Review on OZCO 56627 4 Inch Timber Screws by Mike Abu

Based on our own experience, these industrial and scientific screws are a complete waste of money .We purchased THEM for a big project and were severely disappointed. The pros of these screws are almost non-existent, except for the fact that they come in a big pack. However, the cons are numerous - they are difficult to screw in, constantly stripped, and break easily. We had to resort to using different screws halfway through the project. Save yourself the hassle and pick a different brand..
