Ariens Snowthrower Weight Kit- question about nuts & bolts

Hi all, may probably seem trivial, but I'm paranoid.  Due to the placement of the weight kit for the Ariens snowthrower (inside the 'bucket'), it would be somewhat catastrophic if a bolt nut vibrated loose and dropped into the augers while they're moving.  (Why this isn't designed to be mounted on the top I don't know).    
 
So here goes:  I purchased the kit from Jack's.    Instructions say the nuts are 5/16-18 center locking nuts.  And the bolts 5/6-18 1-1/2" hex bolt.  All seems logical.  BUT, I can't get the nuts onto the bolts.  They start on about a turn and a half before they lock up.  I tried both nuts on both bolts.  And they don't appear to my inexperienced eyes to be anything more than a standard nut.  
 
Are these some sort of locking nuts that I've never seen before, and I should just eat some spinach and turn them with a lot of force to try to get them on?  I haven't done that for fear of cross-threading.  I did pick up some 5/16 SS nut & bolts.  These purchased nuts thread easily on to the Ariens bolts.  The Ariens nuts do NOT thread on to the purchased bolts.  
 
Aha, with the google as my friend, I see that these 'center lock nuts' are really a thing, and the ariens nuts have the rectangular indents on the sides to prove it.  
 
So, should it be necessary to really force these things on or is there something wrong??  Thanks!!

    Yes they go on tight.
     
    Center locking actually has deformed threads and will deform the threads on the screws [bolts] as you install them. Basically it is like cross threading a screw to make nut/screw combination vibration resistance. 
     
    If you ever need to remove the nuts then the nuts and screws will need replacing as these center lock nuts really do a number on the threading of screws.

    Thanks, will be unabashed in my wrench turning without fear of crossthreading!!  Or more correctly with the express intent of crossthreading!!!
