Professional Applications & Engineering Value
These 8-32 UNC flat head Phillips screws in 316 stainless steel deliver exceptional performance in demanding industrial settings where corrosion resistance is critical. The combination of fully threaded coarse UNC threads and Class 2A thread fit ensures secure fastening in various materials while the passivated finish provides an additional protective layer against chemical attack and oxidation. Engineered with a standard 82° countersink angle, these screws sit flush with surfaces, making them ideal for applications requiring smooth finishes in marine equipment, chemical processing machinery, food processing systems, and architectural metalwork. The Phillips drive style offers efficient installation with standard tools, while the 1-1/4" length provides versatile fastening capabilities across multiple material thicknesses.
Specification Summary & Compliance
These flat head screws feature Class 2A thread fit with UNC coarse threading (8-32 size) and comply with ASME B18.6.3 manufacturing specifications. The dimensional accuracy includes a head diameter of 0.312" and length of 1-1/4". Environmental compliance is confirmed through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications, ensuring restricted substance compliance for industrial applications worldwide.
