S-90357A155 7/16"-14 x 1" 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.
• Precision Class 3A thread fit provides superior engagement and vibration resistance, minimizing loosening in critical assemblies.
• Black-oxide coating on alloy steel offers enhanced corrosion resistance and durability, extending service life in harsh industrial environments.
• Ultra-low socket head profile allows installation in confined spaces where standard head height is prohibitive, increasing design flexibility.
• Rockwell C32 hardness delivers excellent wear resistance and maintains thread integrity through repeated installation cycles.
• Coarse UNC threading enables faster assembly and disassembly while providing strong holding power in various materials.
• Tight length tolerance (±0.005") ensures consistent performance and proper fit in precision applications requiring exact dimensional control.

Professional Applications & Engineering Value

These 7/16"-14 UNC socket head cap screws with black-oxide alloy steel construction address critical engineering challenges in industrial applications. The ultra-low profile head design solves space constraints in compact machinery, jigs, and fixtures where standard fasteners cannot fit. The coarse thread configuration provides excellent grip in soft materials and enables rapid assembly in high-volume production environments. With 140,000 psi tensile strength and Rockwell C32 hardness, these fasteners withstand extreme mechanical loads in heavy equipment, automotive systems, and industrial machinery. The fully threaded right-hand design ensures maximum holding power along the entire fastener length, while the 1/4" hex drive accommodates standard tools for efficient installation and maintenance operations.
