LEXIVON XZN Triple Square Bit Socket Set, Extra Long 4-Inch | 10-Piece European M4–M18, S2 Alloy Steel

Meet the LEXIVON XZN Extra Long 4 Inch Triangle Socket Set LX-145L, a carefully crafted toolkit designed to ease challenging mechanical tasks on modern European vehicles. The set blends precision manufacturing with durable materials, meeting and often exceeding ANSI standards. Built for both DIY enthusiasts and professional technicians, it bridges power and control in tight spaces.

Designed for European vehicles and professional use

Designed for European vehicles including BMW, Mercedes-Benz, Volkswagen, Audi, Porsche, and more, the XZN triple-square bits fit in snugly with an active gripping finish, reducing cam-out and protecting both fasteners and tools. The long reach helps you reach stubborn fasteners without removing surrounding components, keeping the workflow smooth and efficient.

Core materials and finishes are selected to resist wear and corrosion. The XZN bits are CNC milled from S2 alloy steel to maximize hardness, while the sockets are forged in heat-treated chrome vanadium steel. A zinc phosphate finish on the bits minimizes wear between uses, and the chrome-plated sockets offer a polished mirror surface that fights rust over time.

Key benefits at a glance

• Extended Reach: The extra-long 4-inch design helps access hard-to-reach fasteners in dense engine bays.
• Secure Fit and Power: CNC-machined bits and hardened sockets deliver precise engagement and robust turning power.
• Durable Finish: Zinc phosphate on bits and chrome plating on sockets promote longevity in tough environments.
• Clear, Practical Design: Sizes are etched for quick recognition, and the case stores everything neatly for on-the-job organization.
• ANSI-Standard Quality: Built to meet or exceed standards and backed by a lifetime warranty for peace of mind.

Real-world usage scenarios illustrate the versatility of the LX-145L set. You can tackle cylinder head screws, drive components, door fittings, and other critical fasteners that demand a precise fit and extra reach. In tight engine compartments, the extra length and beveled bit ends help seat fasteners cleanly without collateral damage. The robust materials stand up to frequent use, and the finish actively resists corrosion, making this set a dependable companion for maintenance and repair tasks.

Beyond performance, the set's value lies in its thoughtful engineering. CNC precision ensures each bit aligns perfectly with fasteners, while the beveled ends aid in quick seating. The polished sockets remain resistant to rust, and the active protection on the bits keeps wear at bay across multiple sessions. While results can vary with technique and task, many users appreciate the confidence this set provides when working in challenging, limited-access spaces.
