- Guaranteed quality and safety through full compliance with RoHS 3 and REACH environmental regulations
- Interchangeable precision meeting DIN 916 standards for consistent performance in metric assembly systems
Professional Applications & Engineering Value
This M2.5 set screw is engineered to address critical challenges in precision assembly and machinery. The alloy steel material and Rockwell C45 hardness provide exceptional resistance to wear and deformation, making it ideal for high-stress applications like motor shafts, gear assemblies, and precision instruments where set screws must maintain clamping force under continuous vibration. The headless design with hex drive allows for completely flush mounting in tight spaces, eliminating interference while the cup tip bites securely into shafts to prevent axial movement. Its coarse metric thread ensures rapid installation and superior resistance to loosening in dynamic industrial environments, providing reliable performance in automation equipment, electrical enclosures, and mechanical linkages where precision fastening is non-negotiable.
Specification Summary & Compliance
This metric set screw features M2.5 x 0.45mm coarse right-hand threads with Class 5g6g tolerance for precise fit, 12mm length, and is manufactured to DIN 916 specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use worldwide.
