Grade 5 Titanium Performance
Made from Grade 5 Titanium (Ti-6Al-4V), S-PARTS titanium fasteners combine high strength with significantly lower weight than steel hardware.
At comparable strength levels, titanium weighs only about 48% as much as steel. Under the same conditions, S-PARTS Grade 5 Titanium fasteners offer overall mechanical performance comparable to 10.9-grade steel fasteners while weighing approximately half as much as steel hardware.
S-PARTS works with a metal raw-material supply chain serving Xi'an's civilian aerospace industry and conducts long-term comparative laboratory testing to select titanium alloy material that meets its standards. The average tensile strength exceeds 1050 MPa, above the 895 MPa industry standard.
Choose a finish to match your stem or create a contrasting look. The finishes are produced using vacuum nitriding and anodizing processes.
Please Note
Candy Finish: Due to the coloring process, the Candy finish has a flowing color appearance with natural variation. The color pattern may vary from bolt to bolt.
Thread Appearance: Some bolts may show white lines around the threaded area. This is a normal result of the coloring process and does not affect normal use.
