Knurled Dowel Pin

Knurled dowel pins feature a textured knurled surface designed to create interference and friction during insertion. The knurled section provides slight expansion and surface grip, resulting in secure press-fit installation without the need for threads or fasteners.

This makes them ideal for fast assembly and high-efficiency production lines, especially in plastic parts, aluminum components, and other light metal assemblies.
