Titanium SEMS screws are used a lot on bicycles. A titanium washer made together behind the thread and will not be took off.
This combination avoids loosing the washer after uninstalling the titanium bolt/screw.
- M5 rolled threads – smoother, stronger and more durable than CNC cut threads.
- Made from Gr5 (ti6al4v) solid titanium bar, fully inspected by supersonic detection.
- Available also in GR1, GR2, GR9 etc. titanium grades.
- Customizable threads (metric or inch) and lengths.
- Anodizing & PVD coatings optional.
- Available materials are: aluminum, stainless, copper, copper alloy, brass, zirconium, molybdenum, tungsten etc.
Materials of Titanium Bolts with Washers
The following grades of materials are optional as regular stocked materials. If required material grade is not listed, please let us known.
In this table, the composition and strength of the materials are listed.

Compared to other commonly used metals, Titanium Bolts with Washers are easy to make, light and corrosion resistant, yet it does not require surface treatment in most circumstances.
The following table also shows the comparison of titanium alloy, stainless steel and aluminum alloy that are used for machinery parts and industrial fasteners like bolts/screws, nuts and washers etc.
| Material | Property | Density | Tensile | Yield | Typical Application |
| Typical Grade | gram/cm3 | Mpa | Mpa | ||
| Titanium Alloy | Gr5 (Ti6Al4V) | 4.43 | 895 | 828 | Aviation |
| 304 Stainless Steel | 304(08Cr19Ni9) | 7.93 | 515 | 205 | Kitchen Utensils |
| Aluminum Alloy | 7075 | 2.81 | 560 | 495 | Aviation |
