S-92220A163 10-24 x 1/2" ASTM A574 Alloy Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 140,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in critical applications.
• Superior corrosion resistance from the black-oxide finish on alloy steel extends service life in demanding industrial environments.
• Precise Class 3A thread fit provides tighter tolerances for secure, vibration-resistant assemblies, minimizing loosening over time.
• Low-profile socket head design with 3/32" hex drive allows for installation in confined spaces while maintaining high torque capability.
• Coarse UNC threading enables faster installation and reduced cross-threading risks compared to fine-thread alternatives.
• Full-threaded construction ensures consistent engagement along the entire 1/2" length for uniform load distribution.
• Rockwell C39 hardness rating delivers optimal balance between strength and ductility for durable, reusable fastening solutions.

Professional Applications & Engineering Value

Engineered for precision assemblies requiring high-strength fastening, these black-oxide alloy steel socket head cap screws solve common industrial challenges where space constraints meet demanding mechanical requirements.
