S-92311A315 2-56 x 3/4" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments
• Exceptional vibration resistance due to the cup point tip design that bites securely into mating surfaces
• Precise thread engagement with Class 3A fit ensuring reliable fastening in critical applications
• Easy installation in confined spaces thanks to the hex headless design requiring minimal clearance
• Optimized for high-strength applications with Rockwell B80 hardness providing excellent mechanical properties
• Reliable coarse threading using 2-56 UNC specification for quick assembly and disassembly
• Comprehensive regulatory compliance meeting ASME B18.3, RoHS 3, and REACH standards for global industrial use

Professional Applications & Engineering Value

This 2-56 UNC set screw delivers exceptional engineering value in precision assembly applications where space constraints and vibration resistance are critical concerns. The 18-8 stainless steel composition provides excellent corrosion resistance for demanding environments, while the hex headless design allows installation in tight spaces where conventional fasteners cannot operate. The cup point tip creates permanent deformation in the mating surface, ensuring superior grip that prevents loosening under continuous vibration - a common failure point in industrial machinery, automotive components, and precision equipment. The Class 3A thread fit guarantees precise engagement with mating parts, making these set screws ideal for alignment-critical applications where positional accuracy is paramount.

Specification Summary & Compliance

This precision fastener features a 2-56 UNC coarse thread with Class 3A fit for superior dimensional accuracy and thread engagement. Manufacturing complies with ASME B18.3 specifications for set screws, ensuring consistent quality and performance. The product meets RoHS 3 (2015/863/EU) compliance for restricted hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, making it suitable for global industrial applications requiring environmental compliance.
