Personally,i'm thinking of my Weber "Fern" bridge which can be adjusted up / down whilst under full string pressure.(pic.below) The screw threads on the bridge have integral,small brass hexagonal nuts at the base,which, using a Weber supplied wrench can be turned.However,the nuts are brass & the wrench is steel,one slip (i made several, as these are only about 1/16" thick) & the hexagonal nuts are missing a few corners. Why the heck weren't the threads + nuts made from steel as well ?. To me it makes as much sense as a chocolate teapot. In the case of a 'soft' truss rod nut,if it was to be overtightened & the hexagon corners were stripped off by the wrench - how do you loosen it,especially when typically there's usuall very little room around it to begin with ?. Far better IMHO,to have a strong hexagonal nut = steel,& to give an opportunity to reverse such a situation,or you could end up with a neck
under full compression & no way to relieve it,

"Makes as much sense as a chocolate teapot"! I agree I'd prefer a decent steel nut as well.
