LEXIVON LX-145S Triple Square Bit Socket Set, 8-Piece S2 Steel, Dual Drive

The super-short profile of the LEXIVON LX-145S helps you reach XZN fasteners in tight automotive spaces, while its dual-drive selection covers jobs that call for different socket drives. With eight sizes from M4 to M16, this set brings commonly used triple-square bits together on one organized rail.

CNC-machined from S2 alloy steel, the bits have chamfered edges for a smooth fit on fasteners. The black phosphate finish helps protect against rust and corrosion, and laser-etched size markings make it easier to pick the right bit at the bench or beside the vehicle.

Product specs

• Type: XZN (triple square) bit socket set
• Set size: 8 pieces, M4 to M16

The range of sizes makes this a practical choice when a repair calls for several XZN fasteners, rather than a single-size bit. The laser markings on each bit and the drive-size information on the rail help keep identification straightforward as you move between fasteners.

Compatibility & requirements

Designed for automotive work with XZN/triple-square fasteners, these bits suit use with manual torque tools. The fastener type is commonly found in areas such as cylinder head bolts, drivetrain components and caliper fasteners. The listed vehicle applications include BMW, Mercedes-Benz, Volkswagen, Audi and Porsche, select the bit to match the fastener size and drive required for the job.

For a repair in a confined area, the super-short format can make access more manageable. If your work is instead centred on general-purpose fastening, a standard bit set may cover a broader mix of fastener styles, this set focuses on the XZN sizes used in automotive applications.

Who it’s for

This set is suited to DIYers and professionals maintaining vehicles that use triple-square fasteners. It brings the listed M4–M16 sizes together in one place, so it can be useful for jobs involving different fastener sizes across a vehicle. The rail keeps the bits arranged and accessible between tasks, while the etched markings help distinguish them without sorting through loose pieces.

Customers commonly highlight the set’s fit, construction and storage, and describe it as useful for work on Audi, Volkswagen and other European vehicles. Those comments reflect buyer feedback, the appropriate bit still depends on the fastener being serviced.

What to clarify

Which sizes are in the set? It contains M4, M5, M6 and M8 bits with a 1/4-inch drive, plus M10, M12, M14 and M16 bits with a 3/8-inch drive.

What does XZN or triple square mean here? It refers to the fastener style these bits are made to engage. XZN fasteners are commonly used in automotive locations including cylinder head bolts, drivetrain components and caliper fasteners.

How are the bits kept organized? They sit on an aluminium storage rail with a secure socket mechanism. The sizes are laser-etched on the bits, and the rail displays the square drive size for quick identification.

Is it worth it?

If your automotive work regularly involves XZN fasteners, the LX-145S combines a focused spread of eight sizes with two drive sizes, a compact profile and an organized rail. That makes it a useful set to keep ready for repairs where matching the right triple-square bit and reaching the fastener efficiently matter.
