Self-drilling screws, often referred to as Tek screws, are specialized fasteners that possess a unique drill point. This drill point enables the screw to create its own hole in the material, eliminating the need for pre-drilling. When combined with the galvanized coating, which provides excellent corrosion resistance, these screws become ideal for outdoor and high-humidity environments.

One of the key advantages of expansion anchors is their ease of installation. Unlike traditional anchor systems that require specialized tools and equipment, expansion anchors can be installed quickly and easily using just a drill and a screwdriver. This makes them ideal for projects where time and efficiency are of the essence, such as emergency repairs or quick installations.

Butterfly screws, also known as toggle bolts, are a type of fastener that features a pair of wings that fold during installation and expand once they are inside a pre-drilled hole. The design allows for a stronger grip on hollow walls, such as drywall, where regular screws might not provide sufficient anchoring. Butterfly screws are particularly useful for mounting heavier items like televisions, where the risk of falling can be a significant concern.

2. Corrosion Resistance Many resin formulations are inherently resistant to chemicals and environmental degradation, making 10mm resin anchor bolts ideal for outdoor or industrial settings where exposure to harsh elements is a concern.

2. Corrosion Resistance Many manufacturers provide M20 bolts with coatings or treatments (like galvanization) to enhance corrosion resistance. This is vital for outdoor and industrial applications where exposure to moisture and chemicals is common.

Chemical anchor bolts are versatile and can be used in a variety of applications, including

2. Durability Made from high-strength steel and often coated for additional corrosion resistance, these screws are designed to withstand harsh environments. This makes them ideal for outdoor applications where exposure to elements can lead to rust and deterioration.

3. Tapered or Flat Underheads The design of the underhead can vary. A flat underhead ensures even pressure distribution, while a tapered design can help in locking the bolt in place, reducing the likelihood of loosening under dynamic loads.

The T-head screw's defining feature is its T-shaped head, which provides a larger surface area than traditional screws. This configuration enables better load distribution and greater resistance to pull-out forces. Typically manufactured from high-strength materials such as stainless steel or carbon steel, T-head screws are designed to endure significant load and stress. The screw's threading, which can be either coarse or fine depending on the required application, ensures a secure fit. Moreover, the T-head allows for easy installation using standard tools, making it user-friendly for both professionals and DIY enthusiasts.

Another crucial aspect of bolt structure is the surface treatment of bolts, which can significantly improve their performance. Surface treatments such as galvanization, coating, or anodizing can enhance a bolt's resistance to corrosion and wear, extending its service life. For instance, galvanized bolts are coated with zinc to prevent rusting, making them suitable for outdoor applications. Similarly, anodized bolts, commonly used in aluminum alloys, have a protective oxide layer that not only enhances corrosion resistance but also improves aesthetic appeal.

Key Features

Self-drilling screws, also known as drill point screws, are designed with a sharp tip that allows them to create their own hole in the material being fastened. This eliminates the need for pre-drilling or pilot holes, making the application process much faster. The availability of different sizes, including 2 inches in length, allows for versatility in use across various materials such as wood, metal, plastic, and composite materials.
