Our stainless steel knurled round head positioning screw is a one-piece CNC turning precision machined component custom manufactured for industrial fixture and tooling positioning. We process solid 304 stainless steel bar raw material through dedicated diamond knurling, CNC lathe forming of full thread and smooth round dome head, followed by full deburring, ultrasonic cleaning and bright passivation surface treatment. The middle knurled section delivers friction anti-slip grip for manual adjustment without extra tools, while uniform external threads and smooth round locating head guarantee stable, repeatable positioning performance on jigs, assembly fixtures and automated equipment. As a professional CNC turning OEM manufacturer, we accept fully customized dimensional, material and surface finish modifications per your engineering drawings or physical samples. All finished studs hold strict precision dimensional tolerances to meet high-precision industrial assembly requirements.
