S-92785A516 8-32 x 5/8" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior vibration resistance with Class 3A thread fit ensuring secure, long-term fastening in high-stress applications
• Excellent corrosion resistance provided by 18-8 stainless steel construction for reliable performance in harsh environments
• Enhanced holding power from the 90° cone point tip that digs into mating surfaces for maximum grip
• Optimized installation efficiency with hex headless design and 5/64" drive for easy access in confined spaces
• Exceptional durability maintained through Rockwell B80 hardness for repeated use without deformation
• Reliable thread engagement with UNC coarse threads providing quick assembly and reduced cross-threading risk
• Industry compliance assurance meeting ASME B18.3 standards for consistent quality and performance

Professional Applications & Engineering Value

These 8-32 UNC set screws deliver critical engineering solutions for industrial applications where vibration resistance and secure positioning are paramount. The 18-8 stainless steel composition provides excellent corrosion resistance, making these hex headless set screws ideal for machinery, automotive components, and electrical enclosures exposed to moisture or chemicals. The 90° cone point design creates positive mechanical locking by embedding into shaft surfaces, preventing axial movement even under extreme vibration. With Class 3A thread fit precision and coarse UNC threads, these set screws offer faster installation and superior holding power compared to standard fasteners. The headless configuration with 5/64" hex drive allows installation in tight spaces where conventional screw heads would interfere, while maintaining the high torque capability needed for industrial applications.

Specification Summary & Compliance
