RAU Titanium M7 assembly hardware is the quintessential upgrade for your 2-Piece and 3-Piece alloy wheels and making them stand out from the rest. Replacing your assembly hardware can save you nearly 1.0Lb per wheel, and is highly corrosion resistant. This means no more chipping, peeling, fading and rusting assembly hardware. These bolts will outlast the wheels they are installed onto. The M7 bolt size is typically found on Japanese multi-piece alloy wheels.
