S-90289A237 10-24 x 3/16" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-oxide coating for reliable performance in demanding industrial environments
• Superior locking security through serrated design that prevents unwanted loosening under vibration and dynamic loads
• Precise Class 3A thread fit ensures tight tolerances and consistent engagement for maximum holding power
• High-strength alloy steel construction with Rockwell C45 hardness provides exceptional durability and wear resistance
• Space-saving headless design with 3/32" hex drive allows installation in confined spaces while maintaining tool accessibility
• Optimized cup tip configuration creates concentrated contact pressure for secure positioning of components on shafts and axles
• Full regulatory compliance with ASME B18.3, RoHS 3, and REACH standards guarantees safety and environmental responsibility

Professional Applications & Engineering Value

This 10-24 UNC set screw delivers exceptional engineering value in precision assembly applications where space constraints and vibration resistance are critical concerns. The black-oxide alloy steel construction combined with Rockwell C45 hardness ensures the fastener maintains its integrity under continuous mechanical stress, while the serrated locking mechanism effectively counters rotational forces in pulley systems, gear assemblies, and coupling applications. The coarse UNC thread pattern facilitates quick installation and provides superior holding strength in softer materials, making it ideal for manufacturing equipment, automotive components, and industrial machinery where reliable set screw performance is non-negotiable. The headless hex drive design with 3/32" drive size enables flush mounting while maintaining accessibility for standard hex keys.
