S-90357A128 10-24 x 5/8" Alloy Steel Ultra-Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 140,000 psi provides reliable performance in high-stress applications
• Precision Class 3A thread fit ensures superior engagement and vibration resistance in critical assemblies
• Ultra-low socket head profile enables installation in confined spaces where clearance is limited
• Black-oxide coating on alloy steel offers corrosion resistance and enhanced durability in industrial environments
• Fully threaded design maximizes grip length and holding power across the entire fastener length
• Rockwell C32 hardness maintains thread integrity and prevents stripping during repeated installations
• Coarse UNC threads provide faster installation and reduced cross-threading risk in production environments

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these black-oxide alloy steel socket head cap screws deliver exceptional performance where space constraints and vibration resistance are critical concerns. The ultra-low profile head design combined with 10-24 UNC coarse threads allows for reliable fastening in compact machinery, automotive assemblies, and precision equipment. The Class 3A thread fit ensures minimal play and superior clamping force, effectively preventing loosening under dynamic loads. The fully threaded configuration provides consistent engagement throughout the entire length, making these screws ideal for applications requiring maximum holding power in thin materials or stacked components. With their 140,000 psi tensile strength and Rockwell C32 hardness, these fasteners maintain integrity in high-stress environments while the black-oxide surface treatment resists corrosion in challenging operating conditions.

Specification Summary & Compliance

These socket head cap screws feature precision 10-24 UNC coarse threads with Class 3A fit tolerance, ensuring exacting dimensional accuracy per inch system standards. The manufacturing process maintains tight length tolerance of -0.005" to 0.005" for consistent performance. All components are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for global industrial applications requiring strict chemical substance control.
