Threaded Fastener with Knurled Cylindrical Insert and Stainless Steel Construction

We supply this CNC-machined knurled cylindrical insert to support clean seating and repeatable mounting. For this knurled cylindrical insert, diameter tolerance, fit class, and surface finish are defined to suit your assembly targets. Share a detailed drawing when you need tighter callouts on press-fit or thread engagement. For controlled builds, we align inspection checkpoints with your released specification. In Jiangsu, our ISO 9001 line supports stainless steel fastener production. Unit pricing and lead time are set once we understand tolerance band, order quantity, and required quality documentation. This helps you plan repeatable supply for ongoing production programs, supporting automotive, aerospace, and railway projects.
