  • Screws can be used as replacements for nails or screws that have loosened from wood or steel.
  • 3/8” HWH with EPDM bonded sealing washer provides maximum pull over strength in high wind uplift applications.
  • EPDM rubber & HWH with EPDM bonded washer is vulcanized to a steel washer to form an excellent seal & will cover any existing hole to prevent leaks from
    re-occurring.
