the risk of fastener damage. The crowfoot design allows access to fasteners in confined or obstructed areas where conventional spanners or sockets cannot be used.

Each piece is stamped with original Britool branding, including the Britool Hallmark “B” logo, part reference, and size, confirming authenticity and British manufacture.

Offset dimensions:
The distance from the centre of the square drive to the centre of the bi-hexagon crowfoot ranges from 14mm (sizes 9mm) up to 22mm (sizes 21mm).

A superb opportunity to acquire genuine UK-made Britool tooling, ideal for professional use, restoration work, or serious tool collectors.

Limited sizes available from 9 - 21mm.  Some AF Imperials sizes also available in this original England made design.

Please note that the images used are to show overall look and design of this range of crowfoot and you will receive the size as per your order.
