Professional Applications & Engineering Value

This 1 1/8"-7 UNC coarse thread set screw delivers critical engineering solutions for heavy machinery, industrial equipment, and permanent assembly applications. The steel construction with Rockwell B80 hardness provides exceptional resistance to wear and deformation under sustained loads, while the cup point design bites securely into mating surfaces to prevent rotational movement in shafts, collars, and gears. The external square drive enables high-torque installation without cam-out issues, and the Class 2A thread fit ensures reliable engagement even in slightly misaligned applications. These industrial set screws are engineered to maintain positioning integrity in demanding environments where vibration and shock loads would compromise inferior fasteners.

Specification Summary & Compliance

This 8-inch set screw features 1 1/8"-7 UNC coarse threads with Class 2A thread fit per ASME standards, providing optimal clearance for assembly while maintaining secure fastening. The product conforms to ASME B18.6.2 dimensional and mechanical specifications, ensuring interchangeability and reliability. Manufacturing complies with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, making it suitable for various industrial applications requiring environmental compliance.
