Thread Design: Drywall screws typically have fine threads that are optimized for gripping and securing drywall panels firmly to studs. The threads are spaced closely together to maximize holding power and reduce the risk of pullout or sagging over time.
Sharp Point: Drywall screws usually have a sharp, self-drilling point that allows them to penetrate drywall easily without the need for pre-drilling pilot holes. This feature speeds up installation and reduces labor time.
Bugle Head: Drywall screws feature a flat, slightly rounded head known as a bugle head. The low-profile design of the bugle head allows the screw to sit flush with the surface of the drywall, minimizing the risk of surface damage and creating a smooth finish.
Coarse Thread: Some drywall screws may have a coarse thread with a partial thread or no thread at all near the head. This unthreaded portion helps to draw the drywall tightly against the stud without tearing the paper facing.
Materials: Drywall screws are commonly made from hardened steel or stainless steel to provide strength and corrosion resistance. They may also be coated with zinc, phosphate, or other finishes to enhance durability and prevent rusting, especially in humid or damp environments.
Size: Drywall screws come in various lengths and diameters to accommodate different drywall thicknesses and installation requirements. The most common lengths for drywall screws range from 1 inch to 3 inches, with 1-1/4 inch and 1-5/8 inch being standard lengths for 1/2-inch and 5/8-inch drywall, respectively.
