280pcs Metric M3 7-Sizes Nylon Phillips Pan Head Screw Nut Assortment Kit，Screw M3x 6mm 8mm 10mm 12mm 15mm 20mm 25mm, Nut Hex M3 (Black)

These are plastic, make sure that is what you need.

Good assortment of M3 nylon screws an nuts for a good price. Promptly delivered.

Many sizes to suit my needs now and plenty for any future needs as well. Nice container to hold them as well. The nylon nuts screw right on with no issues.

Nice assortment but it may be a consideration to just order the size you need.

I would recommend this seller & product to others.

These are well made and is exactly what I needed.

This selection does NOT include any standoff spacers. I had previous seen spacers referred to as "standoffs", which this has in its description, but contains only screws and nuts. Worthless to me.

Although I will not be using the product, it seems like decent quality. The issue is probably a result of my own ignorance, but it is an issue for me all the same. The sizes listed are for length of the screw, rather than the thickness of the screw. All of these screws have the same thickness, and are all quite thin.

Used for delicate parts. Another case of you get what you pay for, the heads of these strip off and the nuts are not made amazingly.
