Repute Steel & Engineering Company supplies a comprehensive range of titanium fasteners, including Ti-6Al-4V bolts, titanium nuts, screws, and aircraft fasteners. Titanium fasteners are well-regarded for their excellent strength-to-weight ratio, corrosion resistance, and ability to withstand high temperatures. These products are available in various grades to meet diverse application needs. Grades 1 through 4 are commercially pure titanium, known for their superior corrosion resistance and formability. Meanwhile, alloyed grades, such as Grade 5 (6Al-4V), offer enhanced mechanical properties due to the addition of elements like aluminum, vanadium, molybdenum, manganese, and iron.
The Grade 5 Titanium Hex Head Bolt, also known as 6Al-4V, is a widely used aerospace-grade fastener with approximately 6% aluminum and 4% vanadium content. This grade delivers medium strength, high corrosion resistance, and the capability to perform under moderately high temperatures without creeping. Additionally, Titanium Grade 2 Fasteners, a commercially pure grade, are preferred for applications requiring excellent corrosion resistance and good heat resistance. Both grades are suitable for aerospace, marine, automotive, and industrial applications.
Repute Steel & Engineering Company stands as one of the oldest and most trusted manufacturers of Aerospace Titanium Fasteners, offering high-quality products like Titanium Socket Head Cap Screws, Titanium Threaded Stud Bolts, and Titanium 12-Point Bolts. Each fastener is manufactured with precision to ensure optimal performance in critical applications.
