Metric Dowel Pins

Metric Dowel Pins are high-precision fasteners widely used for accurate alignment and secure fastening in molds, jigs, mechanical structures, and automated machinery. Available in carbon steel, stainless steel, brass, and aluminum, with customizable tolerances (h6/h7/m6), heat treatment, and surface finishes such as zinc plating, passivation, and black oxide.
Compliant with multiple international standards (DIN 6325, ISO 8734, ISO 2338), these pins are ideal for precision assembly in electronics, semiconductor equipment, medical devices, and aerospace manufacturing, with options for quick delivery and special-size production.
