Professional Applications & Engineering Value

This hex headless set screw in 18-8 stainless steel is engineered to address critical challenges in machinery, automotive, and assembly systems. Its Class 3A thread fit and UNC coarse threading ensure precise alignment and resistance to loosening under dynamic loads, reducing maintenance needs. The cup point tip bites into shafts or components, providing superior holding power without damaging surfaces. With Rockwell B80 hardness, it maintains integrity in high-torque scenarios, while the corrosion-resistant material suits outdoor or chemically exposed settings. Ideal for permanent fastening in gears, pulleys, and couplings, this screw delivers reliability where failure is not an option.

Specification Summary & Compliance

This set screw adheres to ASME B18.3 specifications, with 1"-8 UNC coarse threads and Class 3A thread fit for tight tolerances. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety. Dimensions include a 1 1/2" length, 1" thread diameter, and right-hand thread direction, manufactured to consistent quality standards for industrial use.
