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.
- Zinc-plated alloy steel construction provides excellent corrosion resistance, extending service life in harsh industrial environments.
- Class 3A thread fit offers superior precision and tighter tolerances for secure, vibration-resistant assemblies.
- Hex socket drive design allows for high torque application and easy installation in confined spaces with standard tools.
- Coarse UNC threading enables faster installation and better performance in materials where fine threads are not suitable.
- Full threading along the entire length provides maximum grip and adjustment flexibility in various assembly scenarios.
- Compliance with ASTM A574, RoHS 3, and REACH standards guarantees material quality and environmental safety for global industrial use.
Professional Applications & Engineering Value
This 10-24 UNC Socket Head Cap Screw delivers critical engineering value where space constraints and high strength requirements intersect. The zinc-plated alloy steel material, combined with Rockwell C37 hardness, provides exceptional resistance to wear and environmental degradation, making it ideal for machinery, automotive assemblies, and heavy equipment. The hex drive and socket head design enable secure fastening in recessed or hard-to-reach areas, while the coarse thread spacing ensures quick installation and reliable holding power in softer materials or where vibration is a concern. These features collectively address common industrial challenges such as fastener loosening, corrosion-induced failure, and installation inefficiency.
Specification Summary & Compliance
This socket head cap screw features precise Class 3A thread fit per UNC standards, ensuring tight tolerances and reliable engagement. Manufacturing adheres to ASTM A574 specifications for high-strength alloy steel fasteners. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for use in regulated industries and international markets.
