Great product
Installed the plugs on the water pump and intake manifold to block off un-needed ports. Had to really wrap them with a few layers of tape to keep them from leaking but afterwards, worked flawlessly.

Requires very large hex wrench for larger plugs.
They appear to be good quality, but the larger plugs require a bigger hex wrench than most diy people have.

As per description
I utilize various pipe plugs for an engine I am working on. I found the aluminum plugs very soft and possibly unable to get them back out without stripping the hex The brass plugs seem to go deeper into the same hole as the steel plugs. So where I have to go shallow I use the steel plugs otherwise the brass. I will not use the aluminum as it was very hard getting back out after checking fitment, I rounded the hex. Hope this helps.

secondary uses
I purchased this to use in a car build. however they did not work, not because they were wrong size or poorly made, more of the vehicle being extra picky. I did find a good use for them though. I installed a internal threaded brass nipple on my bong and used one of the plugs to close it when not using it so the water doesn't get spilled. good for other uses Im sure I will find here soon.
