Professional Spline / XZN Bit Socket Set

The Britool Hallmark 8-Piece Spline / XZN Bit Socket Set provides a versatile selection of specialist 12-point male XZN bits covering sizes from M5 through to M16.

Also commonly known as Spline or Triple Square bits, XZN fasteners are frequently encountered in automotive servicing, particularly on European vehicles where high-strength fasteners are used on drivetrain, suspension, braking and engine components.

The set combines 3/8" drive sockets for M5–M12 with larger 1/2" drive M14 and M16 sockets, providing an appropriate drive platform across the size range.

Comprehensive M5–M16 Size Range

The set contains eight XZN / Spline bit sockets across two drive sizes:

3/8" Drive XZN Sockets

M5, M6, M8, M9, M10 and M12

These sizes provide excellent coverage for many commonly encountered automotive XZN fasteners.

1/2" Drive XZN Sockets

M14 and M16

The larger M14 and M16 bits are fitted into 1/2" drive sockets, providing compatibility with larger hand tools when working with higher-torque fasteners.

12-Point XZN / Triple Square Profile

Each socket incorporates a precision 12-point male XZN profile, designed specifically for corresponding internal XZN fasteners.

XZN is also widely referred to as:

• Spline
• Triple Square
• 12-Point Spline
• XZN Spline

The multiple-point profile provides excellent contact between the tool and fastener, making XZN fasteners particularly suitable for automotive applications where effective torque transfer is required.

High-Quality S2 Steel Bits

The fixed XZN driver bits are manufactured from high-quality S2 tool steel, selected for its excellent combination of hardness, strength and resistance to wear.

Maintaining an accurate profile is particularly important when working with multi-point fasteners. A correctly fitting, high-quality bit helps provide effective contact with the fastener while reducing the likelihood of slipping or damaging the fastener profile.

Chrome Vanadium Steel Sockets

The socket bodies are manufactured from durable Chrome Vanadium steel and feature an attractive polished mirror finish.

This combination provides the strength and durability required for regular professional workshop use while the polished surface makes the sockets easier to clean and helps provide resistance against corrosion.

3/8" & 1/2" Square Drive Compatibility

Using two different drive sizes makes this set particularly practical for professional automotive work.

The M5–M12 sockets use a 3/8" square drive, making them compatible with suitable:

• 3/8" drive ratchets
• Extension bars
• Breaker bars
• Flexible handles
• Sliding T-handles

The larger M14 and M16 sockets use a 1/2" square drive, allowing them to be paired with suitable larger ratchets and breaker bars where increased leverage may be required.

Automotive XZN / Spline Applications

XZN / Triple Square fasteners are particularly common in the automotive industry and are frequently encountered on European vehicles.

Depending on the manufacturer, model and production year, applications can include:

• Driveshaft and CV joint fasteners
• Hub and axle assemblies
• Brake components
• Suspension components
• Gearboxes and transmissions
• Clutch and flywheel assemblies
• Cylinder head fasteners
• Engine components
• Seat mounting bolts
• Drivetrain components
• Other high-torque automotive assemblies

Always check the fastener profile and required size before applying torque.

Particularly Useful for European Vehicle Servicing

XZN fasteners are widely associated with European vehicle manufacturers and are especially common across many Volkswagen Group (VAG) applications, including Volkswagen, Audi, SEAT and Škoda vehicles.

They may also be encountered on vehicles and components from other European manufacturers.

For professional mechanics servicing European vehicles, a comprehensive selection of XZN sockets is therefore a valuable addition to the workshop tool kit.

EVA Tool Control Foam Storage

The complete set is supplied in a precision-cut EVA tool control foam tray, helping keep all eight sockets organised and easy to identify.

Each tool has its own dedicated storage position, making it quicker to select the required size and easier to identify when a socket has not been returned after use.

The tray is designed for convenient storage inside suitable:

• Toolboxes
• Top box drawers
• Roll cab drawers
• Workshop tool storage systems

Compatibility

This set is designed specifically for fasteners with a compatible internal XZN / Triple Square profile.

Although XZN fasteners can look similar to some other multi-point designs, XZN, Ribe and Torx are different fastener profiles and should not be treated as interchangeable.

Always identify the fastener correctly and select the appropriate size before applying torque.

Please note: These are hand-tool bit sockets. They should not be used with pneumatic or cordless impact wrenches unless specifically stated as impact rated.
