Professional Applications & Engineering Value

This 10-24 4" flat head screw delivers critical engineering solutions where corrosion resistance and structural integrity are paramount. The passivated 18-8 stainless steel construction provides exceptional protection against oxidation and chemical exposure, making these oval head Phillips screws ideal for marine equipment, food processing machinery, and outdoor industrial applications. The UNC coarse threading ensures rapid installation and superior holding power in various materials, while the partially threaded design allows for precise clamping force distribution. With 80,000 psi tensile strength, these screws maintain joint integrity under significant vibrational loads and stress conditions, addressing common failure points in heavy machinery and structural assemblies.

Specification Summary & Compliance

Manufactured to exacting ASME B18.6.3 specifications with Class 2A thread fit tolerance for consistent performance. Features UNC coarse threads (10-24) with right-hand direction and partial threading up to 1½" minimum thread length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. The oval head profile with standard dimensions (0.362" head diameter, 0.176" head height) and 82° countersink angle provides optimal flush mounting capabilities.
