Professional Applications & Engineering Value

This M3 set screw is engineered to address critical challenges in precision assembly, such as securing gears, pulleys, and collars on shafts without protruding heads. The alloy steel material, combined with a Rockwell C45 hardness, provides high tensile strength and wear resistance, reducing the risk of stripping or deformation under torque. The 90° cone point concentrates pressure for a firm grip, minimizing loosening in dynamic systems. Its headless design and 1.5 mm hex drive allow for compact installations in machinery, automotive, and electronics, where space constraints and reliability are paramount. By adhering to DIN 914/ISO 4027 standards, it ensures seamless integration into global engineering projects, offering a dependable solution for industrial set screws that demand precision and longevity.
