S-92360A214 10-24 x 3/8" ASME B18.3, ASTM F835, MIL-DTL-18240 Thread-Locking Steel Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking with nylon patch thread locker maintains secure connections in dynamic environments from -70° to 250°F
• Exceptional tensile strength of 120,000 psi ensures reliable performance under heavy loads and stress conditions
• Superior corrosion protection through black-oxide coating on alloy steel extends service life in demanding industrial applications
• Precise Class 3A thread fit provides tighter tolerances for improved assembly accuracy and reduced cross-threading risks
• Optimized drive engagement with hex drive design allows for higher torque application and easier installation in confined spaces
• Full threading coverage along the 3/8" length enables maximum grip strength and uniform load distribution
• Enhanced durability with Rockwell C39 hardness resists wear and deformation during repeated use cycles

Professional Applications & Engineering Value

These 10-24 UNC screws with nylon patch thread locker solve critical vibration-induced loosening problems in machinery, automotive, and aerospace assemblies. The black-oxide alloy steel construction provides essential corrosion resistance while maintaining the 120,000 psi tensile strength required for structural applications. The coarse thread spacing and Class 3A thread fit ensure rapid installation with minimal cross-threading risk, reducing assembly time and improving production efficiency. The rounded button head profile offers a low-profile finish that clears obstructions while the hex drive accommodates standard tools for maintenance accessibility. These engineered fasteners deliver reliable performance in temperature-cycling environments from -70° to 250°F, making them ideal for engine components, industrial equipment, and electronic enclosures where vibration resistance and thermal stability are paramount.
