Aeroflow Performance Titanium 12 Point Head bolts, studs and nuts are machined from 6AL-4V grade 5 Titanium and the small head design is ideal when fitting into a recess or tight areas to give maximum clearance. These titanium bolts are the favored material for a fastener due to the attractive property of being a low-density metal, which has a higher tensile strength than many other materials, even in higher temperatures. Given this strength, titanium is remarkably light. When compared to steel in a strength-to-weight ratio, titanium is far superior, as it is as strong as steel but 45% lighter. In fact, titanium has the highest strength-to-weight ratio of all known metals. The pairing of their high strength to weight ratio, excellent resistance to stress corrosion cracking, high corrosion resistance and good fatigue strength make it the best choice to have in your race car. Each bolt is sold individually and available in a variety of threads and lengths to choose from.
