Assortment of Machined Shafts with Metal Dowel Pins and Long Cylindrical Rods

Material selection for metal dowel pins determines wear resistance in the mating bore and resistance to bending when used as a shear pin; case-hardened carbon steel provides the surface hardness needed for press-fit locating pins in repeated assembly and disassembly jigs, while stainless steel is specified for dowel pins in medical and food-processing assemblies where rust marks on the bore surface are a contamination concern. Dongguan Jiarui Hardware Technology (Dongguan, Guangdong, founded 2012) turns and grinds these metal dowel pins with long cylindrical profile using turning, Swiss machining, and external cylindrical grinding at their around 2,500 m² Dongguan facility, with pin OD fit class, cylindricity, and finish quality Ra cross-checked with your specification at first-off sign-off. IATF 16949 and ISO 9001 certifications govern traceability for automotive, aerospace, fasteners, and general industry metal dowel pin applications. We can quote once we have OD fit class, length, cylindricity requirement, and material specification from your drawing.
