• High tensile strength of 70,000 psi provides reliable fastening integrity under heavy loads and vibrations.
• Easy installation and removal with Phillips No. 2 drive and fully threaded UNC coarse thread design, reducing assembly time and effort.
• Precise Class 2A thread fit ensures smooth engagement and consistent performance in standard UNC 8-32 threaded holes.
• Compliance with RoHS 3 and REACH standards guarantees environmental safety and regulatory acceptance for global industrial applications.
• Versatile pan head profile offers a low-profile, rounded design that distributes clamping force evenly and resists tampering.

Professional Applications & Engineering Value

Engineered for high-pressure sealing applications, these 8-32 UNC rounded head Phillips screws solve critical leakage issues in industrial equipment, hydraulic systems, and automotive assemblies. The 18-8 stainless steel material combined with a passivated finish resists corrosion from chemicals and moisture, extending service life in aggressive environments. The integrated silicone rubber O-ring creates a reliable seal against fluids and gases, maintaining integrity under 6000 psi pressure and extreme temperature fluctuations from -80° to 400°F. This makes them ideal for pumps, valves, and compressed air systems where failure is not an option. The fully threaded coarse UNC design ensures quick installation and secure holding power, while the Phillips drive allows for efficient torque application with standard tools, streamlining maintenance and reducing downtime.
