okay, I'll play....... even though my father in law pokes fun at me for being better stocked than the local hardware store....
For years I kept my bolts in coffee cans. I painted the outsides so that I could use sharpies to mark the size within.
I even built shelves to specifically fit the cans.
Eventually I realized that I still did NOT have all the bolt sizes I needed, and saw all the wasted space of cylindrical cans on rectangular shelves.....
Then I found this cabinet at my local used tool place:
Obviously on the door we play with magnets to make faces.......and the framed picture on the door shows where small bolts come from!
Stored under the cabinet is my router table that I pull out and use on saw horses.
Within the cabinet the middle section holds hex-head bolts in imperial and metric, then socket-head cap screws (again in imperial and metric),
Also thrown in between sections are various carriage bolts, lag bolts, dowel pins, eye bolts, etc.
Inside the left door is mostly washers, nuts, and some more random stuff....
Inside the right door are large drill bits (MT2 and MT3 shank), three sets of transfer punches (imperial, metric and numbered) and hanging there are also some "Thread ID" types of bolt gauges:
The bottom half of the right door is more random stuff:
Here's some detail of the large drill bit holders. All are just steel angle frames and appropriately sized plastic or aluminum tube. The drill bit tips sit against some plywood strips so they don't dull:
These plastic bins are all removable so taking a bin or three to the bench is easy.
As for stocking the cabinet:
When I need a bolt and see a whole box selling cheap I buy the box.
I also remove and keep fasteners before I scrap or junk anything (blenders, treadmills, vehicles, etc.)
When I still need to order a certain size or length I will buy extras to help shore-up my stock.
I recently discovered a site where I do not have to pay the insane US shipping fees for fasteners:
https://www.boltsplus.ca/index.php
For me this has been a fantastic addition to the shop.
Many times I can find the exact fastener I need without adding it to the list for the next hardware store trip, or online order.
