• High durability and strength with Rockwell B80 hardness, resisting wear and deformation under load
• Easy installation in confined spaces using the 3/32" hex drive headless design for flush mounting
• Fine UNF thread spacing provides increased engagement and holding power in thin materials
• Full regulatory compliance with ASME B18.3 standards and environmental regulations including RoHS 3 & REACH

Professional Applications & Engineering Value

This 10-32 UNF Class 3A set screw delivers exceptional performance in precision engineering applications where vibration resistance and corrosion protection are critical. The 18-8 stainless steel composition combined with Rockwell B80 hardness ensures long-term reliability in demanding environments from marine equipment to automated machinery. The hex headless design with 3/32" drive allows for flush installation in tight spaces while maintaining high torque capability. Cup tip serrations create permanent locking action that prevents loosening under dynamic loads, making these fine thread set screws ideal for precision assemblies, shaft collars, and gear positioning where exact alignment and secure fastening are paramount.
