Professional Applications & Engineering Value
These 1/4"-20 UNC set screws deliver exceptional engineering value in precision assembly applications where vibration resistance and permanent positioning are critical. The 18-8 stainless steel composition provides excellent corrosion resistance for demanding environments, while the cup point design creates deep indentation in shafts and collars, preventing rotational slippage even under high torque conditions. The hex headless configuration allows for flush mounting in space-constrained assemblies, and the Class 3A thread fit ensures precise engagement with mating components. These features make these set screws ideal for precision machinery, automotive components, industrial equipment, and aerospace applications where reliability and dimensional accuracy are paramount.
Specification Summary & Compliance
This 1/4"-20 UNC set screw features precise Class 3A thread fit with coarse thread spacing for optimal engagement. Manufacturing complies with ASME B18.3 specifications for dimensional accuracy and performance standards. The product meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and material safety. With Rockwell B80 hardness and right-hand thread direction, these fasteners deliver consistent performance across industrial applications requiring reliable set screw solutions.
