Thunder Bolt's the bolts, nuts, and washers are made from aerospace grade Gr.5 6AL-4V titanium alloy (American name ASTM B348), hot forged, and then threaded with high precision CNC machining. Titanium, which is said to be the most demanded material in the world today, is actively used in the latest passenger planes, and is a rare metal that is attracting the most attention as a light, strong, and rust-free metal. In addition, PVD treatment (Physical Vapor Deposition Nitride Coating), which is excellent in abrasion resistance, is applied to protect your precious bike from corrosion by contact with different kinds of metal (galling) as well as fashionable coloring.
