Detailed Specifications
FEATURES:
1. CPS remains captive to the panel when the panel is removed.
2. CPS is color-matched with the mounting surface which eliminates distraction from the information display by blending with the background.
3. Allows up to .06 inch circular mismatch of panel clearance hole alignment with fixed threads in hardware plate.
4. The one piece screw and washer simplifies handling, installation and removal of attachment hardware.
5. May be installed and removed without use of special tools, or damage to either the host panel or the CPS.
6. Screw head is finished with a durable color coating that is resistant to abrasion and screwdriver damage. This feature virtually eliminates the need for touch-up painting after assembly.
7. A self-locking feature to prevent vibration from loosening the screw is achieved by the compression effect of the nylon washer between the screw head and the panel.
8. CPS is recommended for use with Type BA or BB pressure displacement STAKE FASTENERS.
NOTES:
1. The screws listed in this series reflect aircraft quality with emphasis on the forming of the Phillips recess to meet design specification.
2. Care should be exercised to assure that the screwdriver tools meet the same quality and design specification in order to eliminate mismating and subsequent damage to the drive recess and coating material.
SPECIFICATIONS:
1. The screw head dimensions & recess are based on NAS601 series. The screw material is heat treated alloy steel, 4037, 4140, 4340 or 8740.
2. Screws and captive metal washer are cadmium plated per QQ-P-416, Type II (yellow), Class 2 or zinc plated per ASTM B633, Type II (yellow) Class SC2
