Description

Product Overview

Mardarth’s M12 wheel lug bolts are engineered to meet original equipment (OE) specifications, delivering the strength and reliability required for safe wheel attachment. Constructed from high‑grade 10.9 carbon steel, each bolt features a black oxide exterior finish that enhances corrosion resistance while maintaining a sleek, professional appearance. The hexagonal head design allows for easy torque application with standard tools, and the right‑hand thread (M12 x 1.5) ensures a secure, vibration‑resistant fit. Available in convenient packs of 5 or 20, these lug bolts are suitable for a variety of passenger cars, light trucks, and SUVs.

Usage

These lug bolts are ideal for both professional automotive service centers and home garage projects. Whether you are replacing worn bolts, performing a wheel upgrade, or conducting routine maintenance, the M12 size fits a broad range of wheel hub assemblies. The bolts are compatible with many OEM part numbers, making them a reliable replacement for factory‑installed fasteners. For optimal performance, tighten to the recommended torque of 140 Nm using a hand wrench or torque wrench, following your vehicle’s service manual. Avoid using impact tools to prevent thread damage.

FAQ

What vehicles are compatible with these M12 lug bolts?

The bolts fit any vehicle that uses an M12 x 1.5 wheel lug specification, including many models from major manufacturers. Refer to your vehicle’s parts manual or the listed compatible part numbers for exact fitment.

How do I achieve the correct torque when installing?

Use a calibrated torque wrench set to 140 Nm (approximately 103 lb‑ft). Tighten each bolt in a star pattern to ensure even pressure across the wheel hub.

Can I use an impact wrench for installation?

It is not recommended. Impact wrenches can damage the thread pitch and compromise bolt integrity. A hand wrench or torque wrench provides the precise control needed.

What is the benefit of the black oxide coating?

The black oxide (Dacromet) coating creates a hard, corrosion‑resistant surface that protects the steel from rust and wear, especially in salty or humid environments.

Do the bolts come with any warranty?

Yes, Mardarth offers a limited warranty against manufacturing defects, ensuring you receive a reliable product backed by our quality guarantee.
