Professional Applications & Engineering Value

This alloy steel set screw with M5 coarse thread and 120° cone point addresses critical engineering challenges in precision assembly applications. The headless hex drive configuration enables flush mounting in confined spaces while maintaining high torque capability. The Rockwell C45 hardness ensures the screw maintains its structural integrity under vibrational stresses common in machinery, automotive components, and precision equipment. The cone point design provides superior biting action into shaft materials, preventing slippage in pulley systems, gear assemblies, and coupling applications. Manufactured to DIN 914 and ISO 4027 standards, this metric set screw delivers consistent performance in international projects requiring reliable positional locking solutions.
