Professional Applications & Engineering Value

These 0-80 UNF passivated stainless steel screws address critical challenges in precision engineering applications where corrosion resistance and thread reliability are paramount. The fine UNF threading with Class 2A fit provides superior vibration resistance in electronic enclosures, instrumentation, and aerospace components where loosening under dynamic loads poses significant failure risks. The passivated 18-8 stainless steel construction delivers exceptional protection against chemical exposure and atmospheric corrosion, making these rounded head screws ideal for medical devices, marine equipment, and food processing machinery. The combination of 70,000 psi tensile strength with controlled Rockwell B70 hardness ensures these fasteners maintain clamping force without thread stripping or head deformation, even in high-cycle assembly operations. The Phillips No. 0 drive design facilitates efficient installation in confined spaces while the fully threaded 3/4" length provides maximum engagement depth for critical structural connections.

Specification Summary & Compliance

Manufactured to exacting ASME B18.6.3 specifications with precision Class 2A thread fit for consistent fastening performance. The 0-80 UNF fine thread configuration ensures secure connections in demanding applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees these components meet international standards for hazardous substance restrictions. Right-hand threaded design with complete threading along the entire 3/4" length provides uniform load distribution and reliable mechanical fastening characteristics.
