- Material
- Grade 2 / UNS R50400
- Forms
- Hex head bolts, fully or partially threaded, with hex nuts
- Threads
- Metric, UNC, UNF or drawing
- Documents
- MTC, dimensions, thread inspection and traceability
Product Detail
Product Introduction
Grade 2 titanium hex bolts and nuts are selected primarily for corrosion resistance, ductility and low mass. The joint definition must state geometry, thread system and fit, grip and engagement, mating materials, load, lubricant or anti-galling treatment, service environment and finished-fastener acceptance.
Product Specifications
| Product | Grade 2 Titanium Hex Bolts and Nuts | Material | Titanium Grade 2 / UNS R50400 |
|---|---|---|---|
| Product Form | Standard or drawing-specific titanium fastener | Typical Inquiry Range | Metric, inch and custom sizes confirmed at RFQ stage |
| Dimensional References | Expressly invoked standard or approved drawing | Threads / Dimensions | Metric coarse or fine, UNC, UNF or drawing-specific as applicable |
| Surface | Machined and cleaned; lubricant, anti-galling treatment or coating by agreement | Documents | MTC, heat/lot traceability and dimensional inspection report |
| Inspection | Dimensions, thread gauging, surface and agreed functional or mechanical tests | Supply Basis | Approved purchase order, invoked standard and drawing |
Typical inquiry ranges are not a stock guarantee. Final manufacturability, tolerances and test requirements are confirmed against the complete RFQ.
Selection and Configuration
- Bolt and nut geometry: Specify the invoked dimensional standard, thread, bolt length, threaded length, nut style and across-flats dimensions.
- Corrosion environment: Confirm process media, chloride exposure, temperature and galvanic contact with other metals.
- Installation control: Define lubrication, anti-galling treatment, tightening method and permitted reuse.

Chemical Composition – Titanium Grade 2
Maximum weight percent unless shown otherwise; titanium is the balance.
| N max | C max | H max | Fe max | O max | Residual each / total | Ti |
|---|---|---|---|---|---|---|
| 0.03 | 0.08 | 0.015 | 0.30 | 0.25 | 0.10 / 0.40 | Balance |
Mechanical Properties – Grade 2 Material Reference
| Property | Annealed Grade 2 Material Reference Minimum |
|---|---|
| Ultimate tensile strength | 345 MPa (50 ksi) |
| 0.2% yield strength | 275 MPa (40 ksi) |
| Elongation | 20% |
Material values do not automatically establish finished-fastener loadability. Finished-part acceptance depends on geometry, manufacturing route, condition and the expressly invoked fastener specification or drawing.
