FAQs about Tek Screws

What Is a TEK® Screw?

TEK® type screws are a popular screw type with drill-bit ends that enable them to self-drill. Their innovative tip design allows users to perform drilling applications without creating a pilot hole before fastening.

 

What Are TEK® Type Screws Good for?

TEK® screws are useful for drilling a wide range of materials like metal sheets, aluminum, stainless steel, wood and timber. They are widely used across electrical, insulation, roofing, construction, cladding and HVAC applications.

 

Do You Need a Drill for TEK® Type Screws?

The biggest benefit of TEK® type screws is that you don’t need to drill pilot holes before using them. Many contractors use impact drills for convenience and speed, however, this is NOT recommended by screw manufacturers as the screws were not designed to withhold the force of impact drills.  Keep in mind that even though you do not need a pilot hole, you still need to use a drill to drive in self-drilling screws.

 

How Do You Remove Tek® Screws?

Tek® screws can be easily removed with a driver or similar tool. Fit the driver into the slots on the Tek® screw and unscrew it from the wood. If the Tek® screw is difficult to remove, don’t force it, as too much force can strip the screw and make removal much more challenging.

 

What Materials Are Tek® Screws Good For?

Tek® screws are used for drilling in materials such as:

  • Sheet metal
  • Aluminum
  • Timber
  • Stainless steel
  • Wood

 

These materials are common in applications like:

  • HVAC
  • Insulation
  • Electrical
  • Construction
  • Roofing
  • Cladding

 

Do Tek® Screws Rust?

You can buy tek screws that are manufactured from 410 stainless and 18-8 stainless.  Tek screws made from these materials are more resistant to rust than ones made from carbon steel and are zinc plated.

 

Can You Reuse Tek® Screws?

While we do not recommend this, Tek® screws can theoretically be reused for other projects once removed from the substrate. Since the various Tek® screw types are designed for specific uses, be sure to match your Tek® screw to the right application.

When replacing a screw that you have removed,, you need use a larger diameter screw to ensure a secure fit.

 

What Are the Different Tek® Screw Finishes?

Steel and stainless steel Tek® screws have various finishes available, including zinc plating, and black phosphate. These finishes give the Tek® screw additional protective and functional properties.

 

Various Head Styles of Self-Drilling Screws

All Points Fasteners is pleased to offer several tek screw head styles to meet any customer requirement:

  • Indented hex washer head unslotted: This head style is the most popular with roofing, gutter and siding contractors. They can include a feature a bonded washer that forms a reliable, leak-proof seal, helping to keep out rain and moisture.
  • Phillips modified truss/wafer head: These versatile fasteners are also referred to as round washer head and k-lathe screws. They consist of a large-diameter washer that provides a clean, low-profile surface. They’re an excellent choice for general construction work, HVAC installation projects involving ductwork and a wide range of additional applications.
  • Reamer Tek® screws: These self-drilling screws are ideal for wood-to-metal fastening applications. They feature a pair of metal wings on the screw shank that reams out wood, preventing the premature engagement of the thread. As the screw drills through the wood, the wings break off once they hit the metal.
  • Drywall Tek® screws: As the name implies, these types of self-drilling screws are specifically designed for drywall fastening applications. 
  • Phillips oval head:. They include a uniquely designed curved head that offers a smooth profile and prevents snags during installation work. They’re also easy to install, saving time and effort.
  • Phillips pan head: If you’re looking for a self-tapping, self-drilling screw with a lower profile than an oval or round head product, this item can meet your needs. These screws feature a rounded base with a flat head that rests atop the material it fastens. They are available with a  deep slot drive which enables increased torque with minimal risk of fastener damage. The flatter underside also increases the holding capability by providing more surface area.
  • Phillips bugle: This self-tapping, self-drilling screw consists of a flat top with a countersunk head and a concave bearing surface, making it perfectly suited for drywall fastening applications when attaching the material to metal studs
  • Wafer head Phillips: The innovative conical underhead design ensures a flush fit and bearing surface that’s compatible with softer materials like wood, fiberglass, aluminum and sheet metal. If they are stainless steel or have a cermaic coating, they will provide excellent rust resistance.
  • Trim head: A trim head screw looks much like a flat-head fastener. But a closer inspection reveals the trim version has a smaller surface head. This feature makes the trim head the better choice for applications requiring screws with less noticeable appearances. Consider these fasteners for elaborate carpentry projects or any other job requiring the strength of a screw and the subtle look of a nail.
