A drop-in anchor hole was drilled too shallow
A drop-in anchor must sit fully in the drilled hole before it can be set correctly. If it sticks proud or bottoms out, redrill/clean the hole before loading it.
Stop if
- If that anchor sticks out past the concrete face, it's a structural failure waiting to drop. Drill your holes a quarter-inch deeper than the shield, blow the dust out, and make sure that anchor sits completely flush before you strike it.
Watch out
- Do not thread rod into an anchor that was never fully seated or set.
Check
- Compare hole depth to the anchor and approved attachment detail.
- Blow/clean dust from the hole.
- Make sure the anchor sits flush/recessed as required.
- Use the correct setting tool.
- Do not hang duct until the anchor is properly set and checked.
