Professional Applications & Engineering Value

This M4 set screw delivers critical engineering solutions where space constraints and vibration resistance are paramount. The alloy steel construction with Rockwell C45 hardness provides exceptional shear strength, preventing failure in high-stress applications like machinery components, automotive assemblies, and precision equipment. The headless design with 2mm hex drive enables installation in confined spaces while maintaining sufficient torque capability. The coarse thread pitch (0.7mm) ensures rapid installation and superior resistance to vibrational loosening compared to fine-thread alternatives. The cup tip creates concentrated pressure points for secure positioning of gears, pulleys, and collars on shafts, solving common alignment and slippage issues in industrial settings.

Specification Summary & Compliance

This metric set screw features M4x0.7mm coarse threads with Class 6g tolerance per ISO metric standards, ensuring precise fit and reliable performance.
