Professional Applications & Engineering Value

This 316 Stainless Steel hex headless set screw is engineered to address critical challenges in precision assembly and machinery. Its UNC coarse thread and Class 3A thread fit deliver high clamping force and vibration resistance, preventing loosening in dynamic applications like motor shafts, pulleys, and gear assemblies. The headless design with a 3/16" hex drive allows for a flush installation, eliminating protrusions in compact spaces while the cup tip bites securely into components without causing excessive damage. Made from corrosion-resistant 316 stainless steel and hardened to Rockwell B80, it excels in demanding environments—including marine, chemical processing, and outdoor equipment—where durability and long-term reliability are paramount. This set screw ensures consistent performance, reduces maintenance needs, and supports efficient production workflows.
