3/8"SD Impact Hexagon 17Pc Socket Set from Britool Hallmark (V2) - MHMPSET17

The Britool Hallmark 3/8" Drive Impact Socket Set is crafted from premium Chrome Molybdenum Alloy steel for exceptional strength and durability, making it ideal for use with high-power pneumatic tools such as impact wrenches.

Each socket features a 6-point hexagon Stress Relief Drive, enabling higher torque loads while minimising fastener damage. Ball retaining grooves on each face of the square drive ensure a secure fit with all 3/8" accessories, and a cross-drilled side hole allows optional use with a pin-and-ring retention system for added safety.

This set contains standard depth metric sizes 6–22mm, supplied on a socket rail for easy storage and organisation. While these sockets carry the modern “Marque of Skill” branding, they have since been superseded by the V3 design, which is now supplied individually or in foam tool sets.

Perfect for professional mechanics and workshops seeking a robust, organised, and reliable impact socket solution.
