These M14x1.5 lug bolts are designed for use with wheel spacers on Audi and Volkswagen models, including the A4, S4, A5, A6, S6, S3, Jetta, Tiguan, and Passat. The set contains 20 pieces, each featuring a 40mm shank length and a ball seat profile, making them suitable for aftermarket wheel applications.

Constructed from hardened steel with a black coating, the bolts offer resistance to corrosion and daily wear. The extended shank allows proper thread engagement when using spacers, while the ball seat design ensures secure mating with compatible wheel bores. The threading follows the standard M14x1.5 pitch, matching factory specifications for many European vehicles. The bolts are machined to consistent tolerances, reducing the risk of cross-threading or installation issues. Each bolt is measured and inspected to meet quality benchmarks for aftermarket components. The black finish not only provides a uniform appearance against dark wheels but also adds a layer of protection against road salt and moisture. These bolts are intended for installation with a torque wrench to achieve recommended tightening values, promoting reliable fastening over time. In terms of functionality, the extended length bridges the gap created by wheel spacers without compromising thread depth. This design helps maintain clamping force and reduces the chance of loosening during driving. The ball seat geometry distributes load evenly across the lug nut contact area, which contributes to stable wheel attachment. The bolts are compatible with both original equipment and aftermarket alloy wheels that require a ball seat lug bolt. They are not designed for use with tapered (conical) seats or applications that demand a different thread pitch. The manufacturing process includes heat treatment to enhance tensile strength, ensuring the bolts can withstand typical driving stresses. The black coating undergoes a testing phase for adhesion and durability, though long-term performance depends on exposure conditions and maintenance practices. For optimal service life, keep the bolts clean and apply anti-seize compound sparingly to the threads during installation. These bolts are offered as a practical replacement or upgrade for vehicles fitted with aftermarket spacers, providing a secure fastening solution at a value-oriented price point. The set is packaged in a compact box for organized storage. Each bolt is identical in length and thread specification, simplifying inventory management for workshops or DIY users. While these bolts are not marketed as original equipment manufacturer parts, they are engineered to meet common aftermarket standards for fit and performance. Users should verify vehicle compatibility by checking the required thread size, seat type, and shank length before installation. The combination of extended reach, durable coating, and precision threading makes this set a versatile option for those adding spacers to their Audi or Volkswagen models.
