Professional Applications & Engineering Value
This zinc-plated steel fillister head screw delivers exceptional performance in industrial settings where corrosion resistance and mechanical strength are critical. The 12-24 UNC coarse thread design provides rapid assembly and superior holding power in materials prone to stripping, while the slotted drive offers compatibility with standard tools for maintenance and production lines. Engineered with 60,000 psi tensile strength and Rockwell B69 hardness, it withstands high-stress applications in machinery, electrical enclosures, and automotive assemblies. The rounded fillister head combines a low-profile aesthetic with enhanced bearing surface, distributing clamp load effectively without sinking into softer materials. Fully compliant with ASME B18.6.3 specifications, this screw ensures interchangeability and reliability in precision-driven environments.
Specification Summary & Compliance
This screw features Class 2A thread fit per UNC standards with a diameter of 0.216" and coarse thread spacing, ensuring dimensional accuracy for consistent performance. Manufacturing and material specifications strictly adhere to ASME B18.6.3 for mechanical and dimensional requirements. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances and supporting sustainable procurement practices in industrial supply chains.
