Wheel Lug Bolt Overview

Febi wheel lug bolt 49009 is a direct-fit hardware solution for Mercedes-Benz applications that use a spherical collar and M12 x 1.5 thread. It is built for light alloy rims and uses a zinc-lamella coated finish for added surface protection.

Key Features

• Spherical collar for proper wheel fastening element contact
• M12 x 1.5 outside thread with 20 mm thread length
• Hexagonal fastening type with 17 mm wrench size
• 10.9 tensile strength grade for demanding wheel hardware use
• Zinc-lamella coated surface for corrosion resistance
• Designed for light alloy rims

Detailed Description

Febi 49009 is a wheel lug bolt specified for Mercedes-Benz models that require a spherical-seat fastening design. The bolt dimensions, thread pitch, and collar shape are important for correct wheel seating and secure fastening on compatible Mercedes-Benz SLK, CLK, E-Class, and SL applications. If you are replacing worn or damaged wheel hardware, this part number 49009 provides the dimensional and material specifications needed for the application.

Febi 49009 is a practical choice when the original wheel bolt shows corrosion, damaged threads, rounded hex edges, or improper seating at the wheel face. The zinc-lamella coated finish and 10.9 strength rating support use in wheel fastening applications where consistent clamping and fitment matter. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Solve

• Worn or corroded wheel bolts
• Damaged threads that prevent proper tightening
• Improper wheel seating from the wrong collar shape
• Rounded bolt heads that make removal difficult
• Replacement needs for light alloy rim wheel fastening

Installation Notes and Tips

Verify the wheel seat style, thread size, and bolt length before installation. Use the correct 17 mm wrench size and confirm that the bolt seats fully against the wheel surface without binding. For Mercedes-Benz fitment, match the spherical collar specification exactly to the vehicle and wheel combination.
