Overview
Titanium fasteners are bought for one of three reasons: seawater, weight, or chemical resistance. The grade follows from the reason. Grade 2 where the environment is the problem and the load is modest; Grade 5 where the joint has to carry real load without a weight penalty; Grade 23 where the application is precision or regulated.
The orders tend to be small and mixed — a maintenance kit, a refit, a set of fastener sizes for a machine build. That is the kind of work a one-stop titanium supplier handles well and a mill often will not.
Product range
| Product | Grades | Notes |
|---|---|---|
| Hex bolts | Gr2, Gr5 | Part-threaded and fully threaded |
| Socket head cap screws | Gr2, Gr5 | Internal hex drive |
| Threaded rod / studding | Gr2, Gr5 | Cut to length; the form most often ordered for marine refits |
| Studs (double-ended) | Gr2, Gr5 | Threaded both ends, per drawing or standard |
| U-bolts | Gr2, Gr5 | With nuts, bent to size |
| Hex nuts | Gr2, Gr5 | Matched to the bolt grade |
| Washers | Gr2, Gr5 | Flat and plain |
Sizes, thread forms and finishes are confirmed per enquiry. Where a figure depends on the specific order it is confirmed in the quotation — please contact us for confirmation.
Standards referenced
Fasteners can be produced to dimensional and material standards that match your existing system:
- DIN 931 / DIN 933 — the German standards for part-threaded and fully threaded hex bolts, widely used across European industry.
- ASTM F675 — a standard referenced for titanium fasteners; compliance is confirmed per order against the specific part and grade.
- GB/T — the Chinese fastener standards, relevant where a project mixes GB and international components.
- Customer drawings — non-standard studs, spacers and bespoke parts.
We reference these standards to describe the dimensional system and the material context of a fastener. A fastener that matches a standard's dimensions is not the same thing as a fastener certified under that standard, and where certification is required it is confirmed in the quotation.
Grades and strength
| Grade | Nominal strength level | Typical use |
|---|---|---|
| Grade 2 (CP Ti) | Min. 345 MPa tensile | Seawater and chemical service where the environment, not the load, is the driver |
| Grade 5 (Ti-6Al-4V) | Min. 895 MPa tensile | Load-bearing joints, motorsport, weight-critical assemblies |
| Grade 23 (Ti-6Al-4V ELI) | Min. 860 MPa tensile, controlled interstitials | Precision and regulated applications where the ELI grade is called up |
Tensile values are standard minimums from the relevant ASTM specification, not measured results for a specific batch, and are given for guidance in choosing a grade.
Mixed-size ordering and sample packs
This is the part of the fastener business where a one-stop supplier is genuinely different. If you need twenty of one size, fifty of another, and a handful of a third, that is an order we will quote as one requisition. For a first purchase, a small mixed pack is often the sensible way to check thread quality and fit before committing to production quantities.
Marine and motorsport context
Marine is the largest single use, because titanium threaded rod, studs and U-bolts solve the problem of fasteners that corrode faster than the structure they hold. Motorsport and performance applications use Grade 5 where reducing unsprung or rotating mass matters.

A repeat-order context
A European welding and fabrication business has placed repeat orders covering Grade 2 threaded rod with matching nuts in a fine metric thread, alongside machined parts and tube on the same purchase orders. Repeat business on small fasteners like this is the pattern a comprehensive supplier is built for, since the quantities are well below what a mill would schedule.
