3/8"SD Hexagon (6 Point) Socket from Britool Hallmark - MHM range (V2) 6-24MM

These 3/8" drive sockets from Britool’s Hallmark MHM range offer precision and professional performance, forged from premium alloy steel to withstand rigorous workshop demands.

The 6-point hexagonal design ensures exact alignment with 3/8" drive fasteners, while ball retention grooves on each square drive face provide a secure, slip-free fit. Britool’s Stress Relief Drive system protects fasteners from damage and allows higher torque loads to be safely applied, meeting the performance standards expected by professionals.

Finished in a high-polished chrome mirror finish, each socket is stamped with the “The Marque of Skill” branding and the iconic Britool Hallmark logo, guaranteeing authenticity and quality.

This set is part of the MHM Version 2 (V2) range, with sizes 6mm to 24mm. As these sockets have since been replaced by the Version 3 (V3) range, availability is limited—making them a sought-after choice for collectors and professionals seeking the original design.

A matching deep-depth V2 socket range is also available for recessed fasteners.

Please note picture may be of a different size but you will receive the size you order.
