Hex Head Fine Thread

These Hex Head Fine Thread Tek Screws are purpose-built for securing profiled metal sheeting to hot rolled steel substrates. With a self-drilling point capable of penetrating steel between 5.0 mm and 12.5 mm thick, they eliminate the need for pre-drilling, saving both time and labour on site. The fine-threaded design ensures a secure grip in steel, reducing the risk of loosening under vibration or thermal expansion. The hex head provides reliable torque transfer and makes installation easier with power tools in roofing and cladding applications. Ideal for industrial and commercial builds, the screws are available in a variety of lengths to accommodate different fixture thicknesses. Whether fixing lightweight sheeting or deeper profile panels, there’s a length to suit your project.
