Long Cylindrical Pin Shaft with Metal Dowel Pin and Turned Shoulder Feature

Chongqing Jiangjin Changfeng Precision Machining (Chongqing, established 2001, Degan Industrial Park, close to 20,000 m²) turns metal dowel pins with turned shoulder feature using turning and wire EDM, with pin OD fit class, shoulder concentricity, and finish quality Ra verified against your released print at first article sign-off and confirmed in batch sampling before shipment. Changfeng's aerospace and military production traceability requirements make pin OD fit class and cylindricity a documented, inspected output on every order. A metal dowel pin with OD outside the m6 tolerance field either prevents press-fit insertion or rocks in the locating bore under shear load. ISO 9001 certification covers aerospace, automotive, and military metal dowel pin applications. Provide pin OD fit class, shoulder dimensions, surface finish Ra, and material specification and your drawing for quoting. For a turning proposal from our chongqing facility.
