Professional Applications & Engineering Value
Engineered for demanding industrial environments, these 316 stainless steel flat head screws deliver exceptional performance where corrosion resistance is critical. The combination of 70,000 psi tensile strength and Rockwell B55 hardness ensures reliable fastening in structural applications, marine equipment, chemical processing systems, and food processing machinery. The UNC coarse thread spacing provides superior pull-out resistance in softer materials while the fully threaded design maximizes engagement depth. The passivated finish enhances the natural corrosion resistance of 316 stainless steel, making these flat head screws ideal for applications exposed to moisture, chemicals, and extreme temperatures. The 82° countersink angle ensures proper seating in standardized chamfered holes, creating clean, flush surfaces that minimize protrusion in precision assemblies.
Specification Summary & Compliance
Manufactured to exacting ASME B18.3 specifications with precision Class 3A thread fit for superior dimensional accuracy. Features 7/16"-14 UNC coarse threads with right-hand orientation and 1" length in inch system measurements. The flat head design incorporates standard profile with 82° countersink angle and hex drive compatibility for secure installation. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
