Professional Applications & Engineering Value
This 3-48 UNC set screw delivers exceptional engineering value for precision assembly applications where space constraints and corrosion resistance are critical factors. The 18-8 stainless steel construction provides excellent resistance to oxidation and chemical exposure, making it ideal for medical devices, electronics, and marine equipment. The hex headless design with 0.050" drive allows for compact installations while maintaining high torque capability. The cup point tip creates permanent seating marks in shafts and collars, preventing component slippage in high-vibration environments. With coarse thread spacing and right-hand thread direction, this fastener offers quick installation and reliable performance in automated assembly processes, reducing production time while maintaining joint integrity.
Specification Summary & Compliance
This precision set screw features a 3-48 UNC thread size with Class 3A thread fit for superior dimensional accuracy and tight tolerances. Manufactured to ASME B18.3 standards, the fastener ensures consistent performance and interchangeability. The product maintains compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global markets and environmentally conscious manufacturing operations.
