• Extended 15mm tip design provides deeper penetration and enhanced grip strength for critical positioning applications
• External square drive system delivers superior torque transmission and prevents tool slippage during high-tension installations
• Full regulatory compliance with DIN 479 specifications plus RoHS 3 and REACH environmental standards for global manufacturing acceptance
• Optimized dimensional stability with precise tip diameter (15mm) and length (80mm) tolerances ensuring consistent performance in repetitive assemblies
• Right-hand thread configuration with 2.5mm pitch for standard industrial compatibility and simplified maintenance procedures

Professional Applications & Engineering Value

This M20 metric set screw delivers critical engineering solutions for heavy-duty industrial applications where component positioning and vibration resistance are paramount. The alloy steel construction with Rockwell C23 hardness provides exceptional shear strength for machinery assemblies, conveyor systems, and permanent fixture applications. The extended tip design (5.3mm projection) creates positive locating points in shafts and collars, while the coarse metric thread with Class 6g fit ensures rapid installation without compromising retention strength. The square head configuration with external drive accommodates high-torque applications where socket heads might strip, making it ideal for maintenance-critical environments and equipment requiring periodic adjustment.

Specification Summary & Compliance

Manufactured to DIN 479 specifications with Class 6g thread tolerance ensuring precision metric threading compatibility. The extended tip maintains strict dimensional control with diameter tolerance of -0.27mm to 0 and length tolerance of -0.3mm to 0. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees suitability for international industrial applications and manufacturing requirements.
