Detailed Specifications
FEATURES:
1. The one piece screw and captive washer simplifies handling, installation and removal of attachment hardware.
2. Attachment hardware, color-matched with the mounting surface eliminates distraction from the information display by blending with the background.
3. Screw heads are formed by cold forging, followed by a heat treating process which increases the basic tensile strength of the material. The resultant high tensile strength thus eliminates burring and yield of the
substrate under the coating material.
4. The thermosetting coating material used in combination with the relatively hard screw heads is resistant to abrasion and screwdriver damage. This feature virtually eliminates the need for touch-up painting after assembly.
5. The nylon washer provides a resilient cushion to protect the finished surface of panels and equipment.
6. 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.
7. A seal for moisture, low pressure gases and vapors can be affected between the screw head and the panel surface by the compression of the nylon washer.
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.
3. Inventory of all sizes listed in the table and stock colors listed in the forward section of this catalog are carried in stock to assure short lead times. Lengths not listed are also available on order.
4. For color-coated screw less washer, omit the letter P from the head type code.
SPECIFICATIONS:
1. Screws meet all requirements of NAS600 series, including thread size .086-56 and .216-24 which are not listed as part of the NAS specification.
2. Screws are stocked cadmium plated per QQ-P-416, Type II, Class 2.
3. Threads are in conformance with MIL-S-8879, except parts with thread codes “2C” & “12C” which are IAW MIL-S-7742.
4. Pan-L-Screws are suitable for applications with temperatures up to 250°F.
5. Washer color is achieved by molding with pigmented nylon per ASTM D4066.
6. Screw head coating and washer colors are matched to customer requirements. We recommend selection from FED-STD-595 whenever possible but we are also prepared to match customer-furnished color chips or samples.
