• Enhanced surface protection through passivated finish, extending service life and maintaining appearance
• Precision threading with Class 2A fit and UNC coarse thread profile ensuring secure, vibration-resistant connections
• Full threading design provides maximum grip length and uniform load distribution across the entire fastener
• Standard flat head profile with 82° countersink angle for flush mounting and clean aesthetic finish
• Comprehensive compliance with ASME B18.6.3 manufacturing standards and environmental regulations including RoHS 3 and REACH

Professional Applications & Engineering Value

These 316 stainless steel flat head screws deliver critical corrosion resistance where other fasteners fail, making them essential for marine equipment, chemical processing, and food-grade applications. The passivated finish creates an additional protective oxide layer that significantly enhances pitting resistance in chloride-rich environments. With fully threaded UNC coarse threading and Class 2A fit, these screws provide excellent engagement in both metals and plastics, reducing the risk of cross-threading during assembly. The slotted drive style offers compatibility with standard tools while the flat head design ensures seamless integration where flush surfaces are required. Engineered to withstand constant exposure to moisture, chemicals, and temperature variations, these fasteners maintain their 70,000 psi tensile strength and structural integrity in the most demanding industrial settings.

Specification Summary & Compliance

This 10-24 UNC flat head screw features precision Class 2A thread fit with coarse thread spacing for optimal engagement. Manufacturing strictly follows ASME B18.6.3 specifications ensuring dimensional accuracy and performance reliability. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances. With complete threading along the 1/2" length and standardized 82° countersink angle, these screws deliver consistent performance across industrial applications requiring corrosion-resistant fastening solutions.
