S-93802A725 10-32 x 3/8" MIL-DTL-18240, MS3212-31L, NASM3212, NASM82496 Sealing Thread-Locking Stainless Steel Pan Head Phillips Screws

Key Features & Benefits at a Glance

• Superior Sealing Performance: Withstands up to 6000 psi maximum pressure, ensuring reliable leak prevention in high-pressure environments.
• Exceptional Temperature Resistance: Operates reliably from -40° to 400° F thanks to silicone O-rings and nylon patch thread locker.
• High Tensile Strength & Corrosion Resistance: 70,000 psi tensile strength and 18-8 stainless steel construction provide durability in harsh, corrosive conditions.
• Vibration-Resistant Locking: Integrated nylon patch thread locker prevents loosening under dynamic loads, maintaining joint integrity.
• Precision Thread Fit: Class 2A thread fit and UNF fine threads ensure accurate, secure fastening with reduced risk of cross-threading.
• Easy Installation & Removal: Phillips drive (No. 2) and rounded pan head design allow for straightforward tool engagement and efficient assembly.
• Enhanced Durability with Passivated Finish: Passivated surface treatment improves corrosion resistance, extending service life in demanding industrial applications.

Professional Applications & Engineering Value

This 10-32 UNF rounded head screw is engineered to address critical sealing and vibration challenges in industrial and aerospace applications. The combination of a silicone rubber O-ring and nylon patch thread locker creates a dual-sealing mechanism that prevents fluid ingress and maintains clamp load under extreme temperature fluctuations (-40° to 400° F). Manufactured from 18-8 stainless steel with a passivated finish, it offers excellent corrosion resistance, making it ideal for harsh environments like hydraulic systems, pneumatic controls, and marine equipment. The fully threaded design and Class 2A thread fit ensure precise engagement, reducing installation errors and enhancing reliability in assemblies requiring consistent pressure containment up to 6000 psi.
