Stepped Bore Component With Machined Brass Component and Lobed Asymmetric Profile

Automotive fastener assemblies, communication hardware, and energy storage module contacts use a machined brass component with lobed asymmetric profile where stepped bore diameter tolerance and lobe-to-lobe angular spacing together determine press-fit engagement and rotational indexing accuracy; stepped bore diameter above H6 tolerance reduces the interference fit on the mating shaft and allows the component to spin under rated torque, while lobe angular spacing outside ±0.3° prevents simultaneous contact of all lobes with the mating recess and concentrates load on the first engaged lobe face. Foshan Zhengshang Precision Hardware (Foshan, Guangdong, ISO 9001, ISO 14001, ISO 45001 certified) turns and mills this stepped bore machined brass component with lobed asymmetric profile at their 2,000 m² of production area Foshan facility using Swiss machining, milling & turning, and CNC milling, with stepped bore diameter, lobe angular spacing, and OD measured to match your print at the first article stage. Zhengshang serves automotive, medical equipment, drones, energy storage, and communication machined brass component applications. For pricing, provide stepped bore tolerance, lobe spacing, OD, and brass grade from your print.
