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

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!

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!!!

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 have been trying to find replacements for mountain bike water bottle cage screws. They are typically M5 x 12 to 20 mm socket head cap screws but the catch is they are stainless steel and smooth, polished heads not knurled. Amazon has multiple different replacements specifically marketed for that purpose but they all have fatal flaws. Most of them have too small of diameter heads making it necessary to use washers or the heads pop through the cage holes. Others are poor quality and have pitting and other surface imperfections or are not really stainless steel (Amazon has become the wild west will all kinds of false claims made by sellers, especially overseas sellers). Wolf Tooth components makes nice screws but they have tapered heads, are titanium (making it very likely you will get galvanic corrosion on aluminum or steel frames due to the dissimilarity of the metals) and are $15 for 4 bolts. I originally bought those thinking they were make in the USA but based on the labeling on the bag they are imported so why would you pay more?Finally I found these. They are nicely polished, have the same size heads as OEM bike screws and you get a lot of them for about $13. They are only slightly magnetic meaning they probably really are 304 SS (304 SS is not magnetic in it's pure form but forging, polishing and other activities induce weak magnetism). My only complaint really is that they are made in China. I would gladly spend more for made in USA.

Good kit to have on hand

Got these for the himiway Zebra.

I'm a Professional Bike Mechanic and is always good to have an assorted metric bolts selection at hand, I have doubts about this being real Stainless Steel for the price, but the magnet dont lie. awesome selcction on sizes at a fraction of the price of wat they cost at your local home store.

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.
