  2. Wire Drawing: The raw wire rod is drawn through a series of dies to achieve the precise diameter required for the bolt's shank, enhancing its strength and surface finish.
  3. Cold Heading/Forging: Using high-speed cold heading machines, the wire is cut to length, and the bolt head is formed. For larger or more complex bolts, hot forging may be employed. This process work-hardens the material, improving mechanical properties.
  4. Thread Rolling: Rather than cutting, threads are typically rolled onto the bolt shank. This process rearranges the material's grain structure, increasing fatigue strength and resistance to stripping, a significant advantage over cut threads.
  5. Heat Treatment: Bolts undergo specific heat treatment processes (e.g., quenching and tempering) to achieve the desired hardness, tensile strength, and ductility as per material specifications (e.g., A193 B7 for high-temperature applications).
  6. Surface Finishing/Coating: Depending on application requirements, bolts are cleaned and coated. Common finishes include zinc plating (for corrosion resistance), hot-dip galvanizing, or specialized PTFE (e.g., Xylan, Fluorokote) coatings for enhanced corrosion resistance and reduced friction, often seen with color stud bolts.
  7. Quality Control & Testing: Throughout the process, and especially as a final step, bolts undergo rigorous testing. This includes dimensional checks, mechanical property tests (tensile, yield, hardness, impact), chemical analysis, non-destructive testing (NDT), and coating thickness verification.
  8. Packaging & Certification: Finished bolts are packaged to prevent damage during transit, often with protective coatings or inhibitors. Comprehensive material test reports (MTRs) and certifications (e.g., ISO 9001, PED, API) accompany shipments, assuring traceability and compliance.
