  • Thicker gauge under the head
    The 12 gauge main body of the screw allows for easy installation into timber or steel, while under the head the 14 gauge thread grips the sheeting and decreases the possibility of water entry.
  • New 12G thermoset seal*
    The new thicker, 12 gauge thermoset seal encapsulates under the head of the fastener and reduces splitting, bulging or leaking in occasions of overdriving.* Not to be used in conjunction with Metal Profile Washers and in thermal expansion situations.
