How to Fix a Broken Interior Wall Anchor: Step-by-Step Guide

Frequently Asked Questions

Why do drywall anchors fail?

Anchors fail when they are overloaded beyond their rated capacity, when they are installed in drywall that is too thin or damaged, when the wrong anchor type is chosen for the application, or when the drywall around the anchor crumbles from repeated stress or moisture exposure.

How do I remove a plastic expansion anchor that is stuck in the wall?

Push the anchor fully into the wall cavity using a nail set or screwdriver — it will fall behind the drywall. Then fill the resulting hole with lightweight spackle. Alternatively, use pliers to rotate the anchor counter-clockwise while pulling it out, though this often enlarges the hole.

What is the strongest type of drywall anchor?

Toggle bolt anchors (also called butterfly or snap toggles) are among the strongest, capable of holding 50 to 100+ pounds in drywall. Metal self-drilling toggle anchors (like E-Z Ancor Toggles) are a good middle ground of strength and easy installation.

Can I patch a large anchor hole and re-anchor in the same spot?

For small anchor holes (under 1/2 inch), spackle the hole, let it dry fully, sand smooth, and re-anchor nearby but not in the same spot. For larger holes, use a drywall patch kit, then anchor into an area with solid drywall at least 2 inches from the patch.

How do I find a stud if my anchor keeps failing?

Use a magnetic or electronic stud finder to locate studs, which are typically 16 inches apart on center. Screwing directly into a stud with a 2.5-inch or longer wood screw gives you the strongest possible hold and eliminates the need for a wall anchor entirely.

Are self-drilling drywall anchors reliable for heavy items?

Self-drilling plastic anchors are convenient for lightweight items up to about 20 pounds. For anything heavier — TVs, large mirrors, shelving with significant loads — use toggle bolts or locate a stud. Never use plastic expansion anchors for items that could cause injury if they fall.

Fixing failed wall anchors: (1) Plastic expansion anchor spinning in hole (most common failure): these anchors are not load-rated for significant weight. Replace with a toggle bolt or SNAPTOGGLE anchor.

Wall anchors are a convenient solution when you cannot hit a stud, but a failed anchor leaves behind a damaged hole and a frustrating problem. Whether your anchor pulled out, spun in place, or crumbled the surrounding drywall, fixing it correctly takes less time than you might expect — and choosing the right replacement anchor the second time makes all the difference.

Understand Why the Anchor Failed

Before reaching for a replacement, figure out what went wrong:

• Overloaded anchor — the item being hung exceeded the anchor’s weight rating
• Wrong anchor type — plastic expansion anchors often fail in thin or hollow walls; they need solid drywall at least 1/2 inch thick
• Damaged drywall — moisture, repeated drilling, or over-driving the screw can crumble the gypsum core around the anchor
• No anchor needed — many people use anchors even when a stud is within easy reach

Knowing the cause helps you avoid repeating it.

Tools and Materials

• Nail set or old screwdriver (to push in the old anchor)
• Needle-nose pliers (to pull out stubborn anchors)
• Lightweight spackle or drywall joint compound
• Putty knife
• Fine-grit sandpaper (120-grit)
• Replacement anchors appropriate for the load
• Stud finder

A stud finder is the most valuable tool for this job — finding a stud entirely eliminates the need for an anchor and gives you the strongest possible mounting point.

Step 1: Remove the Old Anchor

For plastic expansion anchors: Hold a screwdriver against the face of the anchor and tap it firmly with a hammer to push it flush with the wall, then keep tapping until it falls into the wall cavity. The small hole left behind can be filled and the anchor is out of the way.

For metal toggle bolt anchors: Remove the bolt (the wings will drop inside the wall), then either push the barrel in or use needle-nose pliers to rotate it out.

For self-drilling metal anchors: Insert the screw back into the anchor, then use a screwdriver to back it out counter-clockwise. These often come out intact.

Do not try to pry plastic anchors out from the front — you will almost always make the hole larger and damage the surrounding drywall.

Step 2: Fill and Repair the Hole

For holes up to 3/8 inch, lightweight spackling compound is ideal. Apply it with a putty knife, slightly overfilling the hole, then scrape it flat. It dries in 1–2 hours and can be lightly sanded flush once dry.

For holes larger than 1/2 inch — usually created when an anchor tears out a chunk of drywall — use a drywall hole repair patch kit. These self-adhesive mesh patches stabilize the opening so joint compound has something to grip. Apply two thin coats of compound, sanding between coats.

Allow all repairs to dry completely before re-anchoring. Wet joint compound will not hold an anchor.

Step 3: Choose the Right Replacement Anchor

Match the anchor to the job:

• 0–20 lbs (small frames, lightweight shelves): Self-drilling plastic anchors or threaded drywall anchors work fine
• 20–50 lbs (medium mirrors, medium shelves): Metal self-drilling toggle anchors (E-Z Ancor style) or Snaptoggle-style anchors
• 50+ lbs (TVs, large shelving, heavy artwork): Toggler snap toggle bolts or — best of all — screw directly into a stud

Always check the anchor’s rated load on the package and stay well under the maximum.

Step 4: Install the New Anchor Correctly

Drill or drive the anchor at the correct size for the product. Drive self-drilling anchors until the head sits flush with the drywall surface — do not countersink them, as this weakens the hold. Thread the screw into the anchor snugly, but avoid over-tightening, which compresses the drywall face and reduces holding strength.

For toggle bolts, drill the specified hole size, insert the toggle through the wall, and tighten the bolt until the toggle seats firmly against the back of the drywall. You will feel the resistance increase as the wings spread behind the wall.

Step 5: Test Before Loading

Before hanging anything, press firmly on the anchor with your palm and twist the screw gently. A properly set anchor should feel completely solid. If it wobbles or spins, remove it, fill the hole, and start fresh in a slightly different spot using a heavier-duty anchor type.

Toggler brand snap toggle bolts are a reliable upgrade from standard anchors and can stay in the wall permanently, allowing you to remove and replace screws multiple times without the anchor shifting.
