Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical performance in demanding industrial applications where vibration resistance and precise positioning are paramount. The nylon patch thread locker effectively prevents loosening under continuous stress, while the UNC coarse thread spacing ensures rapid installation and superior holding power in machinery, automotive assemblies, and heavy equipment. Engineered with Rockwell C45 hardness, it maintains structural integrity under high torque loads, and the headless design allows for flush mounting in space-constrained applications. The black-oxide surface treatment provides an additional layer of corrosion protection, extending component life in challenging environments where moisture and chemicals are present.
Specification Summary & Compliance
This 1/2"-13 UNC set screw features Class 3A thread fit for precision tolerance, coarse thread spacing, and right-hand thread direction. Manufactured to meet ASME B18.3 standards (ASTM F912) with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe and reliable use across global industrial markets.
