S-92220A152 8-32 x 3/8" 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 harsh or humid environments, minimizing maintenance needs.
• Precise Class 3A thread fit provides tighter tolerances for secure, vibration-resistant connections in machinery and assemblies.
• Low-profile socket head design allows for installation in confined spaces while maintaining a sleek, unobtrusive appearance.
• High hardness (Rockwell C39) enhances wear resistance, ensuring the screw retains its integrity through repeated use and disassembly.
• Coarse UNC threading facilitates quicker installation and reduces cross-threading risks, improving assembly efficiency.
• Full threading along the length offers consistent grip and adjustable positioning for versatile fastening solutions.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these 8-32 UNC thread socket head cap screws address common challenges like space constraints and vibration-induced loosening. The low-profile head and 5/64" hex drive enable secure fastening in compact assemblies, such as electronic enclosures, precision instruments, and automated machinery, where standard screws may not fit. Made from black-oxide alloy steel, they resist corrosion and wear, ensuring longevity in environments exposed to moisture or chemicals. The Class 3A thread fit and coarse spacing provide a tight, reliable hold that withstands dynamic loads, reducing downtime and maintenance costs. Ideal for OEM and MRO applications, these screws deliver consistent performance in aerospace, automotive, and manufacturing sectors.
