Professional Applications & Engineering Value
Engineered for demanding industrial fastening applications, these 10-24 UNC flat head screws deliver critical performance advantages where corrosion resistance and mechanical integrity are paramount. The passivated 18-8 stainless steel construction provides exceptional protection against chemical exposure and environmental degradation, while the UNC coarse threading with Class 2A fit ensures rapid installation and reliable thread engagement in various substrates. The 100° countersink angle and flat head profile enable flush mounting in precision assemblies, eliminating protrusion issues in machinery, electronics, and structural components. With 80,000 psi tensile strength and Rockwell B80 hardness, these fully threaded screws maintain clamping force under dynamic loads, making them ideal for vibration-prone environments where Phillips drive accessibility is required.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance and UNC coarse thread profile. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features 5/8" length with fully threaded design, right-hand thread direction, and standard flat head profile with 100° countersink angle.
