Muy funcionales, recomendable

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

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.

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!
