Rean Tiny XLR RT4 MPR

I use Line6 radio mic gear and the beltpack for a headmic became unusable because the retaining nut for the socket came off and got lost - making the socket loose and in danger of damage. The retaining nut secured the socket into which the headmic miniXLR connector fits. It seems impossible to find the screw-thread info for the retaining nut/socket - no where - because I needed a replacement! So I started thinking out of the box and decided to locate a chassis mount miniXLR connector - and there it was: the Rean Tiny XLR RT4 MPR socket on the Thomann website. I was happy to pay the penalty of postage costs to get the low-cost Rean Tiny XLR RT4 MPR. It was well worth the cost compared to the inflated Line6 cost for the assembly containing the retaining nut. So although I've only used the nut rather than the whole chassis-mount socket, I'm very please with the solution - it fits perfectly. Incidentally, does anyone at Thomann know the screw-thread spec/size for the Rean Tiny XLR RT4 MPR?
