How much deeper than the anchor being installed should the hole be drilled?

Drilling the hole 1/4" to 1/2" deeper than the anchor being installed is important as it allows for proper installation and ensures that the anchor is securely fastened within the material. This additional depth accommodates any debris or dust that may accumulate at the bottom of the hole during the drilling process, ensuring that the anchor can fully seat and engage in the material. Additionally, this depth helps to provide a margin for error during installation, ensuring that the anchor is not sitting flush with the surface, which could compromise its holding strength and performance. This practice enhances the overall stability and reliability of the anchor in use.
