Professional Applications & Engineering Value
This M16 set screw is engineered from high-strength alloy steel to address critical challenges in heavy-duty machinery, automotive assemblies, and industrial equipment. The headless design with hex drive provides a flush finish, eliminating interference in compact spaces while allowing high torque application. Its cup tip creates a strong bite into shafts and collars, resisting rotational forces and vibration-induced loosening—common issues in dynamic operational environments. The metric coarse thread (M16x2mm) ensures rapid installation and reliable performance under repetitive load cycles. Complying with DIN 916 and ISO 4029, this set screw delivers consistent dimensional precision, making it a trusted component for OEMs and maintenance teams requiring durable, standards-aligned fastening solutions.
Specification Summary & Compliance
This set screw features a metric M16x2mm coarse thread with Class 5g6g thread fit per ISO standards, ensuring precise tolerances for reliable assembly. Manufactured to meet DIN 916 (ISO 4029) specifications, it guarantees dimensional accuracy and performance consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), adhering to environmental and safety regulations for industrial use.
