Note: The FC-3 screw specification is M3. The FC-4/ FC-4B screw specification is M4. The FC-6-1B/FC-6-2B screw specification is M6. B indicates that the color is black. L indicates that the length of the screw is extended.
A captive screw is used to fasten a faceplate or subrack. When you loosen the captive screw, it does not fall off. You can install a captive screw with your hand or with a screwdriver.
The captive screw can only used for the class A and B environment and II structural parts of class C environment, cannot used for I structural parts.
A captive screw consists of the knob, anchor rivet sleeve, screw, and spring. See Figure 1.

According to the requirements specified in the DKBA 2332 Environmental Specifications for the Materials Purchased by Huawei.
The appearance should be clean and flat and the straight veins of the aluminum sleeve are clear without cracks.
Stainless steel part: meet the corrosion resistance of stainless to DKBA04500067 Requirement for Conversion Coating on Metals
Aluminum anodizing: meet the corrosion resistance of aluminum anodizing to DKBA04500067 Requirement for Conversion Coating on Metals
Electrolytic zinc-coated part: meet the corrosion resistance of electrolytic zinc-coated to DKBA04500066 Requirements for Metal Plating.
Captive screw assembled: an alternating hot and humid test is done for 6 cycles (6days) according to IEC 68-2-30 or GB/T2523.4, after the test there is no corrosion.
You need to use the standard tool matching the screw slot number. After you install the screw by using the fastening or loosening torque moment listed in the following table, no plating is damaged on the surface of the screw and the screw does not slip.
The screw must meet the requirement on the minimum damage torque moment.

Note: The rally that the internal and external jackets of the screw can resist is tested when the captive screw are tightened on a 5052–H34 aluminum plate
Captive screws installed well, in free state, screw is launched and rebounded smoothly.
After captive screws installed, screws are used in the part for 15 times, it is not allowed that spring can’t work in the process, and is not allowed to see white on the screw groove in black captive screws.
The inspection rule is applicable to the inspection of the incoming materials of Huawei and it must comply with the regulations of the Quality Dept. of Huawei. The undefined products are inspected in batch and the single sampling plan of the GB2828 batch inspection is used.
1. MPE Dept. of Huawei reserves the right to interpret the technical requirements.
2. If there is any disagreement, the arbitration is subject to the technical requirements.
