What Size Screws Do You Use for 5/8” Drywall?
When it comes to installing drywall, choosing the right screws is critical for ensuring that the panels are securely fastened while also allowing for a smooth finish. For 5/8-inch drywall, which is often used in commercial spaces and for soundproofing, knowing the appropriate screw size, type, and installation technique is essential for achieving optimal results.
Understanding Drywall Thickness
Drywall comes in various thicknesses, with the most common types being 1/4”, 1/2”, and 5/8”. The 5/8-inch drywall is particularly popular due to its fire resistance and ability to minimize sound transmission. However, its heavier weight requires specific screws for effective installation.
Recommended Screw Size
For 5/8” drywall, the best choice is typically a screw that is 1 1/4 inches long (also denoted as 6 or 7 gauge). This length ensures that the screw penetrates the drywall adequately and reaches the stud or the metal framework to provide a solid hold. While you may see longer screws (1 5/8” to 2”) used in some applications, they can unnecessarily risk damaging the drywall or framing behind it.
Types of Screws
Drywall screws come in various types, but the two main categories are coarse-thread and fine-thread screws.
1. Coarse-Thread Screws These are designed for use with wood studs. The coarse threads provide better grip in softer materials, which is essential for securing the drywall tightly against the framing.
2. Fine-Thread Screws These are typically used with metal studs. Fine-thread screws have more threads per inch, allowing for better grip in harder materials and reducing the risk of stripping.

Choosing the right type of screw according to your stud material is crucial for achieving a secure installation.
Installation Technique
When installing 5/8” drywall, appropriate screw placement is as vital as selecting the right screw size. The screws should be placed approximately every 12 inches along the edges and every 16 inches in the field of the panel. This spacing helps to ensure that the drywall is well-supported and reduces the likelihood of cracks and sagging.
The screws should also be recessed slightly below the surface of the drywall without breaking the paper face. This allows for the application of joint compound (mud) for a smooth finish. Overdriving the screws can lead to damage to the drywall, while underdriving can leave visible screw heads after finishing.
Additional Tips
- Screw Quality Always choose high-quality drywall screws to avoid issues such as snapping during installation. Coated screws are often more resistant to rust and provide better holding power.
- Appropriate Tools Using a drywall screw gun can help achieve consistent depth and reduce the risk of damaging the drywall. If using a cordless drill, set the clutch to a low setting to prevent overtightening.
- Avoiding Problems Be cautious not to over-tighten screws, as this can lead to dimpled areas in the drywall and require additional mudding. Practice good technique by keeping your wrist straight and applying steady pressure.
Conclusion
Installing 5/8” drywall require careful consideration regarding the size and type of screws used. By opting for 1 1/4 inch coarse-thread screws for wooden studs and fine-thread screws for metal studs, and following proper installation techniques, you can achieve a durable and visually appealing finish. Remember, the foundation of a good drywall installation lies in the quality and application of the screws, so take your time to plan and execute the process correctly. With the right tools and techniques, your drywall project will stand the test of time, ensuring both structural integrity and aesthetic appeal.
