What Screws to Use for Stair Treads

Discover which screws are best for securing your stair treads. Our expert guide covers the best types and methods for a safe, durable staircase.

Are you wondering what screws to use for stair treads? Selecting the right type of screws is essential for ensuring that your stair treads are not only firmly attached but also maintain their appearance and functionality over time.

For securing stair treads, it's best to use #9 or #10 wood screws that are long enough to penetrate through the tread and firmly into the stair stringer.

Note: While wooden stair treads use screws, carpet stair treads use adhesive.

This guide will provide you with detailed insights into choosing the best screws that enhance the durability and safety of your stair treads, transforming your staircase into a safe and elegant part of your home.  

The Importance of Choosing the Right Screws   

Why the Right Screws Matter 

The right screws do more than just hold your stair treads in place—they ensure durability, safety, and integrity of the staircase. Using the incorrect screws can lead to issues like squeaking stairs, or worse, treads that shift or become loose over time.

What Kind of Screws to Use on Stair Treads   

Selecting the Best Screws for Durability and Strength 

When it comes to stair treads, the consensus among professionals is to use high-quality, durable screws such as #9 or #10 wood screws. These screws should be long enough to penetrate both the tread and into the stair stringer by at least half an inch. This ensures a tight fit that won’t loosen easily due to the weight and constant traffic on the stairs.

Materials Matter: Stainless Steel vs. Galvanized 

For indoor stairs, stainless steel screws are often recommended because they are strong and resist corrosion. For outdoor stairs, consider galvanized screws that can withstand the elements better, preventing rust and ensuring longevity.

How to Install Stair Treads with Double Sided Tape   

A Nail-Free Alternative: Double-Sided Tape 

For those looking for a less permanent or less invasive method, Installing stair treads with double-sided tape offers a viable alternative. This method is particularly useful for temporary installations or for surfaces where screws are not desirable.

What is the Best Way to Secure Stair Treads?   

Combining Screws and Adhesives for Maximum Security 

While screws provide physical strength, pairing them with a construction adhesive can prevent movement and squeaking. This combination is often considered the best practice for achieving a secure, long-lasting installation.

Installation Tips and Tricks   

Pre-drilling to Prevent Splitting 

Always pre-drill holes for the screws to prevent splitting the wood, which can compromise both the aesthetics and the structural integrity of the staircase. The pre-drilled hole should be slightly smaller than the diameter of the screw to ensure a snug fit.

Ensuring Even Placement and Alignment   

Measuring for Symmetry 

To keep your staircase looking uniform, measure the placement of the screws on the first tread and use this as a guide for the rest. Consistency is key to a visually appealing finish.

Advanced Techniques for Stair Tread Installation   

Using Counter-Sunk Screws for a Flush Finish 

Consider using counter-sunk screws that allow the head of the screw to sit flush with the surface of the tread. This not only looks better but also prevents any tripping hazards or discomfort while walking on the stairs.


Choosing the right screws for your stair treads is crucial for ensuring a safe, durable, and aesthetically pleasing staircase. By understanding the specific needs of your installation, whether indoor or outdoor, and combining the best materials with the right techniques, you can achieve a professional-level outcome that lasts for years. Remember, it's not just about making your stairs safer; it's about enhancing the overall appeal and value of your home.
