Sportsman a arm bolts loose fix??

Hey guys. A couple months ago, 3 of us did a bit of riding for 4 days. Well into day 3 my friend riding a 14 570 had his right side lower aft a arm bolt fall out causing the arm to fall out as well as the cv joint. I checked mine and I had 2 loose bolts. Our other friend had 2 loose and one was about to fall out on his 12 500.

We tightened them with the fisher price wrenches in the kit and continued. 570 guy was done. Next day after about 70 more miles, 500 guys were loose again. One of mine too I think. Can’t remember exactly.

Tightened again and ride a bit more and all was well since. No riding lately though.

My question—obviously the locking feature of the lock washers on the a arm bolt are not working. Has anyone replaced the washers with another kind to prevent this from happening?

I was throwing around the idea of nord lock washers ( google it) unless someone had some other fix etc

Let me know what you all have done!!

Thx
