Professional Applications & Engineering Value
These 0-80 UNF Torx Plus rounded head screws are engineered for precision assemblies where reliability and space constraints are critical. The 18-8 Stainless Steel material, enhanced by a passivated finish, resists oxidation and chemical exposure, making them suitable for electronics, medical devices, and aerospace components. The Torx Plus IP5 drive minimizes tool slippage, allowing for higher torque application without damaging the screw head—essential for automated production lines. With a fine thread and Class 2A thread fit, these screws maintain tight tolerances in right-hand threaded applications, reducing the risk of loosening under vibration. Fully threaded along a compact 1/8" length, they provide uniform clamping force in thin materials, ensuring long-term performance in industrial screws and precision instruments.
Specification Summary & Compliance
This product adheres to ASME B18.3 specifications, with a Class 2A thread fit for consistent dimensional accuracy. The 0-80 UNF fine thread and right-hand threading comply with unified screw standards, while the fully threaded 1/8" length ensures reliable engagement. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming it is free of restricted substances for safe use in global markets.
