• Exceptional durability achieved through Rockwell C45 hardened alloy steel construction that resists wear and deformation
• Precise thread engagement with Class 5g6g tolerance ensuring consistent fit and reliable performance in demanding applications
• Easy installation and removal with 8mm hex drive that provides excellent torque transmission without head protrusion
• Optimized for industrial environments featuring coarse 2mm pitch threads that resist loosening under vibration and dynamic loads
• Global compliance assurance meeting DIN 916/ISO 4029 standards for consistent quality and international project specifications
• Environmentally responsible manufacturing with full RoHS 3 and REACH compliance for sustainable procurement

Professional Applications & Engineering Value

This M16 set screw delivers critical engineering solutions where space constraints and vibration resistance are paramount. The headless design with hex drive allows for flush mounting in tight assemblies while maintaining excellent torque capability. Manufactured from alloy steel with Rockwell C45 hardness, this fastener withstands repeated adjustments without thread deformation. The cup point creates permanent indentation in shaft components, preventing rotational slippage in power transmission systems, machinery collars, and gear assemblies. The coarse 2mm pitch metric threads provide rapid installation and superior resistance to vibrational loosening in industrial equipment, automotive components, and heavy machinery where reliability is non-negotiable.

Specification Summary & Compliance

This metric set screw features M16x2mm dimensions with Class 5g6g thread fit per ISO standards, ensuring precise dimensional accuracy for consistent performance. Manufactured to DIN 916/ISO 4029 specifications, the fastener delivers reliable mechanical properties and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations, making it suitable for global supply chains and environmentally conscious manufacturing operations.
