S-95235A503 8-32 x 5/16" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior vibration resistance through nylon patch thread locking technology that maintains integrity up to 250°F
• Exceptional holding power with Class 3A thread fit ensuring precise engagement and minimal backlash
• Optimized torque transmission via 5/64" hex drive design preventing tool slippage during installation
• Enhanced material durability with alloy steel construction hardened to Rockwell C45 for long-term reliability
• Secure fastening in deep applications thanks to extended tip design reaching further into mating components
• Industry-standard compatibility with UNC coarse threads meeting ASME B18.3 specifications
• Environmental compliance assurance with RoHS 3 and REACH regulations for global manufacturing applications

Professional Applications & Engineering Value

This 8-32 UNC set screw delivers critical engineering solutions for industrial assemblies requiring permanent positioning under dynamic loads. The alloy steel construction with Rockwell C45 hardness provides exceptional shear strength, while the nylon patch locking technology effectively counters vibration-induced loosening in machinery, automotive, and precision equipment applications. The extended tip design ensures deeper engagement in blind holes, and the Class 3A thread fit guarantees precise alignment in high-tolerance assemblies. These headless set screws with coarse thread spacing are engineered for rapid installation and reliable performance in demanding environments where maintenance access is limited.
