• Regulatory compliance assurance meeting ASME B18.3, RoHS 3, and REACH standards for global project suitability

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical engineering advantages in precision assemblies where vibration resistance and corrosion protection are paramount. The Class 3A UNF fine threads maintain tight tolerances in high-cycle equipment, while the 90° cone point generates superior clamping force on shafts and collars. Ideal for headless fastening in robotics, automotive components, and industrial machinery, it eliminates protrusion issues in compact designs. The Rockwell C45 hardness ensures dimensional stability under repetitive stress, making it a reliable choice for permanent installations requiring set screw integrity.
