10 Steps on How to Remove Hammer Drive Concrete Anchors

Step 1: Protective Wear

Put on safety glasses to protect your eyes. Also, wear gloves to protect your hands from any sharp edges or surfaces. Always wear protective clothing when dealing with power tools. Also, make sure the work area is well-ventilated.

Step 2: Get a Grip

Using a pair of pliers or an adjustable wrench, get a good grip on the head of the anchor bolt. If it is too tight to turn by hand, use a vice for extra leverage. Keep in mind that the head of the bolt can be quite sharp, so use caution when gripping it.

Step 3: Drill Holes

Using a power drill and masonry bit, carefully drill a hole in either side of the anchor bolt. The hole should be slightly wider than the diameter of the bolt to allow for easy removal. Drilling on either side of the bolt helps to weaken it and make it easier to remove.

Step 4: Chisel Away

Using a cold chisel and hammer, carefully chip away at the concrete around the anchor bolt head until there is enough space for the bolt to be removed. Be sure to use caution when using this tool, as hitting the bolt too hard can cause it to shear off.

Step 5: Grinding

Using a grinder, carefully grind away any remaining concrete around the bolt head that is preventing removal. Keep in mind that you may need to use a larger grinding wheel if the bolt head is especially stubborn or embedded in hard concrete. Be sure to wear safety glasses to protect your eyes from flying debris.

Step 6: Loosen the Anchor

Using a wrench, loosen the anchor bolt by turning it counterclockwise until it is loose enough to be removed. If the bolt does not turn easily, you can use a hammer to tap on the head of the bolt, which may help loosen it.

Step 7: Remove the Anchor

Once the anchor bolt is loose enough, it can be pulled out of the hole with pliers or a pair of vise grips. If necessary, you may need to use a hammer to help pry the bolt from its embedded position.

Step 8: Clean Up 

Using a broom and dustpan, clean up any debris that may have been left behind by the removal of the anchor bolt. Be sure to dispose of any broken pieces properly.

Step 9: Look for Damage

Inspect the area around where the anchor bolt was removed to make sure there are no signs of damage or weakening in the concrete. If any damage is observed, it should be addressed before continuing with the project.
