S-92311A287 6-32 x 1 1/4" 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
• Maximum holding power through the cup point tip design that bites into mating surfaces for secure, permanent fastening
• Precise thread engagement with Class 3A fit ensuring tight tolerances and reliable performance in critical assemblies
• Easy installation in confined spaces using the headless hex drive design with 1/16" drive size
• Enhanced durability from Rockwell B80 hardness, providing excellent resistance to wear and deformation
• Wide compatibility with 6-32 UNC coarse threads and right-hand direction for standard industrial applications
• Regulatory compliance assurance meeting ASME B18.3 specifications and environmental standards including RoHS 3 and REACH

Professional Applications & Engineering Value

This 6-32 UNC set screw delivers exceptional engineering value in demanding industrial applications where vibration resistance and permanent positioning are critical. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery operating in humid or chemically aggressive environments, while the cup point tip creates deep indentations in shaft components to prevent rotational slippage under heavy loads. The headless hex drive design allows for flush mounting in space-constrained assemblies, making it ideal for precision equipment, automotive components, and manufacturing fixtures where Class 3A thread fit ensures consistent clamping force without loosening. These set screws maintain their mechanical integrity through repeated adjustment cycles thanks to the controlled Rockwell B80 hardness, offering reliable performance in high-stress applications.

Specification Summary & Compliance

This precision fastener features 6-32 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy and tight tolerances. The product strictly adheres to ASME B18.3 manufacturing specifications and demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors without hazardous substance restrictions.
