Soft steel - Hex strips easy tightening down

Very soft steel. The hex head strips easily when trying to tighten. They were going into abs plastic that I needed a tight fit. Had to drill two of them out. Don't waste your money.

Pros

The black oxide finish on these screws not only adds an appealing, professional look but also offers corrosion resistance. This makes them highly versatile as they can be used in a wide range of applications, both indoors and outdoors. Additionally, the flat head design adds a sleek and modern touch to any project they are used in

Cons

Despite the black oxide finish, the steel material of this screw may still be prone to rusting. This means that it may not be suitable for use in environments with high moisture or humidity levels, leading to a shorter lifespan and potential failure of the product over time
