Professional Applications & Engineering Value
These 0-80 UNF flat head screws deliver critical performance advantages in precision engineering applications where space constraints and material compatibility are paramount. The passivated 18-8 stainless steel construction provides essential corrosion protection for electronics, aerospace components, and medical devices exposed to moisture or chemicals. The UNF fine thread configuration offers superior holding power in thin-section materials and delicate assemblies, while the Phillips drive ensures controlled installation torque. The combination of 80,000 psi tensile strength and Rockwell B80 hardness makes these fully threaded screws ideal for vibration-resistant applications where fastener integrity cannot be compromised. The standardized 82° countersink angle enables perfect flush mounting in precision machinery and instrumentation panels.
Specification Summary & Compliance
Manufactured to exacting ASME B18.6.3 specifications with Class 2A thread fit tolerances for consistent dimensional accuracy. These right hand thread screws feature UNF fine thread spacing (0-80) and are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The passivated 18-8 stainless steel construction meets industrial standards for corrosion resistance and mechanical properties, ensuring reliable performance across various applications.
