S-90665A142 10-32 x 1" 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 demanding applications.
• Superior corrosion resistance from zinc plating protects against rust and environmental degradation, extending service life in harsh industrial settings.
• Precise Class 3A thread fit guarantees tight, secure connections with minimal play, enhancing assembly accuracy and vibration resistance.
• Low-profile socket head design allows for installation in confined spaces while providing ample torque transfer with a 3/32" hex drive.
• High hardness rating (Rockwell C39) maintains thread integrity and drive socket shape, preventing stripping during repeated use.
• Full thread coverage along the 1" length ensures consistent clamping force and flexibility in various material thicknesses.
• Compliance with ASTM A574, RoHS 3, and REACH assures material quality and environmental safety for global supply chain integration.

Professional Applications & Engineering Value

Engineered for precision and durability, these 10-32 UNF low socket head cap screws address critical needs in machinery, automotive, and electronics assembly where space constraints and vibration are concerns. The zinc-plated alloy steel construction combats corrosion in humid or chemically exposed environments, while the fine thread and Class 3A fit provide superior resistance to loosening under dynamic loads. The low-profile head and hex drive facilitate easy installation with standard tools, reducing assembly time and improving maintenance accessibility in compact designs. Ideal for securing components in engines, control systems, and structural frames, these screws deliver reliable fastening that meets rigorous industrial standards.
