Drywall screws are also known as gypsum screws, are specialized fasteners designed for attaching drywall to wall studs. Differing from regular screws, drywall screws provide superior holding power. The feature of bugle head can prevent drywall paper damage, ensuring a secure and clean attachment.
1. The common type of screw threads
Choosing the right screw thread type is very important for effective drywall installations. Here are two primary thread types:
- Fine Thread: Fine-thread drywall screws are optimized for metal framing or metal studs, allowing efficient gripping and reduce the risk of stripping.
- Coarse Thread: Coarse thread drywall screws are designed for wood framing or wood studs. The wide thread for a stronger hold and thicker core diameter to avoid bending.
2. The type of screw points
The point type on a drywall screw impacts its accessibility of use and effectiveness based on the material. Here's a quick guide to classify drywall screw points:
- Sharp Point: Sharp-point drywall screws are specifically designed to penetrate wood quickly and easily. The recommended uses like interior wall, ceiling, wood framing and board setups.
- Drill Point: Self-drilling drywall screws have a built-in drill tip that cuts through metal quickly, without pre-drilling. The recommended uses like metal stud framing, metal backing installation and steel frame assemblies.
- G2: Patent G2 drywall screws feature the fast and stable penetration. Available used for light gauge steel to light gauge steel combination, also known as metal framing screws.
3. Drywall board jointing
When joining two drywall boards, it's essential to use laminating screws, which are specifically designed for board-to-board drywall installations, commonly used in soundproofing project or fire-rated applications.
4. Choosing the right length for drywall screws
Selecting the appropriate screw length is crucial to securely attach drywall to studs. Here’s a quick guide:
