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

Manufactured from high-quality Chromium-Molybdenum (Cr-Mo) steel, each socket is heat treated to provide excellent strength, durability and resistance to the high loads generated by impact tools.

The sockets are suitable for use with 1/2" square drive pneumatic air tools, cordless impact wrenches and other compatible power tools.

Each socket incorporates Britool's Stress Relief Drive system, designed to increase the maximum applicable torque while helping reduce stress and damage to fasteners. The 6-point hexagon profile provides positive engagement with compatible fasteners.

A ball retaining groove on each face of the square drive provides a secure fit with 1/2" drive accessories, while the cross-drilled side holes allow optional pin-and-ring retention when additional security is required.

Each socket is laser marked with the Britool Hallmark logo and individual part number, making identification quick and easy in a busy professional workshop.

The complete set is supplied in a tool control EVA foam tray, allowing organised storage in a toolbox or roll cab drawer and making it easy to identify missing sockets.

Designed for Impact Tools

These Britool Hallmark sockets are engineered for use with compatible 1/2" drive impact and power tools.

The Cr-Mo construction and heat-treated design provide the strength required to withstand repeated impact loading and high torque applications in professional workshops.

Suitable for:

  • 1/2" pneumatic impact wrenches
  • 1/2" cordless impact wrenches
  • Workshop air tools
  • Automotive power tools
  • Heavy-duty mechanical applications
Stress Relief Drive System

Britool's Stress Relief Drive system is designed to distribute applied torque more effectively around the fastener rather than concentrating excessive stress at the corners.

Combined with the 6-point hexagon profile, this helps provide secure engagement while reducing the likelihood of rounding or damaging fasteners during high-torque work.

Tool Control Foam Storage

The complete set is supplied in a custom EVA tool control foam tray.

Approximate tray dimensions:

391mm L × 190mm D × 34mm H

The organised layout makes it easy to:

  • Identify socket sizes quickly
  • Locate tools during a repair
  • See if a socket is missing
  • Keep your toolbox organised
  • Store the set efficiently in a roll cab or toolbox drawer
Deep Profile Alternative Available

A corresponding deep-depth 1/2" drive impact socket set is also available:

LDHMPSET836

The deep version provides additional reach where standard-depth sockets do not provide sufficient access.

The Britool Hallmark Range

The Britool Hallmark range was developed by Britool in the 1980s for the automotive aftermarket and has been a long-established choice for professional workshop users.

Each socket is marked with the Britool Hallmark branding,  providing clear identification and reflecting the professional tooling heritage of the range.

The Britool Hallmark guarantee covers defects in materials and/or workmanship when tools are used for their intended purpose.

The guarantee does not cover fair wear and tear, moving parts such as ratchet mechanisms, or consumable items such as bits and repair kits.

Frequently Asked Questions

What sizes are included in the Britool Hallmark 1/2" impact socket set?
The Britool Hallmark 25-piece 1/2" drive impact socket set includes metric sizes from 8mm to 36mm, covering 8–30mm plus 32mm and 36mm. This provides excellent coverage for common automotive, mechanical, agricultural and workshop applications.
Can these Britool Hallmark sockets be used with an impact wrench?
Yes. These are impact-rated 1/2" square drive sockets, manufactured from heat-treated Chromium-Molybdenum (Cr-Mo) steel for use with compatible pneumatic air impact wrenches, cordless impact wrenches and other suitable impact tools. They should not be confused with standard chrome hand-tool sockets.
Are these Britool Hallmark impact sockets 6-point or 12-point?
These sockets feature a 6-point (hexagon) profile, which provides strong contact with the flats of compatible fasteners. The profile is particularly useful for high-torque applications as it helps provide secure engagement and can reduce the risk of rounding damaged or heavily tightened nuts and bolts.
What is the difference between the standard and deep Britool Hallmark impact socket sets?
The LHMPSET836 is the standard-depth 25-piece 1/2" drive impact socket set, while the LDHMPSET836 is the corresponding deep impact socket set. Deep impact sockets provide additional reach for recessed fasteners, longer studs and areas where a standard socket cannot provide sufficient clearance.
Are individual replacement sockets available for this Britool Hallmark impact socket set?
Yes. Individual replacement sockets are available separately, making it possible to replace a lost or damaged socket without purchasing another complete 25-piece set. This is particularly useful for professional mechanics, garages and workshops maintaining an organised 1/2" drive impact socket collection.
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.
