Picture this: you’ve found the perfect artwork, mirror, or shelf to accent your space, but when you try to hang it, a simple nail or screw wobbles uselessly in the soft drywall. That’s where drywall anchors come in. These clever fasteners ensure your favorite pieces stay securely mounted, eliminating the frustration of sagging or slipping. Learning how to install and use drywall anchors gives you the confidence to transform bare walls into personalized, functional displays.
What is a Drywall Anchor?
Drywall, a pressed gypsum panel, isn’t designed to grip nails or screws by itself. Drywall anchors solve this problem by distributing weight behind the surface. They let you safely hang items like pictures, mirrors, and light shelves without needing specialized tools or studs. By providing a secure hold, anchors prevent drywall damage and keep your décor from crashing down unexpectedly.
Tip: Drywall anchors also work in hollow doors, paneled walls, and other surfaces where direct fastening isn’t feasible.
Basic Installation Steps
Installing a drywall anchor generally follows a simple process:
- Drill a Pilot Hole:
Choose a drill bit slightly smaller than the anchor’s diameter, or follow the manufacturer’s recommendation on the package. - Insert the Anchor:
Gently tap the anchor into the pilot hole with a rubber mallet until it sits flush with the wall. - Add the Screw:
Drive the provided screw into the anchor until it’s snug. The anchor will expand or lock into place, securing your fixture.
Note: For certain anchors like toggle bolts or steel hollow wall anchors, you’ll need a larger pilot hole.
Types of Drywall Anchors
Each anchor style has its own strengths:
- Plastic Expansion Anchors:
Common, budget-friendly, and easy to use. They expand within the wall as the screw is inserted. - Molly Bolts and Steel Hollow Wall Anchors:
Stronger metal anchors that expand or “mushroom” behind the wall. Ideal for medium-weight objects. - Self-Drilling Anchors:
Sharp-tipped anchors that bore directly into drywall without pre-drilling. Great for quick installations, but avoid overtightening. - Toggle and Strap Anchors:
A toggle or wing spreads behind the wall, offering strong support for heavier items like TVs and shelving. - Butterfly Anchors:
Similar to toggles, they combine expansion and threading, good for lighter ceiling or wall-hung decorations.
Choose based on the object’s weight and the wall material. Heavier items often require more robust anchors, while lightweight décor may only need simple plastic expansions.
Lightweight Anchors for Smaller Items
For smaller items like picture frames or decorative shelves:
- Plastic Ribbed Anchors: Hold up to about 10 pounds per pair.
- Threaded Drywall Anchors: Handle roughly 25 pounds per pair.
- Hollow-Wall Anchors: Up to around 30 pounds per pair on plaster or paneling.
These are quick, easy solutions for everyday décor.
Heavy-Duty Anchors for Bigger Loads
If you’re hanging a large mirror, TV mount, or heavy shelving:
- Toggle Bolts: Often hold up to 50 pounds per pair.
- Molly Bolts: Can support around 75 pounds per pair on common wall types.
- Expansion Anchors (Masonry): Up to 100 pounds per pair on concrete or brick surfaces.
- Self-Drilling Anchors (Heavy Grade): Around 150 pounds per pair for drywall and plaster.
When hanging valuable or heavy items, stay well under the rated weight limit for extra safety. Consider using multiple anchors to distribute weight evenly.
Additional Tips for Success
- Check Wall Condition: Make sure the drywall is solid and undamaged before installing anchors. Avoid areas with moisture damage or large patches.
- Weight Ratings: Always verify the anchor’s weight capacity. When in doubt, use sturdier anchors than you think you need.
- Multiple Anchors for Heavy Items: Spread out the load to prevent any single point from failing.
- Larger Screws, Larger Anchors: Heavier-duty anchors accommodate bigger screws, creating a more secure hold.
By understanding the different types of drywall anchors and their proper installation techniques, you can decorate and organize your space without worry. Confidently mount that cherished framed photo, large mirror, or handy shelf and trust that it will remain safely in place.

Wall anchors can hold between 25 to 75 pounds, depending on the type and size. Heavy-duty anchors may support up to 150 pounds.
How do I know what wall anchor to use?
Choose a wall anchor based on the weight of the object. Plastic anchors work for light items, while toggle or molly bolts are better for heavier loads.
Do I hammer an anchor into the wall?
Plastic wall anchors can be gently tapped into the wall with a hammer, while screw-style or toggle anchors require drilling a pilot hole first.
What is the best wall anchor for heavy objects?
For heavy objects, toggle bolts or molly bolts are the best options, as they provide secure support by spreading the load across the drywall.
How much weight can drywall anchors really hold?
Drywall anchors can hold 10 to 150 pounds, depending on the anchor type and wall conditions. Always check the manufacturer's weight limit.
How do you properly install drywall anchors?
To install drywall anchors, drill a pilot hole, insert the anchor, and then screw in the fastener. Toggle bolts require inserting and securing the toggle before tightening.
Do I need a drill for wall anchors?
A drill is recommended for installing wall anchors, especially for harder materials or heavy-duty anchors. Plastic anchors may only require a screwdriver.
What is the best type of anchor for drywall?
Toggle bolts and molly bolts are considered the best drywall anchors for heavy loads, while plastic or self-drilling anchors work well for lighter items.
