Recommendation? CKF Muscle Hardware Question

[DennisM]

I purchased a used but well cared for CKF Muscle. Its a very nice knife but it is missing the screw to attach the clip. I have a CKF Brat as well, that came with extra hardware in the pouch. I tried to use one of the screws contained in the extra hardware and it seems as though the hardware is not a standard size across CKF knives.

The questions I have is what is the screw size I need and where would I get a replacement w/o trying to communicate with a foreign company? Any help would be most appreciated. Thanks.

See attached pictures just in case the description of my need was not thorough enough.
