Titanium Hexagon Head Bolts

Titanium, with its unique combination of properties—its density is approximately 60% that of steel, yet it possesses strength comparable to high-quality alloy steel, with a tensile strength of 800-1200 MPa; its excellent corrosion resistance, withstanding corrosion from various acids, alkalis, and marine salt spray environments; and its excellent high- and low-temperature performance, maintaining stable mechanical properties in temperatures ranging from -253°C to 500°C—makes it an ideal alternative to traditional bolt materials.

Titanium hexagonal head bolts, a hallmark of titanium parts, feature a standardized hexagonal head design compatible with universal wrenches and convenient operation, playing an irreplaceable role in a wide range of mechanical connection scenarios. From aircraft wing assembly to chassis fastening for luxury supercars, from connecting the pressure hulls of deep-sea research equipment to the precision assembly of high-end electronic equipment, titanium hexagonal head bolts are reshaping the industry standard for fastening connections with their exceptional performance.

Manufacturing Titanium Hexagon Bolts

Wstitanium’s manufacturing technology is a comprehensive manufacturing solution that integrates advanced materials science, precision CNC machining, and quality control systems.

Wstitanium precisely matches titanium alloy grades for different applications. For example, TC4 (Ti-6Al-4V) is used in general industrial applications requiring both strength and toughness, while TB6 (Ti-10V-2Fe-3Al) is suitable for critical aerospace components requiring both high strength and fracture toughness. A 5-axis CNC machining center is used for high-precision forming of complex shapes, achieving positioning accuracy of ±0.005mm and ensuring bolt dimensional tolerances are strictly controlled within ±0.01mm.

To further enhance the corrosion resistance, wear resistance, and appearance of titanium hexagon bolts, various surface treatment options are available.

Anodizing: The bolt is placed in a specific electrolyte, acting as the anode. An electrolytic reaction creates an oxide film 5-10μm thick on the surface. This coating not only effectively improves corrosion resistance but also comes in various colors, such as golden and blue, to meet personalized decorative needs.

PVD Coating: For applications requiring extremely high wear resistance, physical vapor deposition (PVD) technology is used to deposit a 1-3μm thick hard coating of TiN, TiAlN, or other materials on the oxide film surface. The coating can achieve a hardness of HV2000-3000, significantly improving surface wear and scratch resistance.

Applications of Titanium Hexagonal Bolts

As high-performance fasteners, titanium hexagonal bolts play an irreplaceable role in multiple key industries thanks to their exceptional advantages in lightweighting, high strength, corrosion resistance, and biocompatibility.

(I) Aerospace

Titanium hexagonal bolts, with their exceptional lightweight and high-strength properties, are widely used in critical applications such as fuselage structural connections, wing assembly, and engine component fastening. For example, the Boeing 787 Dreamliner uses over 100,000 titanium alloy fasteners (including titanium hexagonal bolts), accounting for 20%-25% of the total fastener count.

(II) Automotive

In the manufacture of high-end luxury cars and supercars, titanium hexagonal bolts are key components for enhancing vehicle performance, as seen in some models from brands like Ferrari and Lamborghini. Titanium bolts connect suspension systems, brake systems, and engine blocks, enhancing suspension responsiveness and handling. Available in various anodized colors, such as gold, blue, and black, they complement custom wheels and vehicle paint jobs, showcasing a unique and refined aesthetic.

(III) Marine

Titanium hexagonal bolts, with their excellent resistance to seawater corrosion, are widely used in offshore platform construction, ship structural connections, and seawater treatment equipment. Titanium bolts are used to connect the main structure of drilling platforms, drilling equipment, and support frames. In shipbuilding, titanium hexagonal bolts are used to connect components such as hulls, decks, and engine bases.
