Tek screws are a versatile choice for many mechanical insulation projects. They combine screw agility with drill bit precision, making it easier to fasten materials without pre-drilling.
Choose the head and drive type that best matches your needs. Screws with hex drives fit a wrench, while those with Phillips heads work with most manual and electric screwdrivers.
Easy to Assemble
Whether you’re working with electrical wires, installing roofing or something else altogether, you can save time and energy when you use tek screws. They have a self-tapping thread and drill point on them, eliminating the need to pilot drill first before fastening.
Typically made from hard metal, they’re heat treated to ensure that their drill point will successfully pierce the surface of the material you’re screwing into. This hardiness makes them a great choice for working with metal panels and roofing.
You can choose from a variety of head styles, including hex and Torx, depending on your application. You can also select the drill point size, with TEK points of 2 and 3 commonly used for general components, while 4-5 is great for stitching cladding panels. Whatever type of tek screw you use, be sure to drive them in slowly and don’t tighten too much, as this can lead to the heads stripping, making it difficult to remove the screws later.
No Pilot Holes Needed
In the fastening world, there are roughly twelve bajillion ways to fasten things together. And because of the number of options, sometimes fasteners that serve similar purposes get confused with one another. For instance, self-drilling screws—often referred to by the Tek and ZIP brand names—and self-tapping screws can get mixed up, but they are actually two different fasteners.
Tek screws have drill-bit points that allow them to drill their own beginning hole and tap their own threads in one operation, meaning no pre-drilled pilot hole is needed.
They’re also easy to use by hand or with electric screwdrivers. While it’s possible to create a pilot hole for some materials—such as thick metals—it’s not necessary for most applications. That said, if you’re drilling into a soft or composite material, it might still be best to pre-drill in order to ensure the screw goes in smoothly and securely. Otherwise, you can simply jump straight into fastening. Regardless of what you’re working with, a Tek screw will help you get the job done faster and more efficiently.
Tek screws come in several different varieties, each with slight differences that make them better for certain projects. You can find them with a Phillips modified truss head for a clean, low-profile surface or hex heads for easy driving. They also can have a Phillips square drive, which is becoming more popular for contractors that do heavy metal work. The drill point size dictates the type of material the screw can drill through. For example, a TEK 2 can penetrate lighter grades of metal while a TEK 4 or 5 can cut through thicker metals.
Tek screws are used in many different applications such as metal cladding, roofing jobs, and stitching casing panels to steel. They can be driven with a standard power drill or electric screwdriver. However, you should always drive them slowly to avoid stripping the heads or removing the coatings. Too much force can also cause them to deform. Choose the right type of fastener for each project to ensure you’re using it correctly and safely.
Tek screws eliminate the need for pre-drilling holes on surfaces, which speeds up projects and saves time. Contractors, metalworkers and other professionals working with thick materials often turn to tek screws to help them meet the challenges of their jobs.
The selection of the right screw for a specific project will depend on the type and thickness of material, as well as other factors like how much pressure the screw must withstand. Professionals will also need to select the head style, thread pattern and driving recess that are best for their applications.
A hex head self-drilling tek screw, for example, features a drill point that cuts its own threads to penetrate the surface of metal and wood. The length of the drill tip determines how thick a material it can pierce without a pilot hole. The screw’s Tek number is usually based on the length of this drill tip, with a hex screw that has a Tek 3 point being able to pierce thinner metals.
