S-90128A164 6-32 x 1 1/2" ASTM A574 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 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 provides tighter tolerances for secure, vibration-resistant assemblies, minimizing loosening in machinery and equipment.
• Hex socket drive design allows for high-torque installation with standard 7/64" hex keys, enabling efficient assembly and disassembly in confined spaces.
• Partially threaded shank offers optimal grip and alignment in materials, preventing cross-threading and ensuring consistent clamping force.
• Coarse UNC threading facilitates quick installation and removal, saving time in maintenance and production cycles.
• Compliance with ASTM A574 and environmental standards guarantees consistent quality and safe use across global industrial markets.

Professional Applications & Engineering Value

These 6-32 UNC socket head cap screws are engineered to address critical fastening challenges in industrial environments where vibration, high loads, and corrosion are common. The zinc-plated alloy steel construction provides a durable barrier against moisture and chemicals, ideal for machinery, automotive assemblies, and electronic enclosures. With a Rockwell C37 hardness and 170,000 PSI tensile strength, they resist deformation under stress, ensuring long-term joint integrity. The partially threaded design and Class 3A fit enhance alignment and reduce the risk of strip-out in repetitive disassembly scenarios, making them a reliable choice for maintenance-heavy applications. Their coarse thread and hex drive enable rapid installation, boosting efficiency in production lines while meeting stringent ASTM A574 specifications.
