Usually scavenge every nut and bolt I can off of anything that's going to be scrapped. Saved me out of countless pinches later on and I barely ever have to buy nuts and bolts. I also take all the spares from work, now I have probably 300 hydraulic pumps and loads of expensive bearings I have absolutely no use for lol. I should put that shit on ebay though.
Same thing with electronics, I always grab cables and wiring I may use later. It's helped tons when doing electrical on the farm or on cars.
