Professional Applications & Engineering Value

This 6-32 flat head Phillips sealing screw delivers critical engineering solutions for industrial applications requiring reliable pressure sealing. The combination of 18-8 stainless steel with passivated finish provides exceptional corrosion resistance in marine, chemical processing, and outdoor environments. The undercut flat head design ensures optimal O-ring compression, creating superior sealing performance that prevents fluid and gas leaks in hydraulic systems, pneumatic equipment, and fluid handling applications. The Buna-N rubber O-ring maintains elasticity across extreme temperature ranges from -40° to 225°F, while the fully threaded construction with UNC coarse threading provides maximum engagement and vibration resistance. This makes the screw ideal for panel mounting, enclosure sealing, and machinery where pressure integrity is critical.

Specification Summary & Compliance

This sealing screw features precision UNC coarse threading with Class 2A thread fit for consistent installation performance. The 6-32 thread size and 1/4" length maintain dimensional accuracy per industry standards. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory compliance for industrial applications worldwide. The screw is designed for maximum hole diameter of 0.152" with 100° countersink angle for proper seating and sealing performance.
