Precision-machined construction

Precision-machined construction

Each MG-line Hexagonal Nut is precisely machined to achieve clean geometry, sharp edges and a high-quality fit. The substantial hexagonal form creates a solid technical appearance that works particularly well with classic BBS and period-inspired wheel designs.

Raw CNC machine finish

Raw CNC machine finish

The CNC Machine Finish leaves the machined surface visible, highlighting the geometry and manufacturing character of the component. The result is a clean, technical appearance with a raw aluminum-style look that works especially well on motorsport, OEM+ and classic builds.

Fitment designed around the original wheel center

Fitment designed around the original wheel center

Each Hexagonal Nut configuration is designed around the mounting system of the compatible wheel. Depending on the application, the nut uses the original threaded wheel center or a dedicated MG-line mounting adapter prepared specifically for the wheel geometry.

Why choose the CNC Hexagonal Nut for BBS RC 090?

The center hardware is a defining part of the BBS RC 090 / BMW Style 5 design. The hexagonal nut reinforces its classic motorsport character while the raw CNC finish introduces a more purposeful mechanical detail.

MG Hexagonal Nuts – Frequently Asked Questions
How is the Hexagonal Nut mounted on BBS RC 090 / BMW Style 5 wheels?

This version uses a dedicated mounting adapter developed for the BBS RC 090 wheel center. The adapter positions the Hexagonal Nut correctly and is supplied as part of the product configuration.

Are all MG Hexagonal Nuts mounted in the same way?

No. The mounting system depends on the wheel application. Selected BBS models use direct 58 mm or 71 mm thread configurations, Lenso BSX uses its compatible internal wheel-center thread, while other applications use a dedicated MG-line mounting adapter.

Which products use the 58 mm or 71 mm thread options?

Compatible BBS RC 300 Series, BBS RS / RSII / RC and BBS RC 041 / BMW Style 29 applications are available with 58 mm and 71 mm thread configurations. The correct option must correspond with the original threaded wheel center.

Which products use a dedicated mounting adapter?

BBS RC 090 / BMW Style 5, BBS Styling 101 and BBS RT075 configurations use dedicated mounting adapters. The Mirror Polished BBS RF Series version also uses an adapter-based mounting solution.

What is the difference between CNC Machine Finish and Mirror Polished?

CNC Machine Finish retains the visible machined surface for a more technical and raw appearance. Mirror Polished versions are further finished to achieve a smooth, highly reflective surface with a more classic and premium character.

Do these nuts replace the way the wheel is attached to the vehicle?

No. MG-line Hexagonal Nuts are wheel-center components and do not replace the original wheel-to-hub mounting system.

Are these original BBS or Lenso products?

No. They are aftermarket products manufactured by MG-line and designed for compatible wheel applications. Wheel manufacturer and model names are used to identify compatibility.
