When a Multi-Rail system is installed on the grid or blank platform, most typical way of installation is to use two shoulder bolts for positioning and DIN912 bolts for remaining holes.
Shoulder bolt requires a precise 12 mm hole. Additionally, bushings and/or threaded inserts can be used.
For the standard bolts simple M12 thread is needed. In aluminium platforms, threaded inserts are recommended.
Inserts and platforms are available through the OK-VISE global distribution network.
