Professional Applications & Engineering Value
This 8-36 UNF Class 3A set screw is engineered to address critical challenges in industrial and mechanical assemblies where space is limited and reliability is paramount. The headless design and cup tip allow for flush mounting and secure gripping, preventing component slippage in high-vibration environments like machinery, automotive systems, and precision instruments. Made from black-oxide alloy steel, it offers excellent resistance to rust and wear, while the fine thread spacing and right-hand thread direction ensure tight, accurate fits. With a Rockwell C45 hardness, it maintains integrity under stress, making it ideal for applications requiring repeated adjustments and long-term durability without loosening.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit for high precision in UNF fine threads, with a thread size of 8-36 and length of 3/16". It conforms to ASME B18.3 and ASTM F912 specifications, ensuring consistent manufacturing quality. Additionally, it is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety regulations for industrial use.
