Britool Hallmark 25pc 1/2 Drive Impact Socket Set 8-36mm 12 Point Cr-Mo

The Britool Hallmark 25-Piece 1/2" Drive Impact Socket Set is a comprehensive professional metric socket set covering sizes from 8mm through to 36mm, with 25 individual sockets supplied in dedicated EVA tool control foam.

Manufactured from high-quality Chromium-Molybdenum (Cr-Mo) steel, these sockets are specifically designed for use with compatible pneumatic air impact tools and powered impact wrenches, providing the strength and durability required for demanding automotive, mechanical and workshop applications.

Each socket features a 12-point / bi-hexagon profile, providing multiple engagement positions for easier alignment with compatible fasteners, particularly where access or tool positioning is restricted.

For secure socket retention, each socket incorporates a cross-drilled hole, allowing the use of an appropriate pin and retaining ring when required. This is particularly useful in professional impact-tool applications where secure socket attachment is important.

The set covers an extensive selection of metric sizes from 8mm to 36mm, making it suitable for professional garages, automotive technicians, commercial vehicle workshops, engineers, maintenance departments and other demanding trade environments.

Chromium-Molybdenum Cr-Mo Construction

These Britool Hallmark impact sockets are manufactured from high-quality Chromium-Molybdenum steel, commonly referred to as Cr-Mo steel.

Cr-Mo steel is used for professional impact sockets where the tools are required to withstand the repeated forces generated by compatible powered and pneumatic impact equipment.

Unlike conventional chrome hand sockets, these sockets are specifically designed for impact-tool applications.

Always use appropriately rated impact sockets and accessories when operating an impact wrench or compatible powered impact tool.

12-Point / Bi-Hexagon Profile

Each socket incorporates a 12-point bi-hexagon profile for engagement with compatible fasteners.

The 12-point configuration provides multiple engagement positions around the fastener, making alignment easier, particularly where surrounding components restrict positioning of the impact tool.

The correct socket size should always be selected and the socket should be fully engaged with the fastener before the impact tool is operated.

Cross-Drilled Retention Holes

Each socket incorporates a cross-drilled retention hole.

This allows an appropriate retaining pin and ring system to be used where required, helping securely retain the socket on a compatible impact tool or accessory.

This feature is particularly useful in professional workshop environments where sockets may be subjected to frequent and repeated impact operation.

Professional Automotive & Workshop Applications

The combination of 1/2" drive, Cr-Mo construction, 12-point profiles and a comprehensive 8-36mm metric size range makes this set suitable for applications including:

• Professional automotive servicing
• Vehicle repairs and maintenance
• Engine and drivetrain work
• Suspension and chassis repairs
• Commercial vehicle servicing
• Fleet maintenance
• Mechanical engineering
• Machinery maintenance
• Industrial servicing
• Professional garages
• Engineering workshops
• General impact-tool applications

Individual Socket Identification

Every socket is laser marked with the Britool Hallmark logo and its individual part number, making identification straightforward within a busy professional workshop.

The individual markings help users quickly identify the required size and make it easier to locate the correct replacement socket when necessary.

Individual sockets from this range are available separately as and when required, allowing missing or worn sizes to be replaced without purchasing another complete set.

EVA Tool Control Foam

The complete 25-piece set is supplied in precision-cut EVA tool control foam, providing organised and professional storage for every socket.

Each socket has its own designated position, allowing the required size to be quickly identified while also making it easy to see when a socket has not been returned after completing a job.

The foam tray is designed for convenient installation into a compatible professional toolbox or roll-cab drawer.

Foam Tray Dimensions

The approximate EVA foam tray dimensions are:

• Length: 391mm
• Depth: 190mm
• Height: 34mm

We recommend checking the available internal dimensions of your toolbox or roll-cab drawer if the tray dimensions are critical.

The Britool Hallmark Range
