Britool Hallmark 19pc 3/8" 12 Point Socket Set 6-24mm Chrome Vanadium

The Britool Hallmark 19-Piece 3/8" Drive 12-Point Socket Set is a professional-quality hand socket set designed for automotive servicing, mechanical repairs, engineering and general workshop applications.

Manufactured from high-quality Chrome Vanadium steel, the sockets provide the strength, durability and reliable performance required for regular professional hand-tool use.

Each standard-depth socket features a 12-point bi-hexagon profile, providing additional engagement positions compared with a conventional 6-point socket. This can be particularly useful when working with a hand ratchet in confined areas where the available swing or repositioning space is limited.

The comprehensive metric range covers 6mm through to 24mm, giving professional mechanics and technicians excellent coverage of commonly encountered fastener sizes.

Each socket is individually stamped with the Britool Hallmark branding and part number, making identification straightforward and allowing individual sockets to be replaced separately if lost or damaged.

The complete set is supplied in a branded red and black EVA tool control foam tray, providing organised storage that fits neatly into a professional toolbox, top box or roll cab drawer.

Socket Dimensions

Socket lengths vary according to size:

• 6mm socket: approximately 28mm overall length
• 24mm socket: approximately 31mm overall length

The compact standard-depth profile makes the set particularly suitable for everyday workshop applications where a deep socket is not required.

12-Point Bi-Hexagon Profile

The 12-point socket profile provides twice as many engagement positions around a compatible hexagonal fastener as a 6-point profile.

This can make positioning the socket easier when working in restricted areas, particularly when using a ratchet where only a limited amount of movement is available.

The bi-hexagon design makes this set a versatile choice for professional mechanics and engineers carrying out general automotive and mechanical fastening work.

Automotive & Professional Workshop Applications

The wide 6-24mm metric size range makes this Britool Hallmark socket set suitable for numerous applications, including:

• Car servicing and vehicle maintenance
• Engine and under-bonnet repairs
• Automotive workshops and garages
• Mechanical engineering
• Machinery maintenance
• General workshop repairs
• Assembly and maintenance work
• Professional mechanic and technician use
• Home garage and enthusiast applications

These are Chrome Vanadium hand sockets and are intended for use with compatible 3/8" drive hand ratchets, extension bars, breaker handles and other appropriate hand-tool accessories.

Tool Control EVA Foam Storage

The complete set is supplied in a branded red and black EVA tool control foam tray.

Approximate foam dimensions:

198mm W × 191mm H × 36mm D

The compact tray is designed to fit neatly into a toolbox, top box or roll cab drawer, helping maintain an organised professional workspace.

The individual tool positions make it easy to locate the required socket quickly and immediately identify if a socket is missing after completing a job.

Individual Replacement Sockets

Individual socket sizes from this set are available separately as and when required.

This allows professional workshops and mechanics to replace a lost or damaged socket without purchasing another complete set, helping maintain a complete 6-24mm Britool Hallmark socket collection.
