S-90357A125 8-32 x 7/16" Alloy Steel Ultra-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 demanding applications.
• Superior corrosion resistance from the black-oxide finish on alloy steel extends service life and maintains integrity in harsh industrial environments.
• Precision Class 3A thread fit guarantees tight tolerances and secure fastening, minimizing loosening and vibration-related issues.
• Ultra-low socket head profile allows installation in confined spaces where standard head heights are impractical, enhancing design flexibility.
• Coarse 8-32 UNC threads enable quicker assembly and disassembly, saving time in maintenance and production workflows.
• Strict length tolerance of ±0.005" ensures consistent sizing for precise alignment and reduced assembly errors in automated systems.
• Full compliance with RoHS 3 and REACH regulations assures environmental safety and meets global standards for industrial components.

Professional Applications & Engineering Value

Engineered for high-performance industrial settings, these socket head cap screws with black-oxide alloy steel construction address common challenges like space constraints and corrosion. The ultra-low profile head and 5/64" hex drive facilitate secure fastening in compact assemblies, such as machinery, automotive systems, and electronic enclosures, where standard screws may protrude or fail. The 8-32 UNC coarse threads with Class 3A fit provide excellent grip and resistance to vibration, reducing maintenance needs in dynamic environments. Combined with a Rockwell C32 hardness, these screws deliver durability and reliability, making them ideal for applications requiring repeated adjustments or exposure to oils and moisture.
