    Decent hardware - part II
  

*by S***B on Reviewed in the United States on August 1, 2023*

I am constantly building things, tinkering and fixing things. With that said, most things anymore use metric hardware and I definitely needed some for what I do. This collection of hardware fit the bill!The set contained almost all of the sizes I typically use. The best part is it contained not only the screws, but all of the supporting hardware as well. The bonus metric hex wrenches is a nice touch in case you don't have these in your tool box. Add to all that, everything is in a tidy storage case that allows you to keep everything organized and easy to find.Now the downside. This isn't high quality precision hardware, but it works just the same. If you are looking for precision, then go pay about 4-5 times the price. The other downside to this is all of the hardware is covered with an oily substance presumably to prevent it from rusting. Be prepared to get it all over your hands and wipe everything down before you use it.For general purpose hardware, this stuff works fine and this is the second pack of hardware I purchased from this vendor. I'm happy with it and I'm sure you will be too.

    Good product
  

*by K***Z on Reviewed in the United States on February 13, 2023*

Completely satisfied.  The pieces in each compartment were in a resealable bag.  I thought that was a good idea with such small screws and nuts.

Ha comprado pernos M3 de varias marcas y este es el de mejor calidad, tal cual como anuncian. Falta que tengan pernos con otras formas de cabeza.
