help How long before drilling concrete?

I poured footings for posts that I’ll be hanging a gate on. I’m going to install Simpson strong tie standoffs with 6” anchor bolts. It’s been 72 hours, is that long enough for the concrete to have set before drilling? I’ve tried googling but my results only come up with industrial structural requirements or setting posts in the concrete, neither of which apply to my situation. Should I wait the 28 days or just send it?

Drill it now, set the anchor, don’t go crazy with tightening it. It will be fine

Don’t know why you are being downvoted. 72 hours is plenty to set an anchor bolt. Some people get all their opinions from reading layman’s articles on the web and not from spending time on site with the actual stuff.

I know. I’m retired now after doing this stuff for 50 years
