    Q:What size anchor bolt to use with the APB44?
    by|Aug 29, 2023
    1 Answer
    Answer This Question

    A:  Hi Donald, this is Colin from Simpson Strong-Tie. The APB44 requires one 5/8" diameter anchor. A design professional must determine the anchor bolt type, length, and embedment. Our Titen HD Mechanically Galvanized Screw anchors and SET-3G epoxy adhesive are some of the retrofit anchor options. Please refer to our website at www.strongtie.com for more information on those products. Or if you would like to speak with a member of our Customer Service team, please call us at 800-999-5099. Thank You.

      Q:What size of anchor and bolt to use on the 4x4 base with the concrete being 3 in thick?
      by|Aug 24, 2023
      1 Answer
      Answer This Question

      A:  ER91, this is McKenzie from Simpson Strongtie. The APB44 calls out for (1) 5/8" anchor bolt, we have a tech bulletin you can look at on our Strongtie.com website, (TEB-PSTB23). Ultimately the type and length would be per designer or engineer of record. Thanks.

          Not true 6x6
          We bought true 6x6 posts. This does not fit those. No where on the packaging does it say this
