Frequently Asked Questions

What is included in the Britool Hallmark 40-piece impact tool twin pack?
This Britool Hallmark Twin Pack combines a 32-piece 3/8" drive standard and deep impact socket set with an 8-piece 3/8" and 1/2" drive impact extension bar set. Together they provide 40 professional impact-rated tools for automotive servicing, engineering, commercial vehicle maintenance and workshop applications.
What impact socket sizes are included in the 32-piece set?
The socket set contains 7mm through to 22mm in both standard and deep lengths, providing 16 metric sizes in each depth. All sockets have a 3/8" square drive and 6-point hexagon profile, giving excellent coverage for professional automotive and mechanical impact-wrench applications.
Can these Britool Hallmark sockets and extension bars be used with impact wrenches?
Yes. Both sets are manufactured from Chrome Molybdenum (Cr-Mo) steel and are designed for compatible pneumatic air impact wrenches, cordless impact wrenches and powered impact tools. Unlike conventional chrome hand sockets and extensions, these components are specifically intended for demanding impact applications.
What sizes are included in the Britool Hallmark impact extension bar set?
The 8-piece set contains four 3/8" drive impact extensions measuring 50mm, 100mm, 175mm and 250mm, plus four 1/2" drive impact extensions measuring 75mm, 125mm, 200mm and 300mm. This selection provides additional reach for recessed and difficult-to-access fasteners across automotive, engineering and heavy-duty workshop applications.
Why does the impact socket set include both standard and deep sockets?
Standard-depth impact sockets provide a compact solution for everyday fastening, while deep impact sockets offer additional reach for recessed nuts, longer studs and difficult-to-access fasteners. Having every size from 7-22mm in both standard and deep profiles gives professional mechanics greater flexibility without needing separate socket collections.
How are the Britool Hallmark impact sockets and extension bars stored, and can replacements be purchased?
Both sets are supplied in individual Tool Control EVA foam trays, providing organised storage in a professional toolbox or roll cab and making missing tools easy to identify. Individual replacement impact sockets and extension bars are also available separately, allowing workshops to maintain the complete 40-piece collection without replacing an entire set.
