S-92505A628 3/8"-16 x 1 1/2" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with Class 3A thread fit ensuring precise, vibration-resistant connections in demanding applications
• Superior corrosion resistance and wear durability thanks to Black Oxide surface treatment on high-strength alloy steel
• Extended tip design provides deeper penetration and enhanced grip on shafts and collars for secure component positioning
• High hardness rating (Rockwell C45) delivers excellent resistance to deformation under heavy loads and repeated use
• Coarse UNC threads enable faster installation and higher resistance to loosening in high-vibration environments
• Headless construction with hex drive allows for flush mounting and easy installation in confined spaces using standard tools
• Full regulatory compliance including RoHS 3 and REACH ensures environmental safety and global market acceptance

Professional Applications & Engineering Value

This 3/8"-16 UNC set screw delivers critical engineering solutions for industrial assembly challenges. The black oxide alloy steel construction provides superior corrosion resistance while maintaining the Rockwell C45 hardness needed for high-stress applications. The extended tip design ensures maximum contact surface area, preventing slippage in pulley systems, gear hubs, and coupling applications. The Class 3A thread fit guarantees precise engagement with mating components, eliminating play in precision machinery. As a headless set screw with hex drive, it offers space-saving installation where protruding fasteners are impractical, making it ideal for rotating assemblies, motor shafts, and precision equipment where reliable positioning is paramount.

Specification Summary & Compliance

This set screw features 3/8"-16 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy. Manufactured to ASME B18.3 specifications with precise tolerances including tip diameter (0.25" with -0.009" to 0 tolerance) and tip length (0.099" with -0.005" to 0 tolerance). The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
