SPM (Super Precision Machine Cut) titanium screw series M4 x 8mm set screw. Reve D has produced an M4 x 8mm set screw using high-precision cutting with our lightweight / high-rigidity titanium material.
The tip has a smooth design with no edges, so it is ideal for down stop/droop screws commonly used in racing. Replacing with a lightweight titanium screw is effective in reducing the weight of the suspension arms.
