Key Features & Benefits at a Glance
- Vibration-resistant locking with permanent Nylon Patch thread locker, preventing loosening in high-stress environments from -70° to 250°F
- Superior corrosion resistance from 18-8 Stainless Steel construction, ideal for harsh industrial and outdoor applications
- High-strength performance with 80,000 psi tensile strength and Rockwell B80 hardness for demanding mechanical assemblies
- Secure flush installation with standard 82° countersink angle and flat head design for smooth surface finishing
- Efficient coarse threading using UNC 1/4"-20 threads for faster installation and reduced cross-threading risks
- Reliable drive engagement with Phillips No. 3 drive style ensuring consistent torque application during assembly
- Full regulatory compliance meeting RoHS 3 and REACH standards for safe use in regulated industries
Professional Applications & Engineering Value
This 18-8 Stainless Steel flat head screw with Nylon Patch thread locking technology addresses critical vibration-induced failure points in machinery, automotive, and electrical enclosures. The passivated finish enhances corrosion resistance in humid or chemical-exposed environments, while the UNC coarse thread and fully threaded design provide maximum grip strength in softer materials and metals. Engineers specify these Phillips drive screws for their reliable 82° countersink seating in precision applications where surface flushness is mandatory. The combination of 80,000 psi tensile strength and wide temperature range locking makes them ideal for permanent assemblies subject to thermal cycling and dynamic loads.
