Best screws for drywall mounting

Drywall mounting is a common task in home improvement and DIY projects, but choosing the right screws can make all the difference in ensuring a secure and long-lasting installation. In this blog post, we’ll explore the best types of screws for drywall mounting, as well as those that are less suitable. By understanding the various options available, you can make informed decisions and achieve professional results with your projects.

Suitable Screws for Drywall Mounting

Drywall Screws:

Drywall screws are specifically designed for fastening drywall to wood or metal studs. They have a bugle-shaped head that allows for easy sinking into the drywall without tearing the paper surface. There are two main types:

Coarse Thread Drywall Screws: 

Ideal for wood studs, these screws have a wider thread pattern that provides a strong grip.

Fine Thread Drywall Screws: Best for metal studs, these screws have a tighter thread pattern that penetrates metal without stripping.

Self-Drilling Screws:

Also known as Tek screws, self-drilling screws are great for mounting drywall to metal studs. They have a sharp, drill-like point that allows them to create their own pilot hole as they are driven in. This makes them ideal for quick and efficient installation.

Anchor Screws:

When mounting heavy items on drywall, anchor screws provide additional support. Types of anchor screws include:

Toggle Bolts: 

These are heavy-duty anchors that expand behind the drywall for a secure hold. They are suitable for mounting heavy objects like shelves and TV brackets.

Molly Bolts: 

These anchors expand behind the wall as the screw is tightened, providing a strong hold. They are perfect for medium-weight items like curtain rods and light fixtures.

Plastic Anchors: 

These are easy to use and work well for lightweight items. They expand as the screw is driven in, securing the anchor in place.

Self-Tapping Screws:

Self-tapping screws are ideal for applications where pre-drilling is not feasible. They can create their own threads as they are driven into the material, making them suitable for both wood and metal studs.

Unsuitable Screws for Drywall Mounting

Wood Screws:

While wood screws are excellent for woodworking projects, they are not ideal for drywall mounting. Their heads are typically too large and can tear through the drywall surface, leading to an insecure hold.

Sheet Metal Screws:

Sheet metal screws are designed for fastening metal sheets and are not suitable for drywall. Their sharp threads can damage the drywall, and they do not provide a secure hold.

Deck Screws:

Deck screws are built for outdoor use and are coated to resist corrosion. However, their aggressive threading and large heads can cause damage to drywall, making them unsuitable for indoor drywall applications.

Lag Screws:

Lag screws are heavy-duty fasteners used for structural applications in wood. They are overkill for drywall and can cause significant damage to the material. Their large diameter and length make them impractical for drywall mounting.

Tips for Choosing the Right Screws

  1. Consider the Weight of the Item: For lightweight items, simple drywall screws or plastic anchors may suffice. For medium to heavy items, toggle bolts or molly bolts are recommended.
  2. Match the Screw to the Stud Type: Use coarse thread drywall screws for wood studs and fine thread drywall screws or self-drilling screws for metal studs.
  3. Check for Corrosion Resistance: If the installation is in a damp environment, consider screws with a corrosion-resistant coating to prevent rust and ensure longevity.
  4. Use the Correct Length: The screw should be long enough to penetrate the drywall and at least 1 inch into the stud or anchor for a secure hold.

By understanding the different types of screws and their appropriate uses, you can ensure a secure and durable drywall installation. Whether you’re hanging pictures, installing shelves, or mounting a TV, choosing the right screws is key to achieving a professional finish and preventing future issues.
