Professional Applications & Engineering Value
This 7/8"-9 UNC Class 3A set screw is engineered to solve critical challenges in industrial assemblies where vibration resistance and precise component alignment are paramount. Its 18-8 stainless steel composition offers excellent corrosion resistance, making it suitable for outdoor equipment, marine applications, and chemical processing plants. The hex headless design with a 1/2" drive allows for flush mounting in tight spaces, while the coarse thread and cup tip ensure maximum grip on shafts and collars, preventing rotational loosening. By combining Rockwell B80 hardness with a right-hand thread direction, it delivers reliable performance in high-torque scenarios, reducing maintenance needs and downtime in conveyor systems, motors, and heavy machinery.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit for precise dimensional accuracy under the UNC thread type system, with a thread diameter of 0.875" and length of 1". It is manufactured in compliance with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, ensuring environmental safety and material reliability.
