WalfrontM3 Screws Assortment Kit, M3 Button Head Screws, Grade 12.9 M3 Socket Head Screws Bolts Nuts Fastener Kit with Storage Case 4/5/6/8/10/12/16/20/25mm Length（280PCS）

Plastic shrink wrap around the case was broken and the case was cracked upon arrival. Two holes were on the bottom of the case that were large enough for the screws to fall out if the shrink wrap wasn't there. I suspect this was broken during transit as the broken pieces were still in the shrink wrap. For how brittle this plastic is, I would have expected this to be delivered in a bubble wrap lined envelope, but it wasn't.The plastic case is not impact resistant, dropping the case or even stepping on it would break or chip it.Otherwise, everything is still there and the screws themselves work fine.

No issues so far, working exactly as expected. I do wonder if a larger set would have been helpful but nothing has come up so far.

I paid a bit more for these screws than other kits were selling for, hoping to perhaps get something a little better than bottom of the barrel, but it didn't pay off. The screws come in a very flimsy plastic tray that was already partially broken on arrival. The compartments are segmented by removable walls that slide up and mix the contents if you even think about putting the slightest bit of upward force on them, and they also seem to shift in transport, so the nuts were spread out all across the box and had to be sorted. The entire box, as well as all of the bolts and nuts were coated and swimming in whatever lubricant in their production process, so get ready to wash your hands any time you come near these. This lubricant also paradoxically adds some friction against the side walls of the compartments in the tray, making it easier to accidentally drag them up.The bolts seem to be pretty consistent, but in a sample of 30 nuts, the width across flats varied from 5.39 to 5.46, with about half of the nuts being at 5.45. This is within spec, but if you have tight tolerances and expect consistent results, don't buy these. I had to go through about two dozen before finding three nuts that fit the first one I had measured and dimensioned for.

Great product. Variety of lengths. Just what I needed.

Nice Kit! These kits are great for building/repairing RC, robotics, 3d printers and CNC Machines.

Make sure you read the sizes. Pictures do not truly represent the actual sizes. Really not worth much unless you are working on very small items. The quality is Chinese so you know you are getting inferior quality.

They got the job done

Great!

Really filthy and full of oilAm i the exception...?Am i the only one with bad luck that just received a bad batch !?I'll let you be the judge

Very good quality of assorted m3 allenscrews and nut. Came in segregated box. The box was slightly damaged but the product is very good.Total value for money.

Muy malos, llega todos roto el empaque, con grasa, los tornillos no se sienten mal pero se podrian encontrar mejores.
