3/8" Drive Metric Allen Key / Hexagon Bit Socket Range From Britool Hallmark

Manufactured from Chrome Vanadium steel, these bit sockets are available in metric sizes from 3mm to 10mm. The hexagon bits are secured into the socket base with a grub screw, making them replaceable if they become worn. This design treats the bit as a consumable component for long-term serviceability.

The 3/8-inch square drive includes a ball retaining groove on every face to maintain a positive fit with ratchets and extensions. Developed in the 1980s for professional technicians, the Hallmark range features the Britool hallmark stamped on every tool as a mark of its manufacturing standard.
