Professional Applications & Engineering Value
This 18-8 stainless steel hex headless set screw delivers critical engineering advantages in demanding applications where vibration resistance and corrosion protection are paramount. The UNF fine thread design significantly reduces loosening under dynamic loads, making it ideal for precision machinery, automotive components, and industrial equipment. The cup tip provides concentrated clamping force on shafts and collars, while the headless configuration allows seamless integration where protruding fasteners are impractical. Manufactured to ASME B18.3 specifications with Class 3A thread fit, it ensures reliable performance in critical assemblies requiring repeatable accuracy and long-term reliability.
Specification Summary & Compliance
This set screw maintains Class 3A thread fit per UNF standards with precise 5/16"-24 fine threading and 2" length. It conforms to ASME B18.3 manufacturing specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The Rockwell B80 hardness and 18-8 stainless steel material ensure consistent mechanical performance and corrosion resistance in industrial fastening applications.
