S-92311A317 2-64 x 1/8" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance from 18-8 Stainless Steel construction, ensuring long-term reliability in harsh environments
• Precise thread engagement with Class 3A thread fit for secure fastening and vibration resistance in critical assemblies
• High-strength performance backed by Rockwell B80 hardness, maintaining structural integrity under mechanical stress
• Space-saving headless design with hex drive for flush mounting in confined spaces and tool accessibility
• Enhanced grip capability with cup tip design that digs into shaft surfaces to prevent component slippage
• Industry-standard compliance with ASME B18.3 specifications for guaranteed dimensional accuracy and interchangeability
• Environmental responsibility through RoHS 3 and REACH compliance, meeting global regulatory requirements

Professional Applications & Engineering Value

This 2-64 UNF set screw delivers exceptional engineering value in precision assemblies where space constraints and corrosion resistance are critical. The 18-8 Stainless Steel material provides excellent protection against oxidation and chemical exposure, while the Class 3A thread fit with fine thread spacing ensures superior clamping force distribution and vibration resistance in dynamic applications. The headless hex drive design allows for completely flush installations in machinery, automotive components, and electronic enclosures where protruding fasteners are unacceptable. The cup tip configuration creates positive engagement with shaft surfaces, preventing relative movement in precision positioning applications. These set screws are particularly valuable in aerospace, medical device manufacturing, and precision instrumentation where reliability and dimensional accuracy are non-negotiable requirements.

Specification Summary & Compliance

This precision fastener features Class 3A thread fit tolerance for superior engagement, manufactured to UNF fine thread standards with 2-64 thread size and 0.086" thread diameter. The 1/8" length and 0.035" hex drive provide consistent dimensional accuracy per ASME B18.3 specifications. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures responsible material sourcing and manufacturing practices for global industrial applications.
