Application of Machinery and Equipment Materials
Cold‑formed materials for mechanical connections and assemblies. For bolts, screws, and special‑shape parts, assess material options in light of part geometry, forming processes, and subsequent heat‑treatment requirements.
Fastener components
For material inquiries regarding mechanical fasteners such as bolts and screws, please specify the head configuration, shank dimensions, cold heading process, and subsequent threading requirements.
Irregular‑section parts
For parts with complex geometries, an irregular‑section solution can be evaluated in conjunction with the existing round‑wire processing route. Whether this approach reduces the number of operations must be confirmed through forming validation on the specific part.

This case involves rotary cold heading. The material must balance low hardness prior to forming with high hardness after heat treatment.
According to the Group’s promotional materials, the requirements for this case are: cold heading wire with HRB ≤ 65, and a final product hardness of HRC ≥ 60 after heat treatment. These two specifications correspond to different process states and apply only to this particular case; they should not be used as general guarantees for all wire grades.
