Primary Use: Designed for exterior decking, fencing, and outdoor construction applications where corrosion resistance is critical, including use with pressure treated lumber, ACQ treated wood, and exterior commercial builds.
- Ultra Guard exterior coating rated at 2,000 hours for long term corrosion protection
- Quickcutter™ thread drives fast with strong holding power
- Built for exterior commercial and residential applications where standard coatings fail
- Designed to withstand harsh outdoor conditions without premature rusting or coating breakdown
Unlike standard exterior screws typically rated up to 1,000 hours of continuous salt spray and built with a single Type 17 point, Quickscrews Exterior Decking and Fencing screws combines 2,000-hour corrosion-resistant Ultra Guard coating with a proprietary Quickcutter™ thread. This design features a Type 17 point with an added groove on the shaft that acts like a tap—cutting threads while clearing wood dust for faster, low‑torque driving into even the hardest of woods without pre-drilling and significantly reducing splitting.
