5. Precast Elements M20 bolts are used to connect precast concrete elements during assembly, providing quick and effective ways to join large structures without extensive welding or other complex methods.

Self-tapping screws are designed to create their own hole as they are driven into materials, eliminating the need for pre-drilling. This feature significantly enhances the efficiency of installation processes, making them a popular choice among professionals and DIY enthusiasts alike. Available in different sizes and materials, self-tapping screws can be utilized in metal, wood, or plastic applications. Their ease of use and reliability make them ideal for a wide range of projects from home repairs to large-scale constructions.

4. Resistance to Corrosion Many metal expansion nuts are available in corrosion-resistant materials, such as stainless steel or coated metals, which are ideal for outdoor or humid environments.

The self-drilling feature of Tek screws is particularly beneficial when working with metals and other hard materials. This allows for seamless integration into projects involving metal roofing, siding, and similar applications, where traditional drilling methods might be cumbersome and time-consuming.

Roof self-drilling screws are specialized fasteners designed for steel and metal roofing systems. As the name suggests, these screws have a built-in drill point that allows them to penetrate roofing materials without the need for pre-drilling. This feature not only saves time during installation but also enhances the overall integrity of the roof by reducing the likelihood of leaks that can occur from improperly placed fasteners.

Washer head machine screws are characterized by their broad, flat heads that resemble a washer. This design provides a larger bearing surface than standard screws, which helps distribute the load more evenly across the material being fastened. The head’s geometry often includes a recessed area for a driver, facilitating easy installation and removal. Additionally, these screws are typically made from high-strength materials such as stainless steel, carbon steel, or alloy steel, ensuring durability and resistance to corrosion and wear.

Due to their unique advantages, 2% self-drilling screws find applications in a wide array of sectors. In the construction industry, they are regularly used for securing metal roofing and siding, providing a strong hold that withstands weather elements. In the automotive industry, these screws assist in assembling parts securely without compromising the integrity of the materials involved.

Various types of expanding plastic screw anchors are available in the market, each designed to accommodate different weights and materials. The most common types include
