S-93802A548 6-32 x 1 1/4" MIL-DTL-18240, NASM3212, NASM82496 Sealing Thread-Locking Stainless Steel Pan Head Phillips Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking with permanent Nylon Patch thread locker, maintaining secure fastening from -40° to 225° F
• Reliable sealing performance under high-pressure conditions up to 6000 psi, thanks to the integrated silicone O-ring with a wide temperature range (-80° to 400° F)
• Exceptional corrosion resistance from 18-8 Stainless Steel with passivated finish, ideal for harsh industrial environments
• High tensile strength of 70,000 psi ensures durable, long-lasting connections in demanding applications
• Easy installation and removal with standard Phillips No. 2 drive and fully threaded UNC coarse threading for quick assembly
• Precise thread fit (Class 2A) for consistent engagement and reduced risk of cross-threading in 0.15" maximum hole diameters
• Compliance with MIL-DTL-18240 standards and environmental regulations like RoHS 3 and REACH, ensuring quality and safety

Professional Applications & Engineering Value

This 6-32 x 1-1/4" pan head screw combines 18-8 Stainless Steel construction with advanced sealing and locking features to address common industrial challenges like vibration loosening and fluid leakage. The Nylon Patch thread locker provides a permanent, reusable lock without requiring additional adhesives, while the silicone O-ring creates an effective seal against moisture, dust, and high-pressure fluids up to 6000 psi. Its Phillips drive and UNC coarse threads facilitate quick installation in tight spaces, making it ideal for industrial machinery, automotive assemblies, and electronic enclosures where reliability under extreme temperatures and pressures is critical. By integrating these elements, it reduces maintenance needs and enhances operational safety in sealing applications.
