Titanium Fasteners

Our Titanium Fasteners are high-performance industrial fastening components, precision manufactured from high-purity commercially pure titanium and aerospace-grade titanium alloys via multi-axis CNC machining, cold heading and hot forging processes. They fully inherit titanium's inherent core advantages: 40% lighter than steel, exceptional corrosion resistance, ultra-high strength-to-weight ratio, excellent biocompatibility and non-magnetic properties, making them the ideal upgrade replacement for stainless steel, carbon steel and alloy steel fasteners in harsh working conditions.

All our titanium fasteners undergo strict full-process quality control, with 100% traceability from raw material melt batch to finished product, ensuring consistent mechanical properties, dimensional accuracy and corrosion resistance for every single fastener.

1.Superior Material Performance & Grade Coverage : 

We provide a full range of commercially pure titanium and titanium alloy grades, from general-purpose Grade 2 to aerospace Grade 5 (Ti-6Al-4V), medical Grade 23 (Ti-6Al-4V ELI), and corrosion-resistant Grade 7. All raw materials comply with ASTM B348, ASTM F136 and AMS standards, with ultra-low impurity control, ensuring the fasteners maintain stable mechanical properties and corrosion resistance in the harshest working environments.

2.Full International Standard Compliance : 

Our titanium fasteners are manufactured in strict accordance with all mainstream international standards, including ANSI/ASME, ISO, DIN, JIS and GB. We provide full thread coverage (metric M series, imperial UNC/UNF, BSW, BSP, NPT), complete tolerance grades, and full compatibility with global standard fastening systems, making them a direct drop-in replacement for steel and stainless steel fasteners in your projects.

3.Precision Manufacturing & Tight Tolerance Control : 

Adopt advanced cold heading, hot forging and 5-axis CNC machining technology, with thread rolling after heat treatment for superior thread strength and wear resistance. Dimensional tolerance is strictly controlled within ISO 4759-1 standard, with thread tolerance 6g/6H (metric) and 2A/2B (imperial) as standard, with custom precision tolerance up to 4H/4g available. No burrs, sharp edges or surface defects, ensuring perfect fit and smooth installation.

4.Industry-Leading Corrosion Resistance : 

Unparalleled corrosion resistance in the harshest environments: excellent resistance to pitting, crevice corrosion, intergranular corrosion and stress corrosion cracking in seawater, high chloride ion brine, strong oxidizing acids (nitric acid, chromic acid), alkalis, organic acids and sour crude oil media. Standard Grade 2 titanium fasteners outperform 316L stainless steel in 90% of corrosive conditions; Grade 7 titanium fasteners with palladium addition provide exceptional corrosion resistance in extreme reducing acid (hydrochloric acid, sulfuric acid) and high-temperature brine environments, suitable for the most demanding chemical and offshore applications.

5.Ultra-Lightweight & High Strength-to-Weight Ratio : 

Titanium has a density of only 4.51g/cm³, 40% lighter than steel, but with comparable tensile strength to high-strength alloy steel. Our titanium fasteners significantly reduce the overall weight of equipment and structures, which is critical for aerospace, racing, marine and renewable energy applications where weight reduction directly improves performance, energy efficiency and load capacity.

6.Wide Temperature & Special Performance Adaptability : 

Maintain excellent mechanical properties in an ultra-wide working temperature range from -253℃ (cryogenic environment) to 450℃. No brittleness at ultra-low temperatures, no strength degradation at high temperatures, fully adapting to cryogenic engineering, aerospace and high-temperature industrial applications. In addition, titanium is completely non-magnetic, making our fasteners ideal for semiconductor, medical imaging, navigation and electronic equipment where magnetic interference must be eliminated.

7.Excellent Biocompatibility & Medical Grade Compliance : 

Our medical grade titanium fasteners (Grade 1, Grade 4, Grade 23 ELI) are manufactured in an ISO 13485 certified clean workshop, fully compliant with ASTM F136, ISO 10993 and FDA standards. Non-toxic, non-cytotoxic, no allergic reaction, excellent osseointegration performance, ideal for orthopedic implants, dental prosthetics, surgical instruments and medical device assembly.

8.Anti-Galling & Anti-Lock Design Optimization : 

Titanium fasteners are prone to galling (cold welding) during installation, we solve this pain point through multiple optimizations: precision rolled threads with smooth surface finish, optimized thread tolerance fit, and a variety of anti-galling surface treatment options (PVD coating, molybdenum disulfide coating, silver plating, PTFE coating). This effectively prevents thread lock and galling during installation and disassembly, ensuring repeated use without damage.
