S-95289A124 10-24 x 5/16" 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 holding power achieved through Class 3A thread fit precision and extended tip design for maximum grip and vibration resistance
• Optimized installation efficiency with 3/32" hex drive that prevents cam-out and ensures secure tool engagement during tightening
• Enhanced durability backed by Rockwell B80 hardness rating for reliable performance under mechanical stress
• Versatile coarse threading (UNC) enables quick assembly and disassembly while maintaining secure fastening in various materials
• Space-saving headless design allows for flush mounting in applications where protruding fastener heads are not feasible
• Regulatory compliance assurance with RoHS 3 and REACH environmental standards for global market acceptance

Professional Applications & Engineering Value

This 10-24 UNC set screw delivers critical engineering solutions for industrial applications requiring precise component positioning and permanent fastening. The 18-8 stainless steel composition provides excellent resistance to oxidation and chemical corrosion, making it ideal for machinery, automotive assemblies, and electronic enclosures operating in demanding environments. The extended tip design (0.098" length) creates deeper penetration into mating materials, significantly reducing loosening from vibration – a common failure point in rotating equipment and precision instruments. The Class 3A thread fit ensures tight tolerances for secure engagement, while the headless configuration enables seamless integration in space-constrained assemblies. These set screws are particularly valuable in pulley systems, gear assemblies, and coupling applications where reliable positioning is paramount.

Specification Summary & Compliance

This precision-engineered fastener maintains Class 3A thread fit tolerances per UNC standards with a thread size of 10-24 and coarse thread spacing. Manufacturing conforms to ASME B18.3 specifications for dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial markets. Critical dimensions include a 5/16" length with extended tip specifications maintained within tight tolerances (-0.005" to 0" for tip length, -0.007" to 0" for tip diameter) for consistent performance across production runs.
