Question 1

Which titanium grades do you use for fasteners?

Accepted Answer

Most structural bolts, nuts and racing hardware use Grade 5 titanium (Ti-6Al-4V, also called TC4), which has a minimum tensile strength of about 895 MPa. We use Grade 2 commercially pure titanium for parts where formability and corrosion resistance matter more than strength. Timascus (Mokuti) layered titanium is used for decorative EDC parts.

Question 2

Can a Grade 5 titanium bolt directly replace a steel bolt?

Accepted Answer

Grade 5 titanium is roughly comparable in strength to property class 8.8 steel and about 44% lighter. It is not a like-for-like substitute for class 10.9 or 12.9 steel bolts in critical joints such as brake rotors, engine internals or suspension pivots. In those cases, increase the bolt size or have the joint checked by an engineer.

Question 3

How do you prevent galling on titanium threads?

Accepted Answer

Titanium threads can gall under load. Apply a titanium-compatible anti-seize compound, tighten to torque values adjusted for the lubricant, and avoid power tools for final tightening. Rolled threads and controlled surface finish also reduce galling risk.

Question 4

How are anodized titanium colors produced?

Accepted Answer

Titanium anodizing grows a thin oxide layer whose thickness, controlled by voltage, produces colors such as bronze, purple, blue, gold, green and rainbow by light interference. It uses no dye and adds no measurable weight. For better wear resistance on high-contact parts, PVD coating is an option.

Question 5

Which fastener standards and custom drawings can you work with?

Accepted Answer

We manufacture to DIN, ISO metric, ANSI/inch and JIS standards. We also produce custom parts from customer drawings in PDF, STEP or IGES format, and send CNC process photos and videos during production.

Question 6

What is the typical minimum order quantity?

Accepted Answer

Typical MOQs range from 50 to 300 pieces per specification, depending on part complexity and finish. Some Timascus items are available from 1 piece. Contact info@bicyclebolt.com with your specification for confirmation.
