Professional Applications & Engineering Value
These 0-80 UNF fine thread machine screws deliver critical performance in precision assemblies where vibration resistance and corrosion protection are paramount. The 18-8 stainless steel composition combined with passivated surface treatment creates a durable barrier against chemical exposure and atmospheric corrosion, making them ideal for electronic enclosures, instrumentation, and medical devices. The rounded head design with slotted drive prevents snagging while providing sufficient torque transmission for secure fastening. With fully threaded shanks and Class 2A thread fit, these screws maintain consistent clamping force in applications requiring fine adjustment capabilities and reliable thread engagement in thin materials.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread tolerances for precise fitment. The UNF 0-80 fine threads provide 80 threads per inch with right-hand orientation. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe use in regulated industries. Mechanical properties include Rockwell B100 hardness and 100,000 psi tensile strength for demanding applications.
