Effect of Spring Pin thru Heavy Hex Nut
(OP)
We are installing a monorail system with track switches. The switches will be hung with rods and braced against lateral movement. A hanger fitting will be used at each mounting point, with the rod and nuts as shown. Is there any problem with drilling thru the nut and inserting a pin?
Thanks.
Thanks.

But, why would you want to do that in the first place when there are so many better faster easier cheaper ways to prevent a nut from "backing off", whatever that may mean to you.

Drilling a nice, straight, and centered hole in the end of a springy rod, up in the air, may be a "big ask".
Removing that pin after a few years in the weather might turn into a party...seized pin in the end of a springy rod, up in the air.

The spring pin method will likely be equally expensive when you have to hand drill every single nut and bolt in your assembly, assuming your assembly crew makes more than a few dollars per hour.
Tab washers, liquid threadlocking compound, and other methods will solve your problem. If it were me, stainless steel (or high strength, depending on loading conditions) prevailing torque nuts would get the nod.
