The Stainless Steel Pan Phillips Pre-Applied Patch Screw is a premium precision fastening solution designed to provide secure, vibration-resistant, and reusable threaded assemblies without the need for separate thread-locking compounds during installation. Featuring a Pan Head with Phillips drive, this screw offers excellent torque transmission, ease of installation, and a neat finished appearance.
The screw is factory-coated with a pre-applied nylon locking patch (or other prevailing torque patch), which creates controlled friction between the screw threads and the mating threads. This prevents loosening caused by vibration, shock, thermal cycling, and dynamic loads, while maintaining consistent clamp load throughout the service life.
Manufactured from Stainless Steel SS304 (A2-70) and SS316 (A4-70), these screws offer excellent corrosion resistance, high mechanical strength, and long-term durability, making them ideal for electronics, automotive, electrical equipment, machinery, medical devices, telecommunications, and industrial OEM applications.

The Stainless Steel CSK Phillips Pre-Applied Patch Screw is a premium precision fastening solution designed to provide flush surface installation, vibration-resistant performance, and secure threaded fastening without the need for separate liquid thread-locking compounds. Featuring a 90° Countersunk (CSK) Head with Phillips drive, the screw sits flush with the workpiece after installation, making it ideal for applications requiring a smooth, level finish.
Each screw is factory-coated with a pre-applied nylon locking patch (or other prevailing torque patch), which creates controlled friction between the screw threads and the mating threads. This locking feature effectively resists loosening caused by vibration, shock, thermal expansion, and dynamic loading, while maintaining consistent clamp load throughout the service life.
