ボルト - Bolt
WARNING: Most bolts have small markings on the head, this is standard today. We offer also a custom preparation to remove markings and re-plate the bolts to prevent corrosion. This treatment has a 50 yen markeup compare to the original price.
Two types of treatments are proposed:
- Trivalent plating treatment is a modern plating that looks similar to zinc without the chemical hazard and better consistency and corrosion resistance. This is the standard for Japanese manufacture and I recommand it for a perfect looking and lasting restoration.
- Chromate plating for resistance to corrosion. Electrogalvanizing is applied to the base, and then a chromate treatment using hexavalent chromium, which is a chemical conversion treatment, is applied. The chromate film changes its color from blue to yellow to red to red-green to green-brown to brownish brown as the chromate film immersion time of the zinc plating solution increases and the thickness of the chromate film increases. Hexavalent chromium is subject to RoHS regulations but still widely used. These are the few yellow bolts on our bikes.
