Key Features & Benefits at a Glance
- Superior corrosion resistance with Black-Oxide 18-8 Stainless Steel construction, ideal for harsh environments and reducing replacement frequency
- High tensile strength of 70,000 psi ensures reliable load-bearing capacity and prevents mechanical failure in demanding applications
- Fine UNF threads with Class 2A fit provide precise engagement and vibration resistance for secure, long-lasting assemblies
- Fully threaded 5/16" length offers maximum grip and uniform clamping force across the entire fastener
- Pan head with No. 0 Phillips drive allows for easy installation and a low-profile, rounded finish that minimizes snagging
- Rockwell B70 hardness maintains thread integrity and resists wear during repeated use or adjustments
- Compliance with ASME B18.6.3, RoHS 3, and REACH guarantees consistent quality, safety, and environmental responsibility
Professional Applications & Engineering Value
This 0-80 UNF machine screw is engineered to address critical challenges in precision assemblies where space constraints and corrosion are concerns. The Black-Oxide 18-8 Stainless Steel material provides an added layer of protection against oxidation and chemical exposure, making it suitable for electronics, instrumentation, and marine equipment. The fine thread design and Class 2A thread fit ensure tight tolerances and reduce the risk of loosening under vibration, which is essential in automotive or aerospace components. With a fully threaded shank and pan head style, it delivers uniform stress distribution and easy installation with standard Phillips drive tools, streamlining maintenance and assembly processes in industrial settings.
Specification Summary & Compliance
This screw features a 0-80 UNF fine thread with Class 2A dimensional accuracy, ensuring precise fit and interchangeability. It is manufactured in accordance with ASME B18.6.3 standards and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to environmental and safety requirements for global industrial use.
