Professional Applications & Engineering Value

This 8-32 UNC flat head Phillips screw delivers exceptional engineering value in applications where both secure fastening and reliable sealing are critical. The combination of 18-8 stainless steel material and passivated finish provides outstanding corrosion resistance, making it ideal for harsh environments including marine, chemical processing, and outdoor equipment. The integrated Buna-N rubber O-ring creates an effective seal that prevents fluid and gas leakage while accommodating thermal expansion and vibration. The undercut flat head profile with 100° countersink ensures flush mounting in panels and enclosures, while the fully threaded design and Class 2A thread fit guarantee consistent clamping force and vibration resistance in assembly lines, electrical enclosures, and fluid handling systems.

Specification Summary & Compliance

This sealing screw features precision 8-32 UNC coarse threads with Class 2A thread fit for consistent dimensional accuracy. The manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring material safety and sustainability. The screw maintains 70,000 psi tensile strength and is designed for maximum hole diameter of 0.179" with complete threading from head to tip for optimal fastening performance.
