PSA: Stop guessing on concrete anchor spacing. The chart is right there.
I spent years just eyeballing spacing on wedge anchors for metal stud framing, thinking I was saving time. Then a structural inspector flagged a whole row on a Walgreens build in Phoenix because I was 3 inches off the pattern. Has anyone else found that the manufacturer's technical guide actually makes installation faster once you stop ignoring it?

I read somewhere that a lot of those inspector flagging issues come down to them measuring from the wrong reference point on the anchor itself. Like they're supposed to be measuring from the center of the anchor not the edge or something. I saw a structural engineer's blog once that said skipping the chart is the number one reason for pull tests failing on those Walgreens type builds. Once I started actually using the manufacturer's chart on a job, I realized it even had a note about minimum edge distance for different concrete strengths which I never would have guessed. It only added like 2 minutes to my layout but saved me from having to redo a whole row of anchors later. The chart really does make things faster when you stop treating it like optional reading.
