How to Use Drywall Anchors

Drywall anchors are fastening tools used to mount objects onto walls that do not have wooden studs directly behind them. Since drywall alone cannot hold screws securely, these anchors distribute weight and provide a firm grip inside the wall material, ensuring your items stay put.

Step-by-Step Instructions for Using Drywall Anchors

Step 1: Mark the Spot

Identify and mark where the anchor needs to go.

Step 2: Drill the Hole (if required)

Depending on the anchor type, you might need a drill. For toggle bolts and molly bolts, pre-drill a hole slightly smaller than the anchor.

Step 3: Insert the Anchor

Push or tap the anchor into the wall until it’s flush. For self-drilling anchors, twist them in with a screwdriver.

Step 4: Insert the Screw

Drive the screw into the anchor until it’s tight, but avoid over-tightening which can weaken the anchor.

Step 5: Test the Stability

Gently pull or hang the item to check if it’s secure. If there’s movement, reassess and reinstall.

How to Use Different Types of Anchors

Installing Toggle Bolts

• Drill a hole large enough for folded wings
  
• Insert the bolt with wings folded
  
• Tighten while holding the fixture in place

Installing Threaded Anchors

• Twist anchor directly into drywall
• Screw in the fastener through the item you’re mounting
  

Installing Self-Drilling Anchors

• Use a screwdriver to drill the anchor directly
  
• Insert screw and tighten

Installing Molly Bolts

• Insert into pre-drilled hole
  
• Tighten screw to expand anchor
  
• Remove screw, mount item, then reinsert screw

Q1: Can I reuse a drywall anchor?
A: Generally no. Once removed, anchors lose grip and shouldn’t be reused.

Q2: How much weight can drywall anchors hold?
A: It varies. Light-duty anchors hold 10–25 lbs, while toggle bolts can handle 100+ lbs.

Q3: Are drywall anchors safe for ceiling installations?
A: No, unless specified for ceiling use. Use ceiling-specific toggle bolts or mounts.

Q4: Should I use drywall anchors if there’s a stud?
A: No. Use wood screws directly into the stud for better support.

Q5: How far apart should I space drywall anchors?
A: At least 2–3 inches apart to avoid compromising wall strength.

Q6: Do I need a drill for self-drilling anchors?
A: No. A screwdriver is usually sufficient.

Drywall anchors are a reliable and affordable way to mount various items securely, even without a stud behind the wall.
