Professional Applications & Engineering Value

These 10-24 UNC flat head Phillips screws deliver critical engineering solutions where flush surface mounting and high tensile strength are paramount. The zinc-plated steel construction resists corrosion in industrial settings, while the coarse UNC threads provide rapid installation and secure holding power in metal, plastic, and wood assemblies. The 100° countersink angle ensures a clean, recessed fit that eliminates protrusions in machinery, electronics enclosures, and automotive components. With full threading and Class 2A fit, these screws maintain consistent clamping force, reducing the risk of loosening under dynamic loads. Ideal for OEM manufacturing, maintenance repairs, and structural applications requiring ASME B18.6.3 compliance and environmental regulation adherence.

Specification Summary & Compliance

Manufactured to precise Class 2A thread fit tolerances with UNC coarse threads (10-24 size) and right-hand threading. The screws meet ASME B18.6.3 specifications for dimensional accuracy and performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they are free from hazardous substances. Additional specifications include Rockwell B70 hardness, 0.362" head diameter, and standard flat head profile for consistent industrial application.
