Professional Applications & Engineering Value

This 8-32 UNC rounded head sealing screw addresses critical engineering challenges in industrial environments where fluid containment and pressure integrity are paramount. The combination of 18-8 Stainless Steel material with passivated finish provides exceptional corrosion resistance, while the integrated Fluoroelastomer O-Ring creates a reliable seal against liquids and gases in high-pressure systems up to 6000 psi. The pan head design with Phillips drive offers both aesthetic appeal and practical installation efficiency. These fully threaded screws are engineered for applications requiring consistent sealing performance across temperature extremes from -20° to 400°F, making them ideal for hydraulic systems, pneumatic equipment, and industrial machinery where pressure sealing and corrosion resistance cannot be compromised.

Specification Summary & Compliance

This sealing screw features precision UNC coarse threads with Class 2A fit, ensuring consistent performance and interchangeability. The 8-32 thread size with 0.164" diameter and 1/2" length provides optimal fastening capabilities. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and regulatory compliance for industrial use worldwide. The passivated finish on 18-8 Stainless Steel enhances corrosion resistance while maintaining the material's inherent strength characteristics.
