Heim joint thread size?

[G-reg]

I'm trying to figure out which heim joint to order for the connecting rod on the shifter.. rearsets are Vortex off an RC51.  I know an M6 bolt fit in it when I tested it last night and I thought it was M6x20 (at least thats what it said on the bin!), but I'm looking online at mcmaster-carr and all I can find are M6x1. 

Anyone know which one its supposed to be and where to find 'em?

most likely an M6x1 20mm long bolt is what you had.
most hardware stores don't list the thread pitch witch would be 1mm they list just the diameter 6mm and length 20mm.
