A good quantity of locknuts.
The '300pcs Locknuts Assortment Kit M3, M4, M5, M6, M8, Hex, 304 Stainless Steel, Metric, Nylon Insert' arrived in a plastic storage case. This is a nice set of lock nuts and it has 4 sizes that I use, M4 to M8. In use they fit as expected with the nylon preventing rotation, and if they are like any I have used in the past, they can probably be used a few times before the nylon becomes ineffective at stopping movement, which means it becomes just a nut at that point.

Excellent for 3D Printing!
You had me at M3 Locknuts to begin with, its essential for anyone 3d printing functional tools! These screw on so nicely to the threaded M3 screws that its almost as if they are oiled! Smooth slide and less fumbling around with trying to align it properly. There is 105 M3 screws which is perfect, the least is the M8 of course due to the size, its all packaged into a nice plastic container, which is perfect to keep on the side of the printer. Overall very satisfied, and glad to know that its not equally split between the sizes!
