Loose rivet in Kwikee steps(SOLUTION)
I have a set of Series #32 Kwikee Steps on my rig, the bottom left side drops significantly more than the right side when you step on them. I have found that the top step on the left side has a loose...

Grade eight tend to have Radiused Rolled Root Threads - rolled not cut.
Rather than pien, a nylock nut works great. For absurdly rude vibrating parts a distorted Stover Lock Nut holds tighter than a nylock, meaning it does not rely on clamp tension. Stovers are sometimes used on pliers' pivot points.
Something a lot of people are not aware of: High carbon grade eight fasteners corrode significantly easier than common grade five. Even when they are plated.
I had to really learn how to hot rivet when I repaired Delco 50 DN bus alternators and on the extreme other end replace rectifiers in Hitachi, ND and Mutibishi alternators. Eight dollars bought 200% higher capacity diodes at 1/5th the cost
Anyway, used as shafts where shear resistance is important radius rolled root threads tend to fracture a lot less at the bottom of the thread than V cut threads.
