Product Overview

Our phosphate-free carbon steel drywall self-tapping screws are designed to provide reliable and efficient fastening solutions in drywall installation and various other construction applications. With a size of 3.5*40mm and a convenient packaging of 500 pieces per box, these screws offer both quality and quantity to meet your project requirements.

Features and Benefits

Strong and Durable: The carbon steel construction gives the screws excellent strength and durability, capable of withstanding the stresses and loads in typical drywall installations and light construction tasks.
Easy to Use: The self-tapping design eliminates the need for pre-drilling in most cases, saving time and effort during installation. The sharp threads bite into the drywall and underlying studs or frames smoothly.
Corrosion Resistance: The phosphate-free coating offers reliable protection against rust and corrosion, ensuring the longevity of the screws even in moderately humid or corrosive environments. This helps maintain the integrity of the fastened structures over time.
Versatile Application: Suitable for a wide range of drywall applications, including attaching drywall panels to wooden studs, metal frames, or other substrates. Can also be used in light fixture installation, trim work, and other similar construction and DIY projects.
