What is the difference between square and round heads

The nut holds the rail to the handguard of the weapon. Where as the rounded head of the bolt seats recessed in the rail to maintain clearance for any picatinny accessories.

Would this fit on an m&p 15? s&w

This rail system fits on any M-LOK handguard. If it has a M-LOK handguard then it will fit.

Will this fit a S&W .357 revolver short barrel?

I would say no. unless your revolver is drilled and tapped to accept picatinny rails

What is the center to center screw holes dimensions?

There are several pieces with varying sizes the smallest still has 2 screw points they are very versatile I applied all but 3 pieces to my weapon and have not had any issue with loosening etc.
