Dowel / Parallel Pin:3.5 x 40mm - DIN 7/Steel

This industrial fastener is a parallel pin constructed from durable steel, designed for secure mechanical alignment. It features a nominal diameter of 3.5mm and a total length of 40mm, conforming to the established DIN 7 standard. Such pins are widely utilized in machinery, automotive assemblies, and general engineering applications to fix parts in precise positional relationships. Engineers select these steel pins for their consistent strength and ability to maintain tight tolerances in dynamic environments. To ensure compatibility, verify that your pre-drilled holes match the 3.5mm diameter and that the engagement depth supports the full 40mm length.
