Professional Applications & Engineering Value

This M1.6 set screw delivers critical performance in precision assemblies where space constraints and vibration resistance are paramount. The alloy steel composition combined with Rockwell C45 hardness provides exceptional shear strength and wear resistance, preventing loosening under dynamic loads. The hex drive design ensures reliable torque transmission without cam-out, while the cup tip creates concentrated contact pressure for superior axial positioning in shafts, collars, and gears. Ideal for metric thread applications in electronics, automotive components, and precision machinery, this headless set screw solves alignment challenges while maintaining compact design integrity.
