Titanium Fastener FAQ
Answers drawn from a decade of supplying motorcycle, bicycle and automotive aftermarket brands. Need data for a specific application? Our engineers reply within 7 hours on average.
Ask an EngineerWhat is the difference between GR5 and GR2 titanium bolts?
GR5 (Ti-6Al-4V) is an alpha-beta alloy with a minimum tensile strength of about 895 MPa and a density of 4.43 g/cm³ — the standard for load-bearing bolts such as brake disc, axle and caliper fasteners. GR2 is commercially pure titanium (about 345 MPa minimum tensile strength) and is better suited to low-load, high-corrosion uses like covers and decorative screws. All Zunvo structural fasteners are made from GR5 unless you specify otherwise.
Can GR5 titanium bolts replace steel bolts on a motorcycle?
For most positions, yes. GR5 titanium is broadly comparable in tensile strength to property class 8.8 steel while being roughly 44% lighter at identical dimensions. Where the vehicle manufacturer specifies class 10.9 or 12.9 steel, we review the joint and may recommend upsizing the thread or keeping steel — we would rather lose an order than supply an unsafe part.
How are the colors on anodized titanium screws produced?
Titanium colors — gold, bronze, purple, blue and rainbow — come from light interference in a thin surface oxide layer whose thickness is set by the anodizing voltage. No dye is used, so colors do not fade in sunlight, though they can wear where tools or friction abrade the surface. For high-wear areas we recommend PVD coating, which is harder and more scratch resistant.
What is the MOQ and lead time for custom titanium fasteners?
MOQ usually starts at 100–200 pieces or dozens depending on the part. Samples for standard geometries are typically ready in about 3 days, stock items ship within 24 hours, and custom batches generally ship 7–15 days after sample approval.
How do I prevent galling when installing titanium bolts?
Apply a titanium-compatible anti-seize compound to the threads and under the head, tighten to the vehicle manufacturer's torque specification with a calibrated torque wrench, and avoid high-speed impact drivers. Anti-seize also limits galvanic corrosion where titanium meets aluminum brackets or wheel hubs.
Which payment and shipping methods are supported?
We accept T/T and PayPal in USD. Orders ship by DHL, FedEx or UPS express, by air freight, or by sea with door-to-door service to North America, Central America, the Middle East and Southeast Asia.
