Professional Applications & Engineering Value
This 1/2"-13 UNC steel set screw delivers critical engineering solutions for demanding industrial applications where maximum holding power is essential. The combination of coarse thread spacing and Class 2A thread fit ensures reliable performance in high-vibration environments common in heavy machinery, manufacturing equipment, and automotive assemblies. The cup point tip creates permanent indentation in mating surfaces, preventing rotational movement and maintaining precise alignment in pulley systems, gear assemblies, and coupling applications. Manufactured from Rockwell B80 hardness steel, this 5-inch set screw withstands repeated adjustments without deformation, making it ideal for permanent positioning applications where disassembly is infrequent. The external square drive design allows for high-torque installation using standard tools, reducing installation time while preventing drive stripping in production environments.
Specification Summary & Compliance
This 1/2"-13 UNC set screw features precise Class 2A thread fit with coarse thread spacing, manufactured to exacting inch system dimensions including 5" length and 1/2" thread diameter. The fastener complies with ASME B18.6.2 manufacturing specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance standards, ensuring both mechanical reliability and regulatory adherence for industrial applications.
