I installed several deck ledger boards to my 6" deep poured concrete foundation. I am pleased with the ease and outcome.

The product is hearty works as advertised in the numerous videos in which the products appear. I elected to experiment by installing a few of the Titen HD screws using a old school 3/4" drive ratchet and socket. As one might imagine it took some effort. The rest I installed with an impact driver. The latter was effortless. Both set in place equally well and seem to offer the connection I was looking for. The impact driver makes the installation easier but it is not necessary.

Worked as expected, works with standard 1/2" masonry bit.
