600pcs M6 M5 M4 M3 Hardware Nuts and Bolts, Machine Screws with Flat Washers, 304 Stainless Steel Metric Bolt Assortment with Allen Washers Sets

The media could not be loaded.  Good value for money, they come in a 24-section box with every size screw, washer, nut and hex wrench in a sealed bag. As mentioned above, you will get 4 hex keys. However, this is not a problem for me, but the box contains the following sizes of M3, M4 , M5 and M6 washers, nuts and captive screws of 20 mm, 16 mm, 12 mm, 8 mm each. All sizes allow the nut to be turned all the way up until it fits snugly into the head. The threads are smooth and burr-free, with a very smooth surface finish.

I use this a lot. It's a great quality kit. Very useful. Will buy another when I get low.

Good value for the price. I can tell they are good quality from looking at the threads and smooth surface. They are all sturdy and fit nicely. I would recommend it to others

I have already used this to replace the bolts on my motorcycle battery and slip-on exhaust bracket. Very handy.

Buy the whole box it is cheaper

Well made. Threads are good.

these screws are solid. they are strong enough for my applications. I have used them in many projects. 10/10

When I was mounting my TV i knew I needed M6 screws, but not sure exactly the length. If I had this, I wouldn't have to guess at all. With this , you'll be known as the VESA expert because you'll have every size covered. But other than that, I'm not sure where I'll be using these. But at least I won't have to go to the hardware store for anything requiring an allen key in this size for the rest of my natural life! These allen key bolts have heads that protrude a bit far from the base so be aware of that. Also comes with allen wrenches, but I would have more appreciated a hex bit tip thing. Everyone has a billion allen wrenches from flat pack furniture adventures, but not all hex tip sets have the appropriate allen key size.The case has 2 clips (the kind that are part of the box and have a thin portion of plastic that doubles as a hinge) and would probably weaken and break if left out in the elements, so wouldn't recommend leaving it in the bed of a pickup truck or something like that.So far the nuts and bolts haven't stripped, and they go in smoothly. I can't say if they would seize up outside over time, but I'm planning to just use them indoors.They're nuts, bolts, and washers, and they work well for intended purpose. At these current gas prices it'd probably pay for itself in gas from not going to the hardware store, not to mention the actual nuts and bolts themselves. 5 stars.
