Professional Applications & Engineering Value

These 6-32 UNC flat head Phillips screws with integrated Buna-N rubber O-rings deliver critical sealing performance for industrial applications where fluid containment and environmental protection are paramount. The 18-8 stainless steel construction with passivated finish provides exceptional corrosion resistance, making these fasteners ideal for marine, chemical processing, and outdoor equipment applications. The combination of Class 2A thread fit and fully threaded design ensures consistent sealing along the entire engagement length, while the 100° countersink angle creates a flush surface that prevents snagging and maintains aerodynamic profiles. These sealing screws effectively replace traditional fastener-and-gasket assemblies, simplifying inventory and installation while providing reliable performance across the -40° to 225°F temperature range where many elastomers fail.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit and UNC coarse thread specifications, these screws ensure consistent performance and interchangeability. The fully threaded design with right-hand thread direction provides maximum engagement in materials up to 0.152" maximum hole diameter. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures these fasteners meet current environmental standards for restricted substances, making them suitable for global supply chains and regulated industries.
