These Pro-Bolt Flanged Hex Head Race Spec Titanium Bolts are made from aircraft grade Ti-6AL-4V titanium (Grade 5), the outstanding benefits are rolled threads that feature greater fatigue strength and reduced galling (where friction can cause two titanium components to bond together). These bolts have in excess of 120,000Psi ultimate tensile strength, suitable to replace both Grade 5 and Grade 8 steel bolts or any bolt in a stressed area.These Race Spec bolts are designed for racing applications. By reducing the socket size, head diameter and scooping out the head - a massive 45% weight reduction is achieved compared to standard steel bolts - all with no compromise to the strength of the bolt! The advantage of high strength along with weight saving is widely recognised by top race teams around the world. The range of bolts are supplied 'off the machine' with no polishing. Material Specification: Ti-6AL-4V Ti-6AL-4V, an alloy introduced in 1954, is a good general purpose grade. Its den
