Professional Applications & Engineering Value
These 0-80 UNF flat head screws deliver critical engineering solutions where space constraints and corrosion resistance are paramount. The passivated 18-8 stainless steel construction provides exceptional protection against oxidation and chemical exposure, making them ideal for electronic enclosures, precision instruments, and aerospace components. The fine UNF threading ensures superior holding power in thin materials, while the 82° countersink angle creates seamless surface transitions. With full threading along the 11/32" length, these Phillips drive screws offer maximum engagement depth for vibration-resistant assemblies in industrial machinery and automotive systems where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance for precision assembly. The UNF fine thread (0-80) with right-hand direction ensures industry-standard compatibility. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming suitability for global industrial applications. All dimensional characteristics including 0.112" head diameter and 11/32" length maintain strict adherence to published engineering standards.
