Great little screws
Bought for 3d printing. Primarily use sunlu PETG and these are great for any assembly needs. Good bang for the Buck and a pretty handy all around size

Decent quality and I like that you can buy them in specific sizes as needed.
I use a lot of these length bolts with things from the 3D printer. I like that these are available in bulk in specific sizes so I can stock more of these to match my use. They are decent quality and for the price they are a great choice. I use them to fill a kit and as I am building things. Works well with brass heat set inserts.
