S-92311A286 6-32 x 1 1/8" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Exceptional holding power from the cup point design that bites into surfaces for secure, vibration-resistant fastening
• Precise thread engagement with Class 3A fit ensuring tight tolerances and reliable performance in critical assemblies
• High durability backed by Rockwell B80 hardness for excellent wear resistance and long service life
• Easy installation in confined spaces using the 1/16" hex drive on the headless design
• Wide compatibility with UNC coarse threads (6-32) for quick assembly and disassembly in various applications
• Regulatory compliance meeting ASME B18.3 standards and environmental regulations (RoHS 3, REACH) for safe global use

Professional Applications & Engineering Value

This 6-32 UNC set screw delivers exceptional engineering value in demanding industrial applications where reliability is paramount. The 18-8 stainless steel material provides excellent corrosion resistance, making it suitable for machinery exposed to moisture, chemicals, or outdoor elements. The cup point design creates concentrated pressure that digs into shaft surfaces, preventing rotational slippage in pulleys, gears, and collars - solving common vibration-induced loosening problems. The headless configuration with hex drive allows installation in tight spaces where conventional screw heads would interfere, while the coarse UNC threads enable rapid assembly in production environments. These features combine to create a precision set screw solution that maintains clamping force under dynamic loads, reducing maintenance needs and improving equipment uptime in manufacturing, automotive, and heavy machinery applications.
