Tek Screws FAQ & Applications for Construction Suppliers
- Tek Screws
Tek screws are a staple in the construction industry, known for their self-drilling capabilities that save time and effort. The name “Tek” used to be a brand name for this type of screw but has now become one of the common ways that people in the construction industry refer to these types of self drilling screws. At Cheng Hao we manufacture a huge range of fasteners for the construction industry and in this article we will provide you with answers to some of the most common questions that we see about this type of screw.

What Are Tek Screws?
Tek screws are often referred to as self-drilling screws and are designed to drill their own holes as they are driven into materials. This removes the need for a pilot hole, making them highly efficient for fast-paced construction projects.
Tek screws are typically made from materials like carbon steel or stainless steel and are often coated with protective finishes such as zinc or black phosphate to enhance their durability and resistance to corrosion. The screws are available in various sizes and tip types, each designed for specific applications, from light-duty tasks to heavy-duty projects involving thick metal.
How to Identify Tek Screws
Identifying Tek screws is straightforward due to their distinctive drill-bit end, which sets them apart from other types of screws. The tip of a Tek screw is designed to penetrate materials without the need for pre-drilling, making it instantly recognizable.
How to Choose the right size of Tek Screw
Tek screws come in different sizes, typically ranging from #6 to #14 in diameter, with #6 being the thinnest and #14 the thickest. The tip size of a Tek screw, designated by a number from 1 to 5, indicates the thickness of the material it can penetrate. For example, a TEK 1 screw is suitable for thin metal and wood, while a TEK 5 screw is designed for thicker metals.
When selecting a Tek screw for your project, it’s essential to consider the type of material you’re working with and the thickness of that material. This will help you choose the appropriate tip size and screw diameter, ensuring a secure and reliable connection.

Common FAQs About Tek Screws
What Are Tek Screws Used For?
Tek screws are incredibly versatile and are used in a wide range of applications. Their self-drilling feature makes them ideal for metal-to-metal and metal-to-wood connections, commonly found in:
- Metal Roofing: Tek screws are widely used in metal roofing to secure metal sheets without the need for pre-drilling.
- HVAC Installations: These screws are essential in HVAC systems for fastening ducts and other components.
- Electrical Installations: Tek screws are used to mount electrical panels and other fixtures to metal surfaces.
- Cladding and Siding: They provide a secure fastening solution for exterior cladding and siding projects.
By eliminating the need for pre-drilling, Tek screws save valuable time on these projects, making them a preferred choice for many contractors.
Do You Need a Drill To Install Tek Screws?
Yes, while Tek screws eliminate the need for a pilot hole, you still need a drill or an electric screwdriver to drive them into the material. It’s important to use the correct drill settings to avoid overtightening, which can strip the screw head or damage the material.
It’s worth noting that while many contractors use impact drills for convenience, this is not recommended for Tek screws. The high impact force can compromise the screw’s ability to hold in place and may even cause the screw head to pop off. Instead, use a regular drill at a moderate speed to ensure a secure installation.
Can You Reuse Tek Screws?
Reusing Tek screws is generally not recommended, although it is possible in some cases. When a Tek screw is removed, it can leave the material with a slightly enlarged hole, making it challenging to achieve the same level of hold if reused. If you must reuse a Tek screw, consider using a screw with a larger diameter to ensure a secure fit.
Do Tek Screws Rust?
Tek screws are available in materials and finishes that offer varying levels of corrosion resistance. For example, stainless steel Tek screws are more resistant to rust than carbon steel screws, especially those made from 410 or 18-8 stainless steel. Additionally, many Tek screws are coated with zinc or black phosphate, further enhancing their resistance to rust and corrosion.
For outdoor applications or projects in harsh environments, choosing Tek screws with a higher level of corrosion resistance is crucial to ensure the longevity of your work.
Different Types of Tek Screws & Their Applications
Tek screws come in various head styles and designs, each suited for specific applications. Understanding the different types of Tek screws will help you select the right one for your project.

Benefits of Using Tek Screws
Tek screws offer several advantages that make them a preferred choice for many construction projects:
- Time Savings: The self-drilling feature of Tek screws eliminates the need for pre-drilling, significantly reducing installation time.
- Versatility: Tek screws are available in a wide range of sizes and designs, making them suitable for various materials and applications.
- Corrosion Resistance: Many Tek screws are made from stainless steel or coated with protective finishes, providing excellent resistance to rust and corrosion.
- Consistent Performance: Tek screws are engineered to deliver consistent performance in even the most demanding environments, ensuring a secure and reliable connection every time.
What to Consider When Buying Tek Screws
When purchasing Tek screws, there are several factors to consider to ensure you choose the right product for your project:
Head Style
The head style of the screw determines how it distributes stress and the appearance of the finished surface. For example, hex washer heads are ideal for roofing projects, while modified truss heads provide a larger bearing surface for general construction.
Shank Size
The shank size refers to the thickness of the screw. A thicker shank is recommended for heavy-duty applications, while a thinner shank may be sufficient for lighter tasks.
Length
The length of the screw should be based on the thickness of the materials you are fastening. For countersinking screws, measure the entire screw length to ensure it will be fully embedded in the material.
Material and Coating
The choice of material and coating affects the screw’s performance and durability. Stainless steel screws offer superior corrosion resistance, while zinc-coated screws are suitable for general-purpose applications.
