Drop-in anchors only work when the hole depth, hole size, cleaning, and setting match the manufacturer direction. A bad set can look fine until it is loaded.
Ask before moving anchors, changing spacing, deleting supports, drilling structure, or altering trapeze/seismic layout.
Watch out
Do not set anchors in unknown or unapproved substrate.
Check
Check the anchor manufacturer instructions for the required hole diameter and embed depth for the anchor being used.
Use the correct bit size and mark the intended drilling depth on the bit before drilling.
Clean dust and debris from the hole before setting the anchor.
Set the anchor with the correct setting tool until it is fully set per the manufacturer direction.
If an anchor feels wrong, does not set right, or spins, do not load it. Mark the location and get direction before using it.

Say this to your foreman
I may have a drop-in anchor that did not set correctly at [location]. The setting tool did not feel right / the anchor may not be fully set. Do you want me to pull it, drill adjacent, or leave it marked for review?
