Britool Hallmark 3/8" Drive Slotted Bit Socket 6mm 7mm 8mm UK Made

These Britool Hallmark Slotted Bit Sockets are genuine UK-manufactured tools produced in the original Britool factory before its closure. Manufactured from high-quality chrome alloy steel, they provide the strength, durability, and precision expected from professional-grade British tooling.

Each socket features a fixed flat blade (slotted) screwdriver bit securely retained within the socket body using a roll pin. Designed for use with 3/8" drive ratchets, extension bars, and accessories, these sockets are ideal for workshop, engineering, and maintenance applications requiring higher torque than a conventional screwdriver can provide.

As discontinued UK-made Britool products, these sockets are now increasingly rare and available only in limited quantities.
