Aluminium Knob with Spherical Finial Knob and Ball Head, Short Threaded Stem

Aluminium alloy and surface treatment selection for a spherical finial knob with ball head and threaded stem determines grip texture durability and thread engagement depth; anodised 6061-T6 provides the surface hardness for repeated hand-contact wear in medical equipment and musical instrument applications, while clear anodise preserves the visual appearance of the ball head over the product's service life. Suzhou Dingqian Energy Industry (Suzhou, Jiangsu, established 2018) CNC-turns this aluminium spherical finial knob with ball head and short threaded stem using turning and milling at their an estimated 7,000 m² Suzhou facility, with ball diameter, thread class, and stem length confirmed using your drawing as reference during in-process inspection. ISO 9001 certification covers musical instruments, medical equipment, outdoor recreation, and contract manufacturing spherical finial knob applications. For quoting, include ball diameter, thread specification, stem length, and aluminium grade so our Suzhou team can quote the job. Output serves automotive, aerospace, and military buyers.
