Key Features & Benefits at a Glance
- Superior corrosion resistance with passivated 18-8 stainless steel construction for extended service life in harsh environments
- Exceptional tensile strength rated at 80,000 psi ensures reliable fastening under high-stress conditions
- Precision Class 2A thread fit provides consistent engagement and reduces cross-threading risks during installation
- Optimized 82° countersink angle with undercut flat head design creates flush mounting and improved load distribution
- Full threading coverage maximizes grip length and enhances pull-out resistance across the entire fastener
- Rockwell B80 hardness rating maintains structural integrity while providing necessary ductility
- Comprehensive compliance with ASME B18.6.3, RoHS 3, and REACH ensures regulatory acceptance and material safety
Professional Applications & Engineering Value
These 10-24 UNC flat head screws deliver critical performance advantages for industrial applications where corrosion resistance and reliable fastening are paramount. The passivated 18-8 stainless steel construction provides exceptional protection against oxidation and chemical exposure, making these flat head Phillips screws ideal for marine equipment, food processing machinery, and outdoor infrastructure. The combination of coarse UNC threading with Class 2A fit ensures rapid installation and vibration resistance, while the undercut flat head profile with 82° countersink angle prevents surface protrusion in precision assemblies. With 80,000 psi tensile strength and full threading, these fasteners maintain joint integrity in high-vibration environments where loosening could compromise safety and operational efficiency.
Specification Summary & Compliance
Manufactured to exacting dimensional standards with Class 2A thread fit and UNC coarse thread profile (10-24). These 5/16" length screws feature precise 82° countersink angles and undercut head design per ASME B18.6.3 specifications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and material safety for global industrial applications.
