To effectively attach drywall to studs, you’ll need to select the correct size of screw. While there is a huge variety of screw sizes available for building work, there are only a handful of sizes that are suitable for use with drywall.
You can typically find these under the heading of ‘drywall screws’ at the hardware store, though you might be interested to know that each screw size is appropriate for a particular type of drywall. Here we look at the drywall screw size you should be using for various drywall projects.

幹牆螺杆長度
Standard drywall has a thickness of half an inch.This is the most common type of drywall used in home building, which will be needed for the majority of drywall projects. Other types of幹牆包括X型幹牆，其具有略微厚的⅝英寸測量。This is thetype of drywallyou would need to use on certain areas of condos or multi-family homes to meet fire safety codes.
交叉形幹牆還用於爐房間和我n garages, as these are the most common areas where fires start. This type of drywall works to reduce the spread of flames, and due to its thickness, will need a slightly longer length of screw to keep it securely in place.
您還可以獲得比標準半英寸測量更薄的幹牆，厚度僅為四分之一英寸。該幹牆是柔性的，所以用於實現彎曲的牆壁。由於具有更淺的深度，適用於這種類型的幹牆的螺釘可以稍短。
The recommended length of screw for working with standard drywall is 1 ¼ inches.這是最常見的螺釘人員使用幹壁工程，將幹牆紙連接到木壁螺柱上。For thicker drywall measuring ⅝ inches, you should use screws that fall into the range of 1 ⅝ and 2 inches in length.
In instances where thicker drywall is used on ceilings, it is common to use screws measuring 1 ⅝ inch，這允許一整英寸的螺杆下沉到下麵的木梁中。這將有助於防止在天花板上下垂並應對額外的重量。For thinner drywall, use screws that are a minimum of 1 inch in length and a maximum of 1 ¼ inch.
For ease, keep this information to refer back to later if you are unsure of which length of screws to use with your drywall:
- ¼ inch drywall = 1 inch to 1 ¼ inch long screws
- ½ inch drywall= 1 ¼ inch to 1 ⅝ inch long screws
- ⅝ inch drywall= 1 ⅝ inch to 2 inch long screws
Drywall Screw Thread
As well as the length, the thread on a drywall screw will impact its effectiveness. Drywall screws will come in a coarse thread or a fine thread, and they are best suited to different types of projects. For most people who are attaching drywall to wooden studs, coarse threaded screws are undoubtedly the best option.
這些螺釘與木材很好，因為它們鎖定到木材上，並在進一步滲透時將幹牆拉到螺柱上。
這導致安全修複和良好的級別完成。因此，粗螺紋螺釘是最常用的type of screwsfor the majority of drywall construction. Just be sure to wear gloves when working with these screws because they have a tendency to throw out metal burrs which can sink into your skin.
Fine threaded screws also have their place in drywall construction. These types of screws are best for projects which require you to attach drywall to metal studs. This is a less common situation, which is why these types of screws are less widespread compared with coarse drywall screws.
Fine threaded screws are self-threading and are able to grip into metal surfaces better than coarse screws. If you tried to use a coarse drywall screw with metal work, you would likely find that the screw will chew up the metal stud, resulting in a loose hold. Similarly, fine threaded screws are unable to grip into the wood as well as coarse screws, which is why these are not recommended for use when attaching drywall to wooden studs.
- Wooden studs= Coarse thread screws
- Metal studs= Fine thread screws
Drywall Screw Gauge
螺釘的儀表是與螺釘的直徑測量有關的數字。要了解螺釘儀表，您需要記住，數量越高，螺釘的直徑越大。
對於幹牆螺絲，最常見的是需要它們的標準＃6。這轉化為0.1380英寸的實際直徑測量。當為螺釘購物時，螺釘的規格通常在長度之後列出。因此，例如，將在商店中示出為“1.×6”，將在商店中示出了具有1¼英寸的長度測量的螺釘和6的螺釘。
對於幾乎所有的幹牆安裝，儀表為6將是合適的，但在某些情況下，您可能希望使用更厚的儀表，例如＃8，其實際術語將是0.1640英寸的直徑測量。
完成其他項目時，不要誘惑使用儀表＃6螺絲，因為它們將在大多數其他應用程序中捕捉。對於擰緊底座或其他非幹牆材料，您應該使用最少的儀表＃8螺釘，因為這些表麵對於＃6螺釘太密集，並且會導致破損。
Drywall Screw Coatings
Most drywall screws will either be coated in phosphate or zinc. Phosphate offers better protection against rust if you are fixing drywall in an area that might be susceptible to moisture. Gray and black phosphate coatings are widely available; note that black phosphate coating is more likely to cause staining due to the types of dye used.
