Professional Applications & Engineering Value
These 18-8 stainless steel rounded head screws with integrated spring lock washers provide critical vibration resistance in demanding applications where loosening under dynamic loads is a concern. The passivated finish on both screw and washer creates a protective oxide layer that significantly enhances corrosion resistance in industrial environments exposed to moisture, chemicals, or temperature variations. The combination of 70,000 psi tensile strength and Rockwell B80 hardness ensures these Phillips pan head screws maintain structural integrity while the UNC coarse threads facilitate quick assembly in various materials. Particularly valuable for machinery, electrical enclosures, and automotive components, these fully threaded 8-32 screws deliver reliable fastening performance where vibration damping and corrosion protection are essential engineering requirements.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit and UNC coarse threads (8-32 size) ensuring consistent engagement. The 1/4" length features full threading for maximum fastening versatility. Compliant with ASME B18.13 specifications for dimensional accuracy and performance. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements for environmental safety and restricted substances.
