Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical engineering solutions for demanding industrial applications. The Class 3A thread fit provides superior vibration resistance in machinery, preventing loosening in high-stress environments. The coarse UNC thread form ensures rapid installation while maintaining structural integrity, particularly valuable in production lines where time efficiency matters. The cup tip configuration creates concentrated pressure points for secure component positioning on shafts, pulleys, and gears. Combined with Rockwell C45 hardness, this fastener maintains its clamping force under repeated stress cycles, making it ideal for heavy equipment, automotive assemblies, and industrial machinery where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to precise 1 1/2"-6 UNC coarse thread specifications with Class 3A fit for exceptional dimensional accuracy. Complies with ASME B18.3 and ASTM F912 manufacturing standards ensuring consistent quality and performance. Meets environmental regulations including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance for safe use across global markets. Right-hand thread direction and 1" length provide standardized installation compatibility with industrial components.
