• Durable Material Construction - Steel composition with Rockwell C20 hardness maintains structural integrity in demanding industrial environments
• Secure Installation & Removal - External hex drive with 10mm head width offers excellent torque transmission and tool accessibility
• Regulatory Compliance Assurance - Meets DIN 561B specifications while being RoHS 3 and REACH compliant for global market acceptance
• Precision Manufacturing - Tight tip length (0 to 0.3mm) and diameter (-0.18mm to 0) tolerances ensure consistent performance across production runs

Professional Applications & Engineering Value

This M8 set screw with extended tip design addresses critical challenges in industrial assembly where component slippage and positional accuracy are paramount. The Class 8.8 steel construction provides exceptional shear strength for machinery components, while the coarse thread configuration (1.25mm pitch) ensures rapid installation in time-sensitive manufacturing environments. The external hex drive facilitates high-torque applications without stripping, making it ideal for industrial set screws requirements in automotive jigs, conveyor systems, and precision equipment. The extended tip's controlled diameter (5.5mm) creates positive locating points, eliminating the need for additional alignment fixtures and reducing assembly time by up to 30% in repetitive fastening operations.

Specification Summary & Compliance

Manufactured to DIN 561B standards with Class 6g thread fit tolerance for precision engagement. The 25mm length features right-hand metric threads with controlled tip dimensions (length tolerance: 0 to 0.3mm, diameter tolerance: -0.18mm to 0). Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and international market suitability. The Rockwell C20 hardness rating confirms consistent mechanical properties across production batches.
