The Britool Hallmark 25-Piece 1/2" Drive Deep Impact Socket Set is a professional-grade socket collection designed for demanding automotive, mechanical and workshop applications.

Manufactured from premium Chromium-Molybdenum (Cr-Mo) steel and heat treated for durability, these deep impact sockets are engineered to withstand the high torque and shock loads generated by suitable pneumatic and cordless power tools.

The 6-point hexagon profile provides secure engagement with fasteners, helping reduce the risk of rounding and fastener damage. Britool's Stress Relief Drive system allows higher torque to be applied while helping distribute loading away from the corners of the fastener.

Each socket features a ball retaining groove on every face of the square drive, providing a secure connection with compatible 1/2" drive accessories. Side holes are also provided for optional pin-and-ring retention when additional security is required during heavy-duty impact applications.

The complete set is supplied in a tool control EVA foam tray, keeping all 25 sockets organised and easy to identify inside a toolbox, top box or roll cab drawer.

Why Choose Deep Impact Sockets?

Deep impact sockets provide additional length compared with standard sockets, making them particularly useful for fasteners positioned on long studs or recessed components.

Combined with the robust Cr-Mo construction and 6-point profile, this set is designed to provide dependable performance under demanding workshop conditions.

The wide 8mm–36mm metric range gives professional users excellent coverage for many common automotive, mechanical and industrial applications.

Frequently Asked Questions

What are deep impact sockets used for?
Deep impact sockets provide additional reach compared with standard-depth sockets, making them particularly useful for fasteners located on long studs, recessed components or difficult-to-access areas. The Britool Hallmark 25-piece 1/2" drive deep impact socket set is ideal for automotive, mechanical, industrial and heavy-duty workshop applications.
Are the Britool Hallmark deep sockets suitable for impact wrenches?
Yes. These 1/2" drive deep impact sockets are manufactured from heat-treated Chromium-Molybdenum (Cr-Mo) steel and are designed to withstand the high torque and shock loads generated by suitable pneumatic and cordless impact tools. They should be used with appropriate impact-rated equipment and accessories.
What sizes are included in the Britool Hallmark 25-piece deep impact socket set?
The set provides 25 metric 6-point deep impact sockets covering sizes from 8mm to 36mm:

8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 32 and 36mm.

This broad size range provides excellent coverage for many common automotive, mechanical and industrial fasteners.
Why do these Britool impact sockets have a 6-point hexagon profile?
The 6-point hexagon profile provides strong contact with the flats of the nut or bolt, helping distribute torque more effectively and reducing the risk of fastener rounding or damage. The Britool Stress Relief Drive system is also designed to help distribute loading away from the corners of the fastener during high-torque applications.
How are the sockets retained on a 1/2" drive impact tool?
Each socket features a ball retaining groove on every face of the 1/2" square drive, helping provide secure retention with compatible impact accessories. The sockets also have side holes for optional pin-and-ring retention, providing additional security where required during demanding impact applications.
When should I use a deep impact socket instead of a standard impact socket?
A deep impact socket is the better choice when a fastener is positioned on a long exposed stud, recessed inside a component or beyond the reach of a standard socket. The additional socket depth allows the fastener to sit further inside the socket while still providing secure engagement. For professional automotive and mechanical work, having both standard and deep 1/2" drive impact sockets provides greater flexibility for different fastening applications.
