Professional Applications & Engineering Value
This black-oxide alloy steel set screw is engineered to address common industrial challenges such as component slippage, corrosion-induced failure, and assembly inaccessibility. The Class 3A UNF fine thread provides tighter tolerances and superior resistance to vibrational loosening in precision machinery, automotive systems, and power transmission equipment. Its headless hex drive design allows flush mounting in bores and shafts, while the oval tip concentrates clamping force for secure positioning of gears, pulleys, and collars. The combination of high-strength material and protective coating ensures long-term reliability in demanding applications, reducing maintenance downtime and replacement costs.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit for precise dimensional accuracy and ASME B18.3 specifications for consistent manufacturing quality. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring the absence of restricted hazardous substances. The fastener is supplied in inch system measurements with a thread size of 3/8"-24 UNF, length of 5/8", and right-hand thread direction for standard industrial use.
