Professional Applications & Engineering Value

Engineered for demanding industrial applications, these 1/2"-13 UNC flat head screws provide critical solutions for machinery assembly, structural frameworks, and equipment manufacturing. The 18-8 stainless steel construction combined with passivated finish delivers exceptional resistance to corrosion and chemical exposure, significantly extending service life in challenging environments. The Class 3A thread fit and coarse UNC threading ensure rapid assembly with minimal cross-threading risk, while the 82° countersink angle creates flush surfaces that prevent snagging and improve aerodynamic profiles. The hex drive design allows for high-torque installation in confined spaces, making these fully threaded screws ideal for applications requiring maximum clamping force and vibration resistance across industrial machinery, transportation equipment, and structural assemblies.

Specification Summary & Compliance

These flat head screws maintain precision Class 3A thread fit with UNC coarse threading (1/2"-13) and feature complete compliance with ASME B18.3 manufacturing standards. The dimensional specifications include 1" length, 0.5" thread diameter, and standard flat head profile with 82° countersink angle. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) requirements, ensuring environmental safety and material transparency for global industrial applications.
