The Ultimate Drywall Screw For Your Next Project

Drywall screws are used to attach drywall to wood or metal studs. The #8 x 1-1/2 self-drilling drywall screw with a Phillips bugle head and zinc coating is designed for drywall-to-metal fastening jobs. The bugle head sits flush with the drywall once installed, and the zinc coating is suitable for dry interior environments. This type of screw eliminates the need for pre-drilling, making it a convenient choice for construction and home improvement projects.

Daggerz™ Self-Drilling Drywall Screws

The zinc coating on the Daggerz™ screws is an important feature, providing a clean, finished look to your project. However, it is important to note that this coating is only suitable for dry interior environments. For exterior or moist environments, you may need to consider a different type of screw or coating to prevent rust and corrosion.

The Daggerz™ self-drilling drywall screws are made of carbon steel, with 18 threads per inch. The point type is #2 Drill, and the drive type is #2 Phillips. The head type is a bugle head, which provides a discreet appearance as it blends in seamlessly with the drywall. The diameter of these screws is #8, and they are available in two lengths: 2" and 2-3/8".

These screws are sold in packages of 3,000, providing an ample supply for your drywall-to-metal fastening needs. With their self-drilling capabilities and drywall-specific design, the Daggerz™ brand screws offer a reliable hold and ease of installation, making them a great choice for your next project.

The #2 self-drilling point removes the need for pre-drilling

The #2 self-drilling point on the 8 x 1-1/2 in zinc-plated bugle-head self-drilling drywall screw is a convenient feature that offers a range of benefits to users. Unlike other types of screws, such as thread-cutting or thread-rolling self-tapping screws, this particular screw's self-drilling capability eliminates the need for pre-drilling. This is made possible by the design of the screw's tip, which includes a drill point similar to that of an actual drill bit.

The #2 self-drilling point is specifically engineered to easily drill through metal, making it ideal for drywall-to-metal fastening jobs. This feature simplifies the installation process by allowing the screw to create its own hole and mate objects together in a single operation. This not only saves time but also ensures a secure connection between the drywall and metal without the additional step of pre-drilling.

The self-drilling point of this screw measures Tek 2 in length, which is suitable for a wide range of applications. Tek screws are categorised by the length of their drill point, with Tek 7 being the longest. The length of the #2 drill point strikes a balance, making it versatile for various projects.

The zinc-plated bugle-head self-drilling drywall screw is a high-quality fastener designed for efficiency. By incorporating the #2 self-drilling point, it removes the need for pre-drilling, streamlining the fastening process and making it a convenient choice for both professionals and DIY enthusiasts.

The bugle head sits flush with the drywall once installed

#8 x 1-1/2 in zinc-plated bugle-head self-drilling drywall screws are designed for drywall-to-metal fastening jobs. The #2 self-drilling point can easily drill through metal, eliminating the need for pre-drilling. These screws are specifically designed to anchor drywall to metal, and the bugle head sits flush with the drywall once installed.

The bugle head screw features a unique design with a countersunk head, a flat top, and a concave under-head bearing surface. This design enables the distribution of bearing stress over a wider area compared to a flat-head screw. The smooth, flush finish of bugle head screws works well for a wide range of applications.

Bugle head screws are ideal for situations where the screw must lie flush with the material, and they eliminate the need to pre-drill a countersinking hole. They are commonly used to fasten drywall to wood or metal studs, but they can also be used for various construction fastening tasks and other applications.

The zinc coating on the #8 x 1-1/2 in bugle-head drywall screws is essential to note. It is only suitable for use in dry interior environments. This limitation is crucial to consider when selecting the appropriate fasteners for specific projects or environments.

Overall, the bugle head design provides a smooth and flush finish, making it a versatile and attractive option for many applications beyond just drywall installation.

The zinc coating is only suitable for use in dry interior environments

The zinc coating on the #8 x 1-1/2" self-drilling drywall screw is only suitable for use in dry interior environments. Zinc is a natural, healthy, and abundant element that has been used in construction since 79 AD. It is a well-suited corrosion-protective coating for iron and steel products due to its excellent corrosion resistance in most environments.

Zinc's corrosion resistance is a result of its ability to form dense, adherent corrosion byproducts, which leads to a rate of corrosion considerably lower than ferrous materials. When exposed to the atmosphere, zinc corrosion products develop rapidly on the surface as the coating is exposed to natural wet and dry cycles. These corrosion products, collectively known as the zinc patina, act as an additional barrier between the steel and the environment.

However, zinc is not suitable for all environments. While zinc can provide protection in dry climates, it is not recommended for exposure to chlorinated water. For wet climates or exterior use, hot-dip galvanised steel is a more suitable option. This is because zinc is a "sacrificial anode", meaning it protects the steel by sacrificing itself. When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3). This zinc carbonate is a usually dull grey, fairly strong material that stops further corrosion in many circumstances, protecting the steel below from the elements.

Therefore, the zinc coating on the #8 x 1-1/2" self-drilling drywall screw is specifically designed for use in dry interior environments to ensure optimal protection against corrosion.

8 x 1-1/2 in Zinc-Plated Bugle-Head Self-Drilling Drywall Screw

About the Screw

This screw is designed for drywall-to-metal fastening jobs. The sharp drilling point can easily penetrate metal, and the bugle head sits flush with the drywall once installed. The zinc coating is only suitable for dry interior settings.

Carbon Steel Composition

Carbon steel is known for its versatility, making it suitable for a wide range of applications, including fasteners like screws. It can be heat-treated to improve its properties, and it is often used in the construction industry due to its excellent strength-to-weight ratio.

The specific type of carbon steel used for these screws likely falls into one of the following categories:

• Low-carbon steel: Contains up to 0.3% carbon, offering good machinability and ductility.
• Medium-carbon steel: Contains 0.3% to 0.6% carbon, balancing ductility and strength.
• High-carbon steel: Contains more than 0.6% carbon, maximizing hardness and strength.

By utilizing carbon steel, these self-drilling drywall screws gain the necessary toughness and durability to effectively fasten drywall to metal studs or frames.
