Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical engineering solutions for industrial equipment requiring vibration-resistant fastening. The combination of Class 3A thread fit with coarse UNC threading provides maximum resistance to loosening under dynamic loads, making it ideal for rotating components, machinery guards, and precision assemblies. The headless design with flat tip creates secure, flush connections in confined spaces, while the black-oxide surface treatment significantly enhances corrosion protection in manufacturing environments. Engineered to withstand high torque applications, this 1/2"-13 set screw maintains structural integrity through repeated maintenance cycles, reducing downtime and replacement costs in heavy-duty industrial applications.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit precision and UNC coarse thread spacing. The 1/2"-13 thread size maintains strict dimensional accuracy in inch system measurements. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial markets. The Rockwell C45 hardness rating verifies consistent material strength across production batches.
