Generally, we do not recommend using mechanical fasteners to attach LED modules to a cooling surface as they can warp or twist the board, which can cause cracking of the solder joints, which are key to ensuring that the LED is properly cooled. Instead, we recommend fastening LED modules to a suitable heatsink using double-sided thermal tape.
If you expect the module to experience heavy mechanical vibrations, a thermally conductive epoxy such as Arctic Silver may be the best option.
