A couple of these and a five gallon bucket can get any workshop organized.

I find these really helpful especially if you are using multiple screw lengths or types. We also use them for wire nuts, nails and the like. SO why 4 stars? I must admit if your a one man shop you might find a parachute bag a better option but if you are part of a crew and sharing materials then this is your best choice

This set of four stacker system, with four compartments each, has greatly aided me in trying to keep my shop organized with the various screws, nails and brads that I use in my craft business. Each compartment is labeled and I know that the exact item that I am looking for is in the "screw" bucket. It has eliminated the boxes of stuff from piling up on the workbench.

Better yet, when I go off to a craft show, I just take the bucket with me, and I know I have everything in hand that I could possibly need. Plus, when the supply of a compartment gets low, I know it is time to fill it up, rather than hunt through the various boxes on the work bench hoping that I have more.

A great "investment" and time saver for me.

Although I am not too fond of the price that Bucket Boss is getting for these handy trays, I own about half a dozen of them. That's because they work so well!

The other reviewer pointed out the weight problem when over loaded. This is very true.

My buckets usually sit in my storage building full to the brim with assorted yet sorted fasteners. I can find what I am looking for rapidly by just lifting the stacking trays one at a time and giving a quick glance.

These plastic trays are very durable, and downright ingenious. The only thing is that if you get a whole bucket filled with trays, and all the trays filled with screws, nails, bolts, etc; the bucket will be incredibly heavy for the average person. If it is to stay stationary in your shop or garage, it is the perfect thing for you. If you plan on adding the other outside bucket tool organizer, and filling it with tools, with the full trays inside, and are going to work out of it, plan on one heck of a load to haul. Just consider this before you go off and make a purchase. Other than that, bucket trays will provide years of durable service, and save hours of time in some cases in looking for the perfect fastener, or craft item (yes, the whole family can use them for many purposes).
