Knurled dowel pins are precision-engineered locating pins designed to provide strong retention force through a knurled (serrated) surface. The knurled pattern increases friction inside the mating hole, ensuring a tight, vibration-resistant fit without additional locking components.

As a professional industrial fastener supplier, JLHY produces high-precision knurled dowel pins widely used in automotive assemblies, mold tooling, machinery manufacturing, electronics fixtures, and precision equipment alignment applications.

These pins are ideal where consistent positioning, high holding power, and repeatable assembly performance are required.
