Both storage drawer wheels fell of the drawer

I ordered two wheel and shaft kits, assuming they would be complete with all the parts, they weren't. Each kit consisted of (1) shoulder bolt and (1) nylon wheel. However, there were no nuts or lockwashers in the kits. Luckily, I have a large collection of miscelleneous hardware and was able to match thread sizes and complete the repair. TOO bad the parts sheet is incorrect. I can foresee problems for folks not as equipped as I was.
