Glarks 510Pcs Metric M3 M4 M5 Alloy Steel Socket Cap Screws Hex Head Bolt Nuts Assortment Kit - Black Oxide Finish

Becareful. These screws/bolts are make with very weak metal. I broke like 5 of them in a night. I build electric skateboard as a hobby so my life is depends on these screws. I don't have much faith on these screws.

Last week when I went to the local hardware store for some metric machine screws I was shocked that they were selling two screws at $.96 US in individual plastic bags. I couldn't believe that price and I needed 20 screws. Imagine, 20 tiny M3 screws for $20 US after tax. Well, I found this company and seller and purchased this set of over 500 pcs for $5 US less. Needless to say, I am happy and still a little dumbfounded that a hardware store could get away with 1000% markup on something that should cost a fraction of a penny.This product came in a nice organized plastic holder with dividers so the parts would not mix. Also inside was a note from the manufacturer that if the parts did get mixed or if the holder was damaged that they were standing by to replace the whole thing. I like that in a company, its called accountability and anticipating the customer's needs.Though I have more metric screws than I will probably need for the foreseeable future, I would not hesitate to buy from and recommend others to buy from this company and this seller.

Before I bought this package of screws I used a screw gauge and measured to determine that I needed m4 screws. I didn't suspect that this kits thread count would be wildly different from what I needed but that was the case. This kit contains m4 screws with 0.7 thread count. I needed the ones with 0.5 thread count so these will not work. You would think that the seller might find it prudent to put the thread count in their advertising when it can vary.

I bought this to have a large array of spares for my R/C Car collection. The case that this comes in is great. Really secure latch system and good dividers. Not one piece of hardware in a section it's not suppose to be in. Compared to the factory fasteners on one of my cars, it seems that there is a slightly greater tolerance in the hex socket on these. This means you will want to ensure you're using good tools to ensure long lasting use without stripping anything out. This has already been put to use as I converted a chassis from Nitro to Electric and needed some additional fasteners in different lengths than I had.

Are they counter sunk screws? Yes.Will the dividers keep the screws separate? No way in hell.Possible the worse design I've come across to keep the divider WILL shift during shipping and anytime you open the case to get a screw..... yup the dividers will want to move up leaving you with a nice mix of m3-m5 screws that you get to pick through.... unless you 3d print your own case.I would have spent happily spent 2-3 more dollars to NOT have to A) realize the divider does nothing to keep the screws divided and B) design and print a case that actually keeps them apart.The devil is in the details and to ship this product knowing full well the divider is trash, well I cant give 0 stars so 1 star and noting Glarks products are a no-go.

This is a great little assortment. I needed some metric hex socket screws for a 3D printing project I'm working on, and was unsure of exactly what size screws I was going to need, so this assort was just what I needed. One reviewer complained about the plastic container that they come it, but I think it's actually very nice. The printed guide makes it easy to know which size is where. I actually have no need for the nuts, but perhaps I'll find a use for them another day. I would definitely buy this again if the need arises.

great little set to have around cause usually you don't know what you need til you need it. Great for custom projects. There were some bolts that had manufacturing issues like no threads or poorly made heads or the occasional nut with no threads. Took a star away for that and the fact the storage container is very light duty and when it showed up two of the partitions had come loose and mixed the bolts up. I put a drop of super glue on the partitions to hold them in place when I put the sorted out bolts back in

The idea of an assortment in a divided case is to keep it organized. This case is designed in such a with the dividers are removable in both directions, meaning nuts and bolts will work their way under the dividers and any attempt to separate them so you can close the case will mean you end up with a giant mess of random bolts

The screws got all mixed up in the box because the box is really bad. It just uses slots to keep screws separate and they easily come loose.The screws are not all black. About half the screws are a grey colour.The screws themselves are functional with as far as I can tell a decent thread.Buy something else with a better box and screws that are actually the same colour.

Happy with this purchase, just nice to have in my workshop if needed.

Sometimes when you order hardware online it's a gamble what you'll get. I am pleased to say that this product is as described and is very good quality. I have not found any misshapen pieces nor have I found any with bad threads.They even came in a much nicer case than they have pictured. I am pleased with my purchase and I can recommend this product.

It is hard to find metric screws in most of the hardware stores, so it is nice to have a selection on hand. Have not abused them to determine if they are durable, but they seem fine!

As advertised and we didn’t get screwed
