Key Features & Benefits at a Glance
- Exceptional corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
- Superior load-bearing capacity from 60,000 psi tensile strength, ensuring reliable performance under high-stress applications.
- Optimized for rapid installation with a No. 4 Phillips drive and coarse UNC threads, reducing assembly time and labor costs.
- Consistent, secure fastening guaranteed by Class 2A thread fit and full threading along the 6-inch length for maximum grip.
- Enhanced durability and wear resistance due to Rockwell B70 hardness, maintaining integrity through repeated use.
- Broad compatibility with standard UNC coarse-threaded components, simplifying inventory and replacement processes.
- Regulatory peace of mind through compliance with ASME B18.6.3, RoHS 3, and REACH, meeting strict industrial and environmental standards.
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these zinc-plated steel screws address critical challenges in construction, machinery assembly, and infrastructure projects. The rounded pan head design distributes clamping force evenly, reducing the risk of surface damage, while the Phillips drive ensures efficient torque transfer without slippage. With UNC coarse threads and full threading, they provide exceptional pull-out resistance in wood, metal, and composite materials, minimizing loosening from vibrations. The 60,000 psi tensile strength and corrosion-resistant plating make them ideal for outdoor or high-moisture environments, delivering long-term reliability and reducing maintenance costs for B2B buyers.
Specification Summary & Compliance
This screw features precise Class 2A thread fit and UNC coarse spacing per ASME B18.6.3 specifications, ensuring dimensional accuracy and interchangeability. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances. Manufactured to inch system standards, it includes a 6-inch length, 5/16"-18 thread size, and Rockwell B70 hardness for consistent quality in industrial fastening applications.
