Self Drilling Screw W/Bonded Washer, Zinc Cr+3 (Inch)
Self-Drilling Screws with a Bonded Washer and Zinc Cr+3 finish are designed to drill, tap, and fasten in a single operation while providing a watertight seal. The bonded washer (metal washer with a rubber backing) helps prevent moisture intrusion and evenly distributes load during installation. The Zinc Cr+3 coating offers moderate corrosion resistance.
These screws are ideal for roofing, siding, metal panels, HVAC systems, and general construction applications where sealing and fastening efficiency are essential. The self-drilling point eliminates pre-drilling, reducing installation time and labor costs. The bonded washer improves vibration resistance and sealing performance, while the Zinc Cr+3 finish protects against rust in indoor and light-duty outdoor environments. Self-Drilling Screws with Bonded Washers provide reliable fastening, weather resistance, and consistent performance across a wide range of applications.
