The Best Wall Anchors for Heavy TVs (And When to Use Each)

The most common mistake in DIY TV mounting isn't picking the wrong mount — it's using the wrong anchor. A TV mount is only as strong as what's holding it to the wall. When studs aren't available or the mount's hole pattern doesn't line up perfectly with your studs, you need the right anchor for the job.

Here's a breakdown of the main anchor types, their weight ratings, and when to use each.

Option 1: Lag Bolts Into Studs (Best Option)

If you can align your mount with two studs, this is always the right choice. 3" lag bolts (also called lag screws) driven directly into the wooden stud are extraordinarily strong — typically holding 100+ lbs per bolt. This is what professional installers use whenever possible.

• Weight rating: 100+ lbs per bolt
• Best for: Any drywall or plaster when studs are accessible
• Requires: Stud finder, 3/16" pilot hole, 3" lag bolts

Option 2: Toggle Bolts (Hollow-Wall Anchors)

Toggle bolts (also called butterfly anchors) are the heavy-duty solution for mounting into hollow drywall where no stud is present. They work by threading through a hole, where the wings spring open behind the drywall surface, distributing the load across a wider area.

• Weight rating: 50–100 lbs per toggle in 1/2" drywall
• Best for: Drywall when studs aren't perfectly aligned with mount holes
• Downside: The bolt is permanent — if you remove it, the toggle falls inside the wall and you need a new hole

Option 3: Snap Toggles / SnapSkru (Best Hollow-Wall Anchor)

Snap Toggles (brand name: TOGGLER) are our preferred hollow-wall anchor for TV mounts. Unlike traditional toggle bolts, they use a metal channel that stays in place after installation, letting you remove and reinsert the bolt as many times as you need.

• Weight rating: 265–800 lbs shear strength depending on size
• Best for: TV mounts in drywall where studs aren't available — this is the professional choice
• Requires: A larger hole (1/2"–3/4") but holds significantly better than plastic anchors

Option 4: Molly Bolts

Molly bolts are hollow-wall anchors with a sleeve that expands behind the drywall when the bolt is tightened. They're a step up from plastic anchors but a step down from toggle bolts in terms of holding power for heavy loads.

• Weight rating: 25–50 lbs per anchor
• Best for: Medium-weight wall items — not ideal for TVs over 40 lbs without using multiple anchors
• Tip: Use the sleeve-setting tool if provided — hammering them in directly often damages the drywall

What NOT to Use

These are the anchors that fail and cause TVs to fall off walls:

• Plastic expansion anchors (the cheap ones): Rated for 10–30 lbs. A 65" TV weighs 60–80 lbs. Do the math.
• Self-drilling drywall anchors (EZ-Anchors): Great for light shelves and curtain rods, completely inadequate for TV mounts
• Adhesive mounts: No TV mount should ever rely on adhesive to the wall surface

Quick Reference Chart

• Studs available → 3" lag bolts. Always.
• No studs, drywall → Snap Toggles (TOGGLER) or heavy-duty toggle bolts
• Plaster walls → Find the studs or use 3/8" toggle bolts rated for plaster
• Concrete or brick → Hammer drill + masonry anchors (see our concrete mounting guide)
