Description
Titanium flange bolts with 6 points are designed for applications
requiring high strength, corrosion resistance, and lightweight performance.
These bolts are stronger than stainless steel, yet significantly lighter, making them ideal for high-performance
and weight-sensitive industries such as aerospace, automotive, and medical.
Titanium 6-point flange bolts are non-magnetic, non-toxic, and biocompatible, which also makes them suitable for electronic, electrical, and medical device applications.
In addition to excellent corrosion resistance and heat resistance,
titanium flange bolts maintain superior fatigue resistance, ensuring durability under high stress and temperature
environments.
Applications
Titanium flange bolts with 6 points are widely used in:
Automotive industry – for high-stress components such as valve covers, exhaust
manifolds, connecting rods, brake callipers, wheel hubs, and
suspension systems
Aerospace and aviation – structural fastening and high-temperature assemblies
Marine industry – anti-corrosion fasteners for ship components
Electronics and electrical – due to non-magnetic and non-conductive properties
Medical devices – used in biocompatible assemblies and surgical equipment
General engineering and construction – in areas requiring strength with reduced weight
