Super handy to have laying around
Bought these to have laying around and for one specific size to use on some rubber bump stops. Then just today I needed a nut for something and it was in this box. It was such a relief to have it right there instead of having to drive to the store or wait for delivery. Extra washers, bolts and nuts are always nice to have handy.

Wrench and heads strip easily
It is very easy to round off the allen wrench that came with the kit or strip the hex hole in the heads. I tried a better allen wrench and it just stripped the hex hole. I ruined a few screws before I was able to get four to work on my project. You have to be very careful when screwing these in.

Good stainless hardware, but nut diameter and case could be better
The stainless steel hardware itself is legit. The bolts are very nice quality, and I appreciate that the set includes washers and an Allen hex wrench. However, I was disappointed with the nuts. The outer diameter is extremely small and doesn’t fit properly in standard recessed areas that are designed for nuts. In many common applications, they’re simply too small to work as expected. Another downside is the case. It cracks very easily and doesn’t feel very durable. I wish the storage case was made from a stronger material.
