Concrete screws vs Lag Bolt/Shield Anchors - is one better?
I see that you recommend and sell GRK Caliburn pan-head concrete screws for installing Titan post anchors on concrete. I was wondering how these concrete screws compare to using a typical lag bolt & lag shield anchor? Does one method offer advantages over the other?
I’m installing a 42” high railing on my raised concrete porch and am planning on using four fasteners per Titan post anchor (4x4). I’m interested in maximizing holding power, ease of installation, and having the ability to remove and refasten the posts in the future.
While GRK’s website alludes to the ability to remove and replace their screws, should I expect a reduction in holding power over time with reinstalled screws? Would a lag shield anchor work better in this regard?
Would either fastener provided better pull out strength when installed in seasoned concrete or would they be roughly equal? Thanks for your help.
BTW, I love the Titan post anchors. Sharp looking, easy setup and strong! Nice product.
