Professional Applications & Engineering Value

These 0-80 UNF flat head screws are engineered to address common industrial challenges, such as corrosion-induced failure and thread stripping in fine-pitch applications. The Black-Oxide 18-8 Stainless Steel construction provides excellent durability against moisture and chemicals, extending service life in electronics, aerospace, and precision machinery. The UNF fine thread and Class 2A thread fit ensure tight, secure fastening in thin materials, reducing the risk of loosening under vibration. With a Rockwell B80 hardness and fully threaded design, they deliver consistent performance in assemblies requiring high-strength, low-profile fasteners, making them ideal for compact devices and regulatory-compliant projects.

Specification Summary & Compliance

This screw adheres to ASME B18.6.3 specifications, ensuring dimensional accuracy and interchangeability. The UNF thread with Class 2A fit provides precise tolerances for reliable engagement. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), meeting environmental and safety standards for hazardous substances. Manufactured with a standard flat head profile, 100° countersink angle, and right-hand thread direction, it supports consistent industrial use.
