- Compliance with major industry standards including ASME B18.3, RoHS 3, and REACH, ensuring safety and regulatory acceptance.
Professional Applications & Engineering Value
This 8-36 UNF Class 3A Black-Oxide Alloy Steel set screw is engineered to address common industrial challenges such as component slippage, corrosion, and vibration-induced failure. The fine thread spacing and Class 3A thread fit provide tight tolerances for secure fastening in precision equipment, while the cup point tip bites into surfaces without excessive damage, making it ideal for securing gears, pulleys, and collars on shafts. The Black-Oxide surface treatment offers enhanced corrosion resistance, crucial for machinery exposed to moisture or chemicals. Its headless, hex drive design ensures easy access in tight spaces, reducing maintenance downtime and improving assembly efficiency in automotive, aerospace, and manufacturing applications.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit for high precision in the UNF (Unified National Fine) thread system, with a thread size of 8-36 and a length of 5/16". It meets ASME B18.3 specifications for dimensional accuracy and is manufactured from Alloy Steel with a Rockwell C45 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for use in various industrial and consumer applications.
