Professional Applications & Engineering Value
This M3 hex headless set screw delivers critical vibration-resistant fastening for precision assemblies where space constraints and reliability are paramount. The 18-8 stainless steel construction provides excellent corrosion resistance for industrial environments, while the permanent nylon patch thread locker eliminates the need for secondary locking components. The headless design with 1.5mm hex drive allows flush installation in confined spaces, making it ideal for machinery, automotive, and electronics applications where vibration resistance and metric coarse threading are essential. The cup tip distributes pressure evenly, preventing damage to shafts and components during securement.
Specification Summary & Compliance
This precision fastener features M3 x 0.5mm coarse thread with Class 6g thread fit and 4mm length, manufactured to DIN 916/ISO 4029 specifications. The component maintains Rockwell B80 hardness and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring both mechanical performance and regulatory adherence for global industrial applications.
