S-90044A519 10-24 x 2 3/4" ASME B18.3, ASTM A574 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress applications and prevents fastener failure
• Superior corrosion resistance from the Black-Oxide finish on Alloy Steel extends service life in demanding industrial environments
• Precision Class 3A thread fit guarantees secure, vibration-resistant connections with minimal risk of loosening
• High hardness rating (Rockwell C37) provides excellent wear resistance and maintains thread integrity through repeated use
• Full threading along the 2 3/4" length offers maximum adjustment flexibility and uniform clamping force distribution
• Standard hex socket drive (5/32") allows for high-torque installation in confined spaces with common tools
• 10-24 UNRC coarse thread enables faster assembly and reduced cross-threading risk compared to fine-pitch alternatives

Professional Applications & Engineering Value

These Black-Oxide Alloy Steel Socket Head Cap Screws deliver critical performance advantages in heavy machinery, automotive assemblies, and precision equipment where vibration resistance and structural integrity are paramount. The combination of 170,000 psi tensile strength and Rockwell C37 hardness addresses common failure points in dynamic load applications, while the Class 3A thread fit maintains precise alignment in high-precision assemblies. The corrosion-resistant Black-Oxide surface treatment provides essential protection in environments exposed to moisture, chemicals, and temperature variations, significantly extending maintenance intervals. Engineered with 10-24 UNRC coarse threads, these screws offer superior engagement in both metallic and composite materials, making them ideal for production lines requiring efficient, reliable fastening solutions.
