Professional Applications & Engineering Value

This 6-80 ultra fine thread set screw delivers exceptional engineering value in applications requiring precise thread engagement and reliable clamping force. The 303 stainless steel material provides excellent corrosion resistance for machinery, medical devices, and electronics exposed to moisture or chemicals. Its Class 3A thread fit ensures tight tolerances that prevent loosening under vibration, while the alloy steel ball tip creates permanent dimples in shafts without damaging components. The headless design with hex drive allows installation in space-constrained assemblies, making it ideal for precision equipment, adjustment mechanisms, and permanent fastening solutions where disassembly isn't required.

Specification Summary & Compliance

This set screw features precision 6-80 UNS ultra fine threads with Class 3A fit for exact tolerance control. The 1/2" length and 0.138" thread diameter provide optimal engagement depth. Manufactured to industry standards with right-hand thread direction and 5/64" hex drive. Fully compliant with RoHS 3 (2015/863/EU) with exemption 6(c) and REACH (EC 1907/2006) regulations for environmental safety.
