Product Summary

The Britool Hallmark 3/8" Drive Impact Socket Set is a professional-quality solution for mechanics, technicians and engineers requiring reliable performance in demanding environments. Manufactured from premium Chromium-Molybdenum (Cr-Mo) steel, these impact-rated sockets are engineered to withstand the high torque generated by pneumatic and cordless impact tools.

The set includes both standard and deep sockets in metric sizes from 7mm to 22mm, making it suitable for a wide variety of automotive, commercial vehicle and industrial maintenance tasks. Supplied in a durable EVA foam tool control tray, every socket has its own dedicated location, helping to keep tools organised, protected and readily accessible in any workshop or service vehicle.

Construction & Materials

Each socket is precision manufactured from high-quality Chromium-Molybdenum (Cr-Mo) steel, the industry standard material for professional impact socketry. Cr-Mo steel offers exceptional toughness, impact resistance and long service life, making it ideal for repeated high-torque applications where conventional chrome sockets are unsuitable.

The sockets feature a durable industrial finish that helps resist corrosion, workshop contaminants and everyday wear while maintaining a professional appearance. Every socket is permanently laser marked with the Britool Hallmark branding and size for quick identification, even after prolonged workshop use.

Features & Benefits

This versatile set contains a combination of standard and deep impact sockets, allowing easy access to both standard fasteners and recessed nuts or bolts.

Included metric socket sizes are:

7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm and 22mm.

Designed for use with 3/8" square drive impact wrenches, each socket incorporates a retaining pin and ring hole for secure attachment during high-torque applications where additional socket retention is required.

The six-point socket profile provides maximum contact with fasteners, helping to reduce the risk of rounding bolt heads while transferring torque more efficiently. Whether carrying out routine servicing or heavy-duty repairs, this set delivers dependable performance for professional users.

• Automotive servicing and repairs
• Commercial vehicle maintenance
• Agricultural machinery

Its comprehensive metric size range makes it an excellent all-round socket set for both everyday maintenance and more demanding repair work.

Storage & Organisation

The complete socket set is supplied in a precision-cut EVA foam tool control tray, ensuring every socket has its own clearly defined position. This not only speeds up tool selection but also makes it easy to identify missing sockets at a glance.

The tray is designed to fit neatly into most professional toolboxes, roller cabinets and workshop drawers, helping to keep your workspace organised while protecting the sockets during storage and transport.
