This cold working process improves the grain structure of the metal, increasing the bolt's strength and fatigue resistance without material loss, a key advantage over traditional casting.
4. Thread Rolling: Threads are formed by rolling the blank between two dies. This method results in stronger threads than cut threads because it doesn't remove material and instead compacts the grain structure, enhancing fatigue strength and resistance to stripping.
5. Heat Treatment: For high-strength bolts (Grade 8.8, 10.9, 12.9), a precise heat treatment process involving quenching and tempering is applied. This optimizes the bolt’s microstructure, achieving the specified tensile strength, yield strength, and hardness, while minimizing risks such as hydrogen embrittlement.
6. Surface Treatment:
   • Black Oxide: A conversion coating providing mild corrosion resistance and a matte black finish.
   • Electro-galvanizing (Zinc Plating): Applying a thin layer of zinc for moderate corrosion protection. Often used for zinc plated self drilling screws manufacturer products as well.
   • Hot-Dip Galvanizing (HDG): Immersion in molten zinc, creating a thick, durable, and highly corrosion-resistant coating suitable for harsh outdoor and marine environments. This significantly extends service life, leading to energy saving through reduced maintenance cycles.
   • Other coatings: Dacromet, Geomet, PTFE for specialized applications.
7. Quality Control & Testing: Throughout the entire process, rigorous testing is conducted, including dimensional checks (using gauges, calipers), mechanical property tests (tensile strength, proof load, hardness), metallurgical analysis, and corrosion resistance tests (salt spray testing per ASTM B117). This adherence to standards like ISO, ANSI, and ASTM is vital for ensuring consistency and reliability.
8. Packaging & Shipment: Bolts are carefully packaged to prevent damage during transit and labeled for easy identification and traceability, a hallmark of reliable wire bolts exporters.

This meticulous manufacturing regimen ensures that the finished bolts meet precise technical specifications and deliver superior performance in demanding applications, ultimately enhancing structural integrity and providing exceptional service life. Target industries include petrochemical (where corrosion resistance is critical), metallurgy (high-temperature and load-bearing applications), water supply & drainage (ensuring leak-proof and durable connections), construction, and heavy machinery.
