Professional Applications & Engineering Value
This M6 countersunk washer is engineered to address common industrial challenges such as surface protrusion and uneven load bearing. Crafted from aluminum, it offers a lightweight yet robust solution for applications in aerospace, electronics, and machinery where weight reduction is critical. The 90° countersink angle ensures a flush mount with M6 screws, eliminating snag points and improving aerodynamic or aesthetic profiles. Its metric dimensions (6.4mm ID, 18mm OD) provide reliable alignment and stress distribution, reducing the risk of loosening under dynamic loads. Ideal for industrial washers used in assembly lines or outdoor equipment, this component delivers consistent performance while meeting stringent RoHS and REACH environmental standards.
Specification Summary & Compliance
This washer adheres to metric system specifications, including a 6.4mm inner diameter and 18mm outer diameter with a 90° countersink angle for precise fit. It is manufactured from aluminum with an overall height of 3.3mm, ensuring dimensional accuracy for M6 screw applications. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted substances and suitable for global industrial use.
