How to Remove Concrete Anchors: Every Type, Every Method

Removing a concrete anchor without damaging the surrounding concrete takes the right tool and technique. Some anchors come out cleanly; others need to be cut flush or driven deeper. Here is exactly how to remove every common anchor type.

Can All Concrete Anchors Be Removed?

The short answer is no. Anchor removability depends entirely on the anchor type:

Anchor Type	Removable?	Method
Tapcon Screw	Yes — easily	Unscrew with correct driver bit
Plastic Plug	Yes	Pull out with pliers after removing screw
Sleeve Anchor	Partial — cut flush	Cut bolt flush with angle grinder or hacksaw
Wedge Anchor	No — drive deeper or cut	Drive flush with hammer or cut with grinder
Drop-In Anchor	No — drill out	Drill out with larger carbide bit
Epoxy Anchor	No — cut flush only	Cut rod flush with grinder

How to Remove Tapcon Screws

Tapcon screws are the easiest concrete anchor to remove. Use a drill or impact driver with the correct bit — #2 Phillips for most standard Tapcons, or a hex bit for hex-head Tapcons. Set the drill to reverse and apply firm pressure while turning. Drive slowly — rushing strips the head.

If the head is stripped, use a screw extractor or cut a new slot with an oscillating tool and use a flathead driver. If the Tapcon breaks off below the surface, use a carbide bit to drill it out or simply leave it and drill a new hole nearby.

How to Remove Wedge Anchors

Wedge anchors are designed to be permanent — the expansion wedge locks harder as tension increases, making them nearly impossible to pull out intact. You have three options:

Option 1: Drive it deeper (best option)

Remove the nut and washer. Place a punch or old bolt on the threaded end and drive the anchor down with a hammer until the top is flush with or below the concrete surface. Fill the hole with hydraulic cement or epoxy filler. This is the cleanest solution when you need a flat surface.

Option 2: Cut it flush

Use an angle grinder with a metal cutting disc to cut the bolt as close to the concrete surface as possible. Then use a cold chisel and hammer to drive the remaining stub below the surface. Grind smooth.

Option 3: Use a bolt extractor (rarely works)

Bolt extractors grip the outside of the bolt and turn it counterclockwise. They rarely work on wedge anchors because the expansion mechanism resists rotation. Only worth trying if the anchor is loose or partially failed.

How to Remove Sleeve Anchors

Sleeve anchors cannot be removed intact — the sleeve expands against the concrete and cannot be compressed once set. Your options:

• Cut flush: Use an angle grinder or oscillating tool to cut the bolt head off flush with the surface. The sleeve body remains in the hole but is flush with the concrete.
• Drive deeper: Remove the nut, place a punch on the bolt end, and drive the whole anchor deeper into the hole with a hammer. Fill the void above with concrete filler.

How to Remove Drop-In Anchors

Drop-in anchors are the hardest to remove because the anchor body expands inside a blind hole with nothing protruding above the surface. Options:

• Drill out: Use a carbide masonry bit one size larger than the anchor diameter to drill out the anchor body. A 3/8" drop-in anchor (which uses a 1/2" hole) can be drilled out with a 5/8" carbide bit.
• Leave it: If the hole location isn't critical, simply fill the threaded socket with epoxy filler and move on.

Reusing Holes After Anchor Removal

After removing an anchor, the question is whether the original hole can be reused. Generally:

• Tapcon holes: Can be reused with a slightly larger Tapcon (next size up) if the original threads are damaged.
• Expansion anchor holes: Do not reuse for expansion anchors — the hole is enlarged and the expansion mechanism won't grip properly. Use epoxy anchors in existing holes, or drill a new hole at least 3 anchor diameters away.
• Damaged concrete: If the concrete crumbled or cracked during removal, consult a structural engineer before installing replacement anchors nearby.

Frequently Asked Questions

Can you reuse a concrete anchor hole?

For Tapcon screws, yes — use the next size up if threads are worn. For expansion anchors (wedge, sleeve), do not reuse the same hole for expansion anchors. The hole is oversized and the expansion mechanism will not develop adequate grip. Use an epoxy anchor in the existing hole, or drill a new hole at least 3 anchor diameters away from the old one.

How do you remove a broken Tapcon screw from concrete?

If the Tapcon broke at or above the surface, use a screw extractor or cut a new slot with an oscillating multi-tool and use a flathead driver. If it broke below the surface, use a carbide masonry bit to drill it out — start with a small pilot bit and work up to the full anchor diameter. Alternatively, fill the hole with epoxy and drill a new hole nearby.

What is the easiest concrete anchor to remove?

Tapcon concrete screws are by far the easiest — they unscrew with a standard driver bit just like a wood screw. This is one of the main advantages of Tapcons over expansion anchors for applications where future removal is possible. If you think you might ever need to remove an anchor, always choose Tapcons over wedge or sleeve anchors.

How do you fill concrete anchor holes after removal?

For small holes (under 1/2" diameter): use hydraulic cement, anchoring cement, or two-part epoxy filler. For larger holes or holes in structural concrete: use non-shrink grout. Clean the hole thoroughly before filling — dust and debris prevent proper bonding. Allow full cure time before applying any load to the repaired area.
