Professional Applications & Engineering Value
This M16 x 2mm metric set screw is engineered to solve critical fastening challenges in industrial settings. The alloy steel material, hardened to Rockwell C45, provides excellent resistance to wear and deformation, making it ideal for high-stress applications like machinery, automotive components, and precision equipment. The cup tip design ensures a firm grip on shafts or hubs, preventing slippage and maintaining alignment under dynamic loads. With a coarse thread and Class 5g6g thread fit, it offers quick assembly and reliable performance in environments subject to vibration and thermal cycling. This headless screw with an 8 mm hex drive allows for flush mounting, reducing protrusion risks and enabling use in tight spaces where a secure, tamper-resistant fastening solution is essential.
Specification Summary & Compliance
This set screw features a metric M16 x 2mm coarse thread with Class 5g6g thread fit per ISO standards, ensuring precise dimensional accuracy. It complies with DIN 916 and ISO 4029 manufacturing specifications for consistent quality. Additionally, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to environmental and safety standards for industrial use.
