The hex on the driver bits included with the Deckmate screws seems to have a undersize hex. I used these in building a shed where I didnt want rusty screws. I use a magnetic bit holder to retain the screws on the bit but the holder is retaining the bits instead. After driving a few screws the bit has twisted out of position in the holder and I can not pull it out. I now have two bit holders with these special bits permantly embedded. I suppose I could try torching them out. Any feedback on this? Has anyone else experienced this?
