Description
Product Overview
Our M14 x 1.5 lug bolts are crafted from high‑grade Class 10.9 carbon steel and finished with a premium multi‑layer chrome coating. The hex head measures 17 mm, while the thread length is 28 mm, providing ample engagement for a solid clamping force. Each bolt features a ball seat design that matches factory specifications, ensuring a perfect fit for aftermarket wheels that require a smaller nut cavity. The kit includes 20 pieces, each tested to meet or exceed SAE standards, delivering consistent torque and resistance to shear forces up to 577 MPa.
Usage
These bolts are ideal for installing aftermarket alloy wheels on vehicles equipped with M14 x 1.5 threads, such as Mercedes‑Benz C300, C43 AMG, CLA250, EQB 300, and many other models from 2008 onward. They perform exceptionally in daily driving, spirited performance, and even light off‑road conditions, thanks to their corrosion‑resistant chrome finish and high tensile strength. Whether you are a professional installer or a DIY enthusiast, these bolts provide the confidence needed for secure wheel mounting.

FAQ
Are these bolts compatible with my OEM wheels?
These bolts are intended for aftermarket wheels that use M14 x 1.5 threads. While they may fit some OEM wheels, the lug seat size can differ, potentially reducing clamping force. Verify the seat dimensions before installation.
What is the difference between the chrome and black finishes?
Both finishes use the same high‑grade steel and thread specifications. The chrome finish offers a classic, reflective look and excellent corrosion resistance, while the black finish provides a stealthy aesthetic with comparable durability.
Can I use these bolts on vehicles other than Mercedes‑Benz?
Yes, any vehicle that specifies M14 x 1.5 lug bolt threads can use these bolts, provided the wheel’s lug seat matches the ball seat design. Always confirm fitment with the wheel manufacturer.
How do I ensure proper torque when installing?
Follow the vehicle’s service manual for the recommended torque value, typically between 80‑100 Nm for M14 x 1.5 bolts. Use a calibrated torque wrench to achieve consistent clamping force.
What warranty does this product carry?
We offer a limited one‑year warranty against material defects and finish failure. The warranty does not cover damage caused by improper installation or misuse.
