We continue our series about hardware basics, this time focusing on tek screws. Read on to find out:

In our previous article about wood screws, we wrote all about how to recognize and choose a wood screw that would be ideal for your woodworking project, what they’re made of, and even what type of wood is suitable for what kind of project. You’ll see there’s so much variety with tek screws, too.
So, what makes tek screws different and where are they used?
How to work with tek screws
Tek screws are also called self-drilling screws. That’s because you don’t have to pre-drill when using them.
Tek screws have a specialized tip that’s suitable for cutting into the material you’re working on. All you have to do is tap it against the material and then drill to fasten it.
Some more advantages of tek screws:
- Rust-resistant: they’re made of stainless steel and coated with zinc. These materials won’t corrode
- Durable: they last a long time, no matter the conditions
- They are a time-saver: you’ll have less to clean up because there’s no need to pre-drill. This also means you’ll spend less time working on your project
Sometimes, you can choose to drill a pilot hole. This will ensure that the tek screw goes in as straight as possible.
Make sure the pilot hole is narrower than the tek screw you’re using to make sure the screw fits tightly and the grooves catch to the material.
Where are they used?
Unlike wood screws that can only be used for fastening wooden surfaces, tek screws are a bit more versatile. They can be used to attach wood to metal or metal to metal.
They are commonly found in the electrical industry, roofing, and heavy machinery building.
Tek screw sizes
When deciding on what size of tek screw you need, it’s best to consult the manufacturer’s size chart as sizes vary.
Always make sure that the size of the hardware you’re working with is suitable for the thickness of the material you have to fasten.
Usually, a number system is used to indicate the size. The larger the number, the larger the screw size.
Different head types
Tek screws come in a variety of head types:
- Hex (hexagonal): they are sturdy and offer a tight fit, ideal for drilling through different types of metal
- Low profile: use when you need a snug fit as this head type doesn’t poke out of the hole
- Panhead: ideal for simpler projects
- And more …
Tek screws for use in the roofing industry
- Sheet to steel roofing tek screws: heavy-duty screws designed for joining metal roofing to steel frames. Rust-proof. They come in a variety of sizes and can include a washer
- Sheet to timber tek screws: designed for fastening metal roofing panels to wooden frames
Always choose the best hardware that suits your project and ensures safety and longevity.
