TOTFSTNR 230Pcs Socket Set Screws Assortment Kit, M2 M3 M4 M5 M6 M8 Grub Screws with Hexagon Socket, Hex Allen Head Screw Set Kit for Door Handles, Light Fixture (Metric)

I purchased these to replace the set screws on my back flow preventers. The next time I need to replace leaking back flow preventers it will be a much easier job. The quality of the set screws looks really good and they work perfectly for my project. The pack even included the Allen wrenches in appropriate sizes. The case they come in keeps them secure and separated by size. The set is a great add to my tool chest.

The multiple sizes of screws or my door handles made my life a lot easier.

This did the job. The only suggestion I have is that they provide a place within the storage case for three hex wrenches that fortunately come with it.

They are set screws. They set things and they do it well. They are in teeny tiny bags organized by size in compartments identifying them by size. It is much easier than getting a micrometer and measuring them.

Compact storage of set screws and Allen wrenches. Hard to find at stores sizes included with tool to install.
