1/2"SD Impact Socket Set 8-36mm + 3/8"SD Set 6-24mm Bundle From Britool Hallmark

This Britool Hallmark Impact Socket Set Bundle combines two comprehensive ranges of professional-grade impact sockets in both 1/2" drive (8–36mm) and 3/8" drive (6–24mm), covering virtually all common fastening applications in automotive, industrial, and workshop environments.

Manufactured from premium Chromium-Molybdenum (Cr-Mo) steel and heat treated for maximum durability, these sockets are engineered for use with air and power impact tools. Britool’s advanced Stress Relief Drive system increases torque capacity while reducing stress on fasteners, helping to minimise rounding and damage.

All sockets feature a 6-point hexagon profile for secure engagement and improved torque transfer. A ball retaining groove in the square drive ensures a positive fit with compatible accessories, while a cross-drilled side hole allows optional use with a pin and ring retention system when required.

Each socket is laser marked with the iconic Britool Hallmark logo and part number for easy identification and workshop traceability. The sets are supplied in precision-cut EVA tool control foam trays, designed to fit directly into toolbox drawers, keeping tools organised and making missing sockets instantly visible.
