Types of Tek Screws

Tek screws, also known as self-drilling screws, combine screw agility and drill bit precision. They’re ideal for fastening materials together without pre-drilling, and they can be used in a wide range of applications including fixing composite panels to metal, roofing, cladding, hot and cold rolled rails and purlins, as well as for securing HVAC components and liner panels.

There are many different types of tek screws to choose from and determining which ones are right for your project will depend on factors like head type, drive, shank size, length and diameter. For example, flat screw heads install so they’re flush with the surface of the material while hex screw heads have an angled bearing surface and a rounded top that sits above the surface of the material and can be driven into it using more force.

Tek screws are also distinguished by their TEK point size, which has to do with the length of the tip and how thick of metal it can drill through without needing to have a pilot hole first. Typically, a TEK 2 or 3 point can pierce steel up to 20-gauge and a TEK 4 or 5 can handle the thicker stuff. Choosing the right TEK point for your job will make all the difference as it can significantly reduce the amount of work you need to do and help you get the job done faster.
