Metal-Rubber Composite Dowel Pin | Metal Fixings And Fasteners | Automotive Fastener
Product Description
This Metal-Rubber Composite Dowel Pin is a high-performance fastening component designed for precision locating and vibration damping. Its cylindrical structure combines a rigid metal base (steel/stainless steel) for structural support and a black HNBR/NBR rubber top cap for shock absorption and sealing. The metal core ensures accurate alignment in mating assemblies, while the rubber cap absorbs mechanical vibration, reduces operational noise, and creates a barrier against dust and moisture. This dual-layer design makes it ideal for automotive chassis systems, industrial machinery, and heavy equipment where both precise positioning and vibration control are critical.
