Product description

Hex Head Self Drilling Screws with EPDM Washer

  • Material: Both the screw and the metal washer are made of carbon steel, a zinc-plated surface finish, which is corrosion-resistant; the black washer is made of EPDM, which is wear-resistant and oxidation-resistant.
  • Advantages: The hex washer head has a flange with an EPDM rubber washer on the bottom to prevent leaks, loosening and damage to mating surfaces. When you tighten the self-drilling screw, a flexible black EPDM rubber washer bonded to the metal washer creates a tight seal.
  • Easy to use: Unlike self-tapping screws, these self-drilling screws drill a hole and tap a thread in one operation. All you need to install them with a power drive tool.
  • Application: Hex head self-drilling screws are typically used in metal-to-metal and metal-to-wood applications. Widely used in the electrical and industry, most commonly on thin metals, for example with roofing, steel studs, etc.
