With a titanium content of ≥90%, these bolts and nuts are engineered for high-performance applications requiring exceptional strength and corrosion resistance. Each bolt is accompanied by 2 or 3 nuts, providing secure and reliable fastening across various industrial and mechanical settings. The 30 mm length is optimized for medium-scale assembly tasks where precision and durability are paramount, while the thread tolerance of 0.02 guarantees a precise fit that enhances overall stability and safety.

These fasteners are ideally suited for use with ISO 3506 A2-70 stainless steel bolts (SS304), offering excellent corrosion resistance and high tensile strength for outdoor and marine applications. Their compatibility with ASTM A320 L7 low temperature alloy steel bolts allows reliable performance in cryogenic environments, making them indispensable in the oil and gas industry, chemical processing plants, and other sectors where temperature fluctuations are critical.

The stud bolt and nut sets are specifically designed for ASME B16.5 flanges used in piping systems for pressure containment. The precise thread tolerance of 0.02 ensures a secure seal and prevents leakage in high-pressure environments such as power plants, refineries, and water treatment facilities. Multiple nuts per bolt enhance the locking mechanism, providing extra safety against loosening due to vibrations or thermal expansion.

The product’s versatility extends to automotive, aerospace, and construction industries where reliability and performance are non-negotiable. Whether assembling critical engine components, securing structural elements, or fastening mechanical parts, these bolts and nuts deliver consistent quality. Their titanium-rich composition reduces weight while increasing resistance to wear and corrosion, extending the lifespan of fastened assemblies.

We offer extensive customization services to meet your specific project requirements. The standard length of the bolts is 30 mm with a small hole diameter of 12 mm, ensuring compatibility with various applications. All products comply with ISO 898-1 standards, guaranteeing high quality and performance.
