Key Features & Benefits at a Glance
- Exceptional corrosion resistance with zinc plating, extending service life in demanding industrial environments
- Superior tensile strength of 60,000 PSI ensures reliable performance under heavy loads and vibration
- Rockwell B70 hardness provides excellent wear resistance and prevents thread deformation during installation
- Class 2A thread fit with UNC coarse threading enables faster assembly and reduced cross-threading risks
- Full threading along the 4 1/4" length delivers maximum grip and holding power across the entire fastener
- Phillips No. 2 drive with rounded pan head combines secure torque transmission with a low-profile, finished appearance
- Comprehensive compliance with ASME B18.6.3, RoHS 3, and REACH ensures material safety and manufacturing consistency
Professional Applications & Engineering Value
These 10-24 UNC zinc-plated steel screws address critical industrial fastening challenges where vibration resistance and long-term reliability are paramount. The coarse thread design excels in soft materials and high-vibration applications, maintaining secure connections where fine threads might loosen. The zinc-plated steel construction provides essential corrosion protection for machinery, equipment assemblies, and outdoor applications, while the fully threaded design ensures uniform stress distribution across the entire 4 1/4" length. The combination of 60,000 PSI tensile strength and Rockwell B70 hardness makes these rounded head Phillips screws ideal for structural applications, automotive assemblies, and heavy equipment where fastener failure is not an option.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with UNC coarse threading (10-24 size) and compliant with ASME B18.6.3 manufacturing standards. These zinc-plated steel screws meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements, ensuring they contain no restricted substances and are safe for various industrial applications.
