So, my issue here is I'm trying to find a source for blank t-nut bar stock. The vise I have to mount on my vertical slide adapter is a smidge too wide and standard T-nuts don't have the bite in enough of the slot to support the vise entirely. Does anyone know of a source for this kind of material? 10 MM WIDE AT THE TOP OF THE T 15 MM WIDE AT THE BOTTOM OF THE T. Any help is much appreciated. Thanks
