Hi Mala, for a less intrusive alternative you can get just the nuts and bolts plug-in from Max's file repository.

Go to http://moi3d.com and click the link for Resources, inside there click the link for "Max's file archive". Then it's listed under "Scripts" > NutsAndBolts.v.0.96.2015.06.22.zip .

Instructions for installing a plug-in are in the FAQ here:
