S-92505A622 3/8"-16 x 3/4" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 3A thread fit for precise, vibration-resistant fastening in demanding applications
• Enhanced corrosion resistance through black oxide coating on alloy steel, extending service life in industrial environments
• Optimal torque transmission via 3/16" hex drive design, preventing cam-out and ensuring secure installation
• Extended tip design creates deeper engagement and improved grip on shafts and components
• Exceptional durability with Rockwell C45 hardness, maintaining structural integrity under heavy loads
• Reliable coarse threading (UNC) for quicker assembly and reduced cross-threading risks
• Headless construction allows for flush mounting in space-constrained applications

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 combined with Rockwell C45 hardness provides exceptional resistance to wear and environmental factors, making it ideal for permanent fastening applications in machinery, automotive components, and power transmission systems. The extended tip design ensures maximum contact surface area, preventing slippage in high-torque applications while the hex drive configuration guarantees efficient installation without tool slippage. These headless set screws are particularly valuable in precision equipment where space optimization and reliable shaft positioning are paramount, offering engineers a compliant, high-performance fastening solution that withstands vibration and heavy operational stresses.

Specification Summary & Compliance

Manufactured to exacting standards with Class 3A thread fit precision and UNC coarse threading (3/8"-16) for optimal performance. The extended tip features precise dimensional tolerances (tip diameter: 0.25" with -0.009" to 0 tolerance; tip length: 0.099" with -0.005" to 0 tolerance). This set screw complies with ASME B18.3 specifications and meets critical regulatory requirements including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental responsibility and industrial safety standards.
