- Precise thread engagement with Class 3A fit and UNF fine threads, providing reliable, vibration-resistant connections.
- Easy installation and removal using the 5/64" hex drive, allowing efficient maintenance in tight spaces without a protruding head.
- Compliance with industry standards including ASME B18.3, ensuring consistent quality and performance in engineering applications.
- Environmental and safety adherence through RoHS 3 and REACH compliance, supporting sustainable and safe manufacturing practices.
Professional Applications & Engineering Value
This 8-36 UNF Class 3A set screw is engineered to address common industrial challenges such as component slippage and corrosion-induced failure. Made from high-strength Alloy Steel with a Black-Oxide surface treatment, it offers enhanced protection against rust and oxidation in demanding settings like machinery, automotive, and aerospace assemblies. The headless design with a hex drive allows for flush mounting in confined areas, while the cup point tip bites securely into shafts or hubs, preventing loosening from vibrations. Its fine thread spacing and right-hand thread direction ensure tight, precise fits, making it ideal for permanent fastening in precision equipment where reliability is critical.
Specification Summary & Compliance
This set screw features a Class 3A thread fit for high precision in UNF threads with fine spacing, adhering to ASME B18.3 specifications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
