These are titanium bolts for fixing the visor of Shoei's X14, X15, J-Cruise, etc. This is the titanium base color, as seen in the first and second photos. The third photo and the left side of the eighth photo show the normal bolt. The fourth and fifth photos show examples of installation (dark purple titanium bolts on an X14). These are machined from extremely hard, small titanium parts, with weight-reducing cutouts. Although they are not eye-catching parts, they are subtly cool components.
