Professional Applications & Engineering Value

This 0-80 UNF fine thread socket head cap screw addresses critical sealing and precision fastening challenges in industrial equipment, fluid handling systems, and precision instrumentation. The 18-8 stainless steel body provides excellent corrosion resistance while maintaining Rockwell B85 hardness for durability. The integrated Buna-N rubber O-ring creates a reliable seal against fluids and gases, solving leakage issues in pressurized assemblies up to 1500 psi. The Class 3A thread fit ensures precise engagement in fine-thread applications where vibration resistance is paramount. Engineered with a standard socket head profile and hex drive, it facilitates installation in confined spaces common in aerospace, automotive, and hydraulic system applications where reliability under thermal cycling (-40° to 225°F) is essential.
