Q:are the screw holes supposed to be oriented any specific way? For instance, facing towards/away from house? Or side to side?
by|Nov 23, 2023
1 Answer
Answer This Question

A:  ​Hi DeckBuilder, thank you for your message. The direction of the fasteners has no relation to strength, this is purely an aesthetic preference on which way to orient the post base. If you need more information or have additional questions, please contact the Simpson Strong-Tie Customer Service team at 800-999-5099. We look forward to hearing from you! - Stacy

            Good Anchor Ties, but not the Best
            Mounts easily, but not the sturdiest base anchor tie for a larger arbor. Had to brace top of 4 arbor corners to keep the light sway down. Originally purchased 4 other stronger Simpson Strong Ties, but they were too big at the base to anchor to an 8” diameter concrete post. I guess I could have bought a 10” Auger bit, but couldn’t justify the 1 time use for over $100.00.

            Standoff is sturdy, no issues with its strength. Be aware that these fit nominal 6X6 (5.5" X 5.5") posts like a glove. Maybe not the most visually pleasing compared to decorative standoffs, but substantially lower in price. Plan to cover standoff with custom trim at a later date.

              Secure base for railing post
              I used these to secure the handrail post for my porch to a concrete pad at the base of the stairs. Set in place with threaded rod and epoxy into a drilled hole, and this holds the post securely. Added some structural screw side connectors for additional security

                Good post base
                I intalled this post base onto a retaining wall. The top of the wall was filled with concrete so I used a Simpson Strong Tie to secure the post base into the concrete.

                  The bracket securely holds a 6 x 6 post about 1" above the concrete support pier. This will extend the life of the wood post by holding it out of contact with the concrete and any water accumulation. In my area, municipal inspectors are requiring this method of post installation as opposed to a buried and set in concrete installation. I recently had to retrofit 3 posts that had rotted at ground level due to that method of installation 20 years ago.

                    Easy to use, holds your beam about one inch off the ground and keeps the beam in place.
