Professional Applications & Engineering Value
Engineered for precision-critical industries, this 0-80 UNF fine thread screw delivers exceptional performance in applications requiring minimal space and high reliability. The passivated 18-8 stainless steel offers excellent corrosion resistance, making it suitable for electronics, aerospace, and medical devices where exposure to moisture or chemicals is a concern. The rounded truss head distributes clamping force evenly, preventing damage to sensitive surfaces, while the fine thread design ensures secure fastening in thin materials and reduces the risk of stripping. With a Rockwell B70 hardness and 70,000 psi tensile strength, it withstands dynamic loads and vibrations, providing long-term durability in demanding assemblies. The Phillips No. 0 drive facilitates quick installation, enhancing efficiency in high-volume production environments.
Specification Summary & Compliance
This screw features a Class 2A thread fit for consistent engagement and ease of assembly, manufactured in accordance with ASME B18.6.3 specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material sustainability. The fully threaded 1/8" length and 0-80 UNF fine thread provide precise tolerance control, meeting rigorous industrial standards for reliability and performance.
