    Q:Why can't lag bolts be used in large, middle holes referred to as pilot holes?
    by|Apr 30, 2019
    2 Answers
    Answer This Question

    A:  The question is,how is this going to be used. This is meant for vertical support anchored into concrete. You would use a lag bolt to anchor into wood. This was not made to be anchored into wood. A lag would not give any structural integrity. This is not meant to be used to attach a 4x4 to another wood base structure with a lag. A lag is a poor support. This is meant to be bolted over a threaded rod embedded deep into concrete where it sits just above the nut and rod end or is counter-sunk into the 4x4 with a sealant. Only then is it lag bolted from the side holes or a thru- bolt is used.

    by|Jan 6, 2023

      A:  I can't think of any reason why one COULDN'T use the large holes for lag bolts. Since these post anchors are only thin sheet steel, the lag bolts are probably overkill and may risk splitting the base of the post unless a pilot hole is drilled, There will be ample strength if you use six #10 x 1.5" screws in the small holes provided for this purpose. This will, probably, provide better distribution of loads in both the post anchors and wood.

      Answer This Question

      A:  Yes. these will secure the posts to the deck but you will need some lateral bracing. These anchors are far too flexible to keep a post vertical by themselves and any substantial lateral pressure at the top of the post will cause them to bend.

      A:  Well, You say low to the ground. So are the post being bolted to a wood deck or to a concrete pad or other poured structure. If concrete, yes, you could use one at each base, but you will have visible bolts showing and the center bottom hole is for a bolt that should have been part of the re-bar installed/tied in before the pour. Otherwise you will have to drill a hole and install an anchor system of your choice to bolt it in place. Now you can end the post above that anchor bolt or counter sink a hole in the end of the post to straddle the bolt using some type of waterproof sealant. The half- base itself should be painted with a quality epoxy paint or it will rust over time. If you end the post just above the anchor bolt, you still need some type of sealant applied to the entire base section that is in contact with what ever surface you are bolting to. You can always frame it in to hide the base, but it still needs to be painted and coated with something like blind roof nailing compound or Por-15 paint. I assume you will be using wolmanized lumber. Good luck.

        A:  This is what you would use to anchor the post to concrete. Keep shopping for a better choice. There should be better choices out there. You could screw it into place via a Kreg system and use the wood plugs to cover the screws and then build a simple but decorative base frame around the 4 x 4.

          Wonderful product. However Home Depot had them at one price on their website and I paid almost $2.00 more for each one which cost me $25.00 more that I wasn't prepared for. P
