Why: The extra depth of the hole will ensure that the anchor does not bottom out and will allow space for dust from the drilling process.
How deep should anchor bolts be in concrete?
Steps to Installing Concrete Fasteners The hole should be drilled 1/4″ to 1/2″ deeper into the base material than the anchor will penetrate. This allows for any material to fall when the anchor is inserted into the hole. After the hole is drilled, it must be cleaned of all debris, material or dust.
Why are my drywall anchors pulling out?
