Professional Applications & Engineering Value
This 6-40 UNF set screw is engineered to address critical fastening challenges in precision assemblies. The black-oxide alloy steel construction provides a robust barrier against oxidation and mild chemical exposure, making it ideal for machinery, automotive, and electronic enclosures where corrosion resistance is paramount. Its fine UNF threads and Class 3A fit ensure minimal backlash and superior clamping force, preventing loosening in high-vibration environments. The headless hex drive design allows seamless integration into collars, shafts, and gears without interfering with adjacent components, offering a reliable solution for set screw applications requiring consistent performance and long-term reliability under cyclic stresses.
Specification Summary & Compliance
This set screw adheres to UNF thread standards with a Class 3A thread fit for precise dimensional accuracy and tight tolerances. It is manufactured from alloy steel hardened to Rockwell C45, ensuring mechanical strength and wear resistance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial and engineering applications without hazardous substances.
