Review on Grip Rite Prime Guard P158STB5 by Darrin Parasson

They exceeded my expectations. I drive 560 of them on white oak. I haven't had any significant problems. Even using an impact wrench none of them broke. None of the heads broke off. I tapped the hammer a little before crashing into the pine deck and oak beams. About 10 gates lost some of their paint from the impact. (I can't blame the manufacturer. These are screws, not nails.) The only small point of criticism: In my opinion, there should have been 2 bits for the number of screws. The included bit went through about 250 screws. If it were possible I would give the product 4.5 stars.
