Professional Applications & Engineering Value
Engineered for precision and durability, these 0-80 UNF fine thread machine screws address common challenges in electronics, instrumentation, and aerospace assemblies where space is limited and reliability is critical. The Black-Oxide 18-8 Stainless Steel construction provides an added layer of corrosion resistance, reducing maintenance in humid or chemically exposed settings. The pan head design with Phillips drive allows for efficient installation without specialized tools, while the fully threaded body ensures consistent holding power across the entire length. This combination of high tensile strength and fine threading makes them ideal for securing sensitive components that require vibration resistance and long-term performance without failure.
Specification Summary & Compliance
This screw adheres to Class 2A thread fit per UNF standards, ensuring precise dimensional accuracy and interchangeability. Manufacturing follows ASME B18.6.3 specifications for consistency and reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances and supporting sustainable procurement practices.
