Go to fastner for concrete
01/10/2019 by Steven P. (United States)
“Always used the 3" version, but bought 4" so when I'm attaching to questionable surfaces (limestone foundations...) have the extra inch of engagement to find solid material. Great product. Use when ever I need to attach anything to concrete, brick, stone... I've used a variety or products in the past and this is the fastest and easiest way to attach to concrete. Once it's driven in it's permanent. Great price and service from concrete fastening.”
