Custom CNC Swiss Turned 304 Stainless Steel Umbrella Rib Shaft Pin Bone Locating Pin Middle Shaft Pin with Knurled End
Product DescriptionThis custom CNC swiss lathe umbrella pin, also named umbrella bone locating pin or umbrella middle shaft pin, is precision turned from 304 stainless steel. The tail section features knurling for anti-slip performance to lock umbrella ribs firmly inside umbrella frames.
Adopting swiss type CNC turning process, all machining operations including cutting, outer diameter turning, tail knurling, cutoff, deburring and polishing are finished in one single clamping setup to ensure consistent dimensional accuracy. Surface is natural stainless steel polished finish without coating.
As a professional manufacturer, we provide OEM & custom service. We can produce custom cnc turned umbrella parts according to your drawings or samples, including various size, material, surface finish for umbrella hardware assemblies.
