Hilitchi 510pcs M3 M4 M5 Stainless Steel Hex Socket Head Cap Bolts Screws Nuts Assortment Kit - 304 Stainless Steel (Hex Socket)

A very nice assortment of fasteners in a nice sturdy case with great latches to keep everything in place. A great value for such a quality product. Highly recommended and would purchase again if needed. Received it fast as well. I used two lengths of the M4 screws for M/C carburetor float bowl replacements as they tend to need to be drilled out occasionally because of some people using the incorrect type of Phillips head screw driver, consequently mangling up the head of screw to the point of leaving drilling as the only option for removal prior to being rebuilt. But in all fairness to those people, a Jato head screw driver made for these carb. screws are very hard to find, if not impossible. Thanks!!!

I use these screw on my 3D printers. The screws are well finished and plenty strong for my purposes. The assortment was varied enough to meet almost all my needs. As others have stated the container is the weak point. My box had been broken at one corner and some nuts and a few screws had fallen out of a hole in the shipping envelope. I contacted the vendor and they immediately made good on it, sending replacements for the missing screws and a new box. I hot glued the partitions in place as they tend to lift up and let the hardware mix. I would but this again.

For this price, I was expecting to get an assortment of bolts and nuts that were about 80% trash and 20% usable. Much to my surprise, I have not encountered a single unusable piece. I've used more bolts than nuts, however, everything has been fine. I will say that the hex socket in the cap of each boltis not perfectly centered in the head and while I'm fairly OCD about things like this, it is not bad enough to keep me from using these, even in applications where the bolt will be visible. The fact I'm OCD about this detail may be the only reason I even noticed in the first place. As has been mentioned, the plastic container is indeed trash, thus my four star rating. Considering the price though, I would have rated it 4.5 stars if I had the option. It arrived cracked and some of the bolts and nuts had mixed and were no longer separated. I used it for a week or two and the condition worsened, with most of the smaller units mixing better than they would have if I'd tried to mix them together by hand. I spent 10 minutes re-sorting everything and slotted them all into other containers that I already had on hand. I honestly would rather they just shipped everything mixed together in a cardboard box that I could have actually recycled. Note I am not using these outdoors, on vehicles, on the farm, etc. I'm using them for indoor science projects, 3D printers, electronics, etc. For these applications, they are sturdy and I have had no issues.

I bought these to have bike bottle cage screws and just a few sizes of metric screws around. I love that the container they come in has a thick rubber gasket to make sure none slip out of the box, and the screws are of good quality it seems. The dividers to organize the screws are not that great like most of the ones done like this. But I would order these again if I needed more!

This is an excellent buy for ebike owners. I have used several sized screws and bolts out of this pack and they just work. I used them on bike back rack, rear and front basket, passenger seat with handle, and, front light on second ebike. Used them on a bike bell for the kids. I bought them to use on my Wildeway FW11 3.0 ebike and they have paid for themselves by being useful when needed. They work with the kids bikes non electric and for our electric bikes.

I recently inherited an E-Bike from my father and it came with a number of missing fasteners (Hex head cap screws). This kit was perfect as it came with every size that I needed to attach various bike accessories. And the fact that everything is stainless steel means that I don't to worry about them rusting when things inevitably get wet.

I ordered this expecting to have to do some sorting based on the reviews, but when I opened the package I was pleasantly surprised to see that everything was intact. While it's not the highest quality, the case is not nearly as cheaply made as I was expecting, and I plan to continue using it. (And even if it had arrived broken, I don't think it's fair to give the product a bad review because of careless postal workers.) All in all these look good, I haven't had any problems with bad threads or stripping yet, and they're cheap.

Good kit to have on hand

Delivery was quick, parts are well labelled and quality is really good.

I made the rookie mistake of tightening my limit screws on my front derailleur while under load and to make a long story short, 1st don't tighten limit screws with any form of resistance, 2nd Amazon has you covered if you do, these worked flawlessly for my shimano altus limit screws and as a bonus you get extra bolts for any open threads on your bike from water bottle cages to rear rack mounts these have you covered. I will update if the screws begin to show signs of rust or anything but as is they are doing what I need!

Muy funcionales, recomendable

very happy.. the only one thing i would have in this kit are the flat washers!!

No complaints here!
