Professional Applications & Engineering Value
This M5 hex headless set screw is engineered to address common industrial challenges, such as component slippage and corrosion-induced failure. Made from 18-8 stainless steel, it offers excellent resistance to rust and oxidation, making it ideal for machinery, automotive assemblies, and outdoor equipment. The cup tip provides a concentrated point of contact, reducing the risk of loosening under vibration, while the vented design allows for pressure release in sealed systems. With a coarse metric thread and Class 6g fit, it ensures quick, accurate installation, minimizing downtime in production lines. This screw is a reliable choice for securing collars, gears, and pulleys where durability and precision are critical.
Specification Summary & Compliance
This set screw adheres to metric system standards with an M5 thread size, 0.8mm pitch, and 8mm length. The thread fit is Class 6g, providing standard tolerance for general use, and it features a right-hand, coarse thread type. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it meets environmental and safety requirements for industrial applications.
