Professional Applications & Engineering Value
This 8-32 UNC set screw is engineered for demanding industrial applications where precision and durability are critical. Manufactured from 18-8 stainless steel, it offers excellent corrosion resistance, making it suitable for machinery, automotive, and electronic assemblies exposed to moisture or chemicals. The Class 3A thread fit ensures tight tolerances and superior clamping force, preventing loosening under vibration—a common challenge in dynamic systems. The hex headless design allows for flush mounting in confined spaces, while the silver soft tip minimizes damage to shaft surfaces, preserving component integrity. Ideal for securing gears, pulleys, and collars, this set screw delivers reliable performance in right-hand coarse thread applications, supported by ASME B18.3 certification for consistent quality.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including a Class 3A thread fit for tight tolerances and UNC coarse threads (8-32 size) with a diameter of 0.164". It meets ASME B18.3 specifications for manufacturing consistency and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are upheld.
