S-90128A231 10-24 x 2 1/4" ASTM A574 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 PSI ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
• Superior corrosion resistance from zinc plating extends service life in harsh industrial environments, minimizing maintenance needs.
• Precise Class 3A thread fit provides tighter tolerances for secure, vibration-resistant assemblies in critical machinery.
• High hardness rating (Rockwell C37) enhances wear resistance and durability under repetitive loading conditions.
• Standard hex socket drive allows for easy installation with common tools, improving assembly efficiency and reducing labor time.
• Coarse UNC threading enables faster installation and better grip in softer materials or where quick disassembly is required.
• Compliance with ASTM A574, RoHS 3, and REACH ensures material consistency, environmental safety, and global regulatory acceptance for B2B procurement.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, this 10-24 UNC Socket Head Cap Screw addresses common challenges like vibration loosening and material fatigue. The zinc-plated alloy steel construction provides a robust barrier against rust and chemical exposure, making it ideal for outdoor equipment, automotive assemblies, and heavy machinery. Its partially threaded design and coarse thread profile ensure rapid installation and reliable clamping force in applications requiring frequent adjustments or high shear strength. By combining 170,000 PSI tensile strength with a Class 3A thread fit, this fastener minimizes backlash in precision components, enhancing overall system integrity and reducing downtime in production lines.

Specification Summary & Compliance

This screw maintains precise Class 3A thread fit per UNC standards, with a thread size of 10-24 and minimum thread length of 3/4".
