Professional Applications & Engineering Value
This 6-32 UNC set screw is engineered to address critical challenges in industrial assembly, where vibration resistance and corrosion prevention are paramount. The 316 stainless steel material offers exceptional resistance to chemicals and moisture, making it suitable for applications in marine, chemical processing, and food equipment. Its headless design and hex drive facilitate installation in tight spaces, while the coarse UNC thread and Class 3A thread fit ensure a tight, reliable hold on components like shafts and collars, reducing maintenance needs and downtime. The 90° cone point provides concentrated pressure for secure positioning, ideal for precision machinery and automotive systems where slippage can lead to failures.
Specification Summary & Compliance
This set screw features a 6-32 UNC thread with Class 3A thread fit for high precision, a length of 1/2", and a coarse thread spacing. It conforms to ASME B18.3 specifications for dimensional standards and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring safety and environmental responsibility in industrial use.
