Should I have been using drill/driver to drive them in


I only wanted to drive in 2 screws but in this example I used 7 screws


Two of the heads that you can see spin freely so I assume they have snapped as well.
It may be may application of these so if I'm mis-using them please let me know but, and I know these have been recommended by the site, for me they were quite poor. If I ever do something like this again I will try spax.
