If you need to transition between MTC2-N9151 devices quicker than replacing the M.2 fastener bolt, consider the Rapid Flash Base. It's compatible with either the MTC2-N9151 Breakout or UXplor carrier boards. Comes with clamp already assembled and board mounting screws, just add your breakout or UXplor to start your production line. Works fine for just making swaps easier when developing embedded applications :).
If you have a 3D printer, you can download the STL file here and build one yourself.
