The nuts are designed one size smaller for a lighter and more compact look.
Titanium bolts form a non-conductive coating on their surface, making them virtually rust-proof.
The M8 size is mainly compatible with off-road bikes from the four major Japanese manufacturers, and some on-road bikes (for axle block type vehicles with bolt adjustment).
The M10 size is mainly compatible with KTM off-road models, Husqvarna, and others.
