I sometimes use it to install screws that feel like don't fit the driver well. That way I don't leave a trap for the next guy. There is a product called screw grap on the market, buts its really just grinding compound.
Hi Bill, do you think you could either expand your subject a little or a photo.
I think that there is a transatlantic term difference here. Are tou talking about a slotted head screw or a hex head screw like a bolt, perhaps I am just being a little dim this morning, but it sounds very interesting and I would like to get to the base line, Thanks Pat
