Fix Factory know Tek & Facade screws. Tek or Facade Screws are self-drilling screws. Tek Screws are known as ‘self-drilling’ or ‘self-tapping’ because of their drill tip which includes a small carving piece or ‘hex head’. This saves time as the drill tip can be tapped against the wall to create a small hole before drilling it in – eliminating the need to drill a hole first or to wait for the thread to catch. Tek Screws / Self-Drilling Screws are versatile and useful for almost any project. Fix Factory have a wide choice which includes heavy duty self-drilling Tek 7 & 8 screws, steel-to-steel Teks and timber-to-steel wing Teks.
