Key Advantages of Cold Forged Fasteners
Multi-Station Cold Heading
Successive forming operations produce defined head profiles, shoulders, grooves, and other component features while reducing material waste compared with machining the entire part from solid stock.
Integrated Thread Rolling
Thread rolling creates external threads through material deformation, supporting repeatable thread geometry for fasteners designed to meet specified dimensional and mechanical requirements.
Dedicated Inspection Equipment
Jieyi lists dimensional measuring instruments, hardness testers, tensile and torque testing equipment, and salt spray testing equipment to support component inspection against applicable specifications.
Secondary Processing Options
CNC machining, grinding, heat treatment, and surface finishing can be incorporated where required by the component design and confirmed manufacturing capabilities.

Frequently Asked Questions
Can Jieyi manufacture cold forged fasteners from drawings?
-
Yes. Jieyi accepts drawings and samples for non-standard fasteners and formed metal components. Manufacturing feasibility depends on the geometry, material, tolerances, and required production process.
Which materials can be used?
-
Material selection depends on the component design and required mechanical properties. Specify the material grade or applicable standard so availability and forming suitability can be evaluated.
Can custom threads and surface treatments be specified?
-
Yes. Thread dimensions and finishing requirements can be included in the technical drawing. Available surface treatments should be confirmed against the required coating specification and corrosion performance.
What quality documents can Jieyi provide?
-
Jieyi lists ISO and IATF 16949 certifications and uses automotive quality planning methods including APQP, PPAP, and FMEA. Confirm the current certification scope and project-specific inspection or documentation requirements before ordering.
