This is a very unique sale. The home owner had a business in his basement that distributed industrial electrical parts and electrical automotive parts. The business was mostly mail-order or wholesale ( pre-internet). If you look through pic it may make more sense. There are:

cases of boxes of metric and standard machine screws of all kinds.

5 gal buckets of 5000 wire twist connectors

GM and ford fender clips.

Fuses for ford vehicles

1000 count tie...
