Double Barrier Coating Information
- The patented 4CUT tip has a square core and serrated threads to reduce installation torque and make driving easier with no predrilling and minimal wood splitting.
- A new double-barrier coating finish provides corrosion resistance equivalent to hot-dip galvanization. Now one screw can handle interior, exterior and certain pressure-treated wood applications. See Corrosion Information.
- 3/8" hex washer head is stamped with the No-Equal sign and fastener length for easy identification after installation.
The Simpson Strong‑Tie® double-barrier coating is a proprietary two-layer coating that provides a level of corrosion protection that is equivalent to ASTM A153 hot-dip galvanization in most non-marine exposures.
