Titanium Grade 4 Fasteners are commercially pure titanium fasteners identified as UNS R50700 and Werkstoff 3.7065 / DIN 3.7065. They offer the highest strength among the commercially pure titanium grades while retaining titanium's low density and excellent corrosion resistance. We supply Titanium Grade 4 bolts, nuts, screws, studs, washers, flange bolts and U-bolts for demanding applications in chemical processing, marine, aerospace, medical and industrial equipment.
What Are Titanium Grade 4 Fasteners?
Titanium Grade 4 Fasteners are made from commercially pure titanium and are designed for applications requiring a combination of high strength, low weight and corrosion resistance. ASTM identifies Grade 4 as UNS R50700, while commonly used international designations include 3.7065 and DIN 3.7065. ASTM B348 covers Grade 4 titanium bars and billets, while ASTM F468 covers commercial wrought nonferrous bolts, hex cap screws, studs and socket head cap screws for general service applications.
Compared with other commercially pure titanium grades, Grade 4 provides increased strength. Its higher allowable oxygen and iron levels contribute to its higher strength while the material remains classified as unalloyed titanium.
We manufacture and supply Commercially Pure Titanium Grade 4 Bolts, CP Grade 4 Titanium Screws and Fasteners, studs, nuts, washers and specialty fasteners in different sizes, thread configurations and head styles according to project requirements.

Why Choose Highest Strength CP Titanium Grade 4 Fasteners?
- Highest Strength CP Titanium Grade 4 Fasteners are selected when commercially pure titanium is preferred but greater strength is needed than is normally associated with the lower CP grades.
- High Strength-to-Weight Ratio: Titanium Grade 4 combines relatively low density with high strength, making it useful where weight reduction is important.
- Excellent Corrosion Resistance: Grade 4 titanium provides strong resistance to corrosion in many demanding environments, including seawater and several chemical environments.
- Lightweight Construction: At approximately 4.51 g/cm³, titanium is significantly lighter than many commonly used engineering metals.
- Good Fabrication Characteristics: Commercially pure Grade 4 titanium can be manufactured into bars, wire, forgings and other forms used for producing fasteners.
- Suitable for Specialized Applications: Its combination of strength, corrosion resistance and low weight makes Grade 4 suitable for selected aerospace, chemical, marine, medical and industrial applications.
Applications of Titanium Grade 4 Fasteners
Titanium Grade 4 Fasteners are used where conventional steel or other materials may not provide the required combination of weight and corrosion performance.
Common applications include:
- Chemical processing equipment
- Marine and seawater equipment
- Aerospace components
- Heat exchangers
- Condenser systems
- Industrial piping assemblies
- Pharmaceutical equipment
- Medical equipment
- Cryogenic equipment
- Pump and valve assemblies
- Corrosive-service machinery
- Specialized structural connections
The suitability of Grade 4 should always be checked against the actual service temperature, chemical environment, loading conditions and applicable design code.
Titanium Grade 4 Fasteners Manufacturing Process
Titanium Grade 4 Fasteners Weight
Because titanium has a density of approximately 4.51 g/cm³, Grade 4 fasteners provide a useful weight advantage in applications where reducing assembly weight is important.
Actual fastener weight depends on diameter, length, head configuration, thread type and geometry.
| Fastener Type | Weight Factor |
|---|---|
| Hex Bolt | Depends on diameter and length |
| Flange Bolt | Depends on flange diameter and length |
| Stud Bolt | Depends on diameter and overall length |
| U-Bolt | Depends on rod diameter and bend dimensions |
| Socket Head Screw | Depends on head and body dimensions |
| Threaded Rod | Depends on diameter and cut length |
We can provide dimensional weight information based on the required fastener size and drawing.
