Help locating a screw pin part number

[duffyanneal]

Hi, I was adjusting the links on my GMT Master II and marred up the face of one of the screw pins. It works fine, but I would like to install a new one.

Does anyone know the part number for the screw pin that attaches the band to the clasp on the safety clasp side? It is not the same size as the other bracelet screw pins. I measured it with digital calipers. Details are below. I did search the internet and here for the past couple of hours and could not find the any information. I did order a generic screw pin from ebay, but I'm not sure if the screw pitch is correct. Any assistance would be greatly appreciated.

Watch: GMT Master II 126710
Band: SS Jubilee (B20-69200-20-E1 or similar)
Screw pin dimensions: L: 14mm Dia:1.34mm Thread: 1.2mm
