Professional Applications & Engineering Value
This black-oxide alloy steel set screw with nylon patch thread locker addresses critical industrial challenges where vibration-induced loosening compromises assembly integrity. The UNC coarse thread design ensures rapid installation and superior holding power in heavy-duty applications including machinery, automotive components, and power transmission systems. The Class 3A thread fit provides precise tolerance control, eliminating play in precision assemblies while the flat tip configuration delivers concentrated clamping force on shafts and collars. Engineered to withstand extreme temperature fluctuations and corrosive environments, this industrial set screw maintains reliable performance where standard fasteners would fail, reducing maintenance frequency and downtime.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with UNC Class 3A thread tolerances ensuring precision fit. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 1/4"-20 thread size with coarse spacing provides optimal engagement while the Rockwell C45 hardness guarantees mechanical durability. Meets ASTM F912 standards for quality assurance in industrial fastening applications.
