Specifications
Simpson Strong-Tie Trim-Head Deck Screws are built for clean, secure deck board installations with lasting holding power and a smooth finish. Featuring a square drive for slip-free engagement during installation, these screws are easy to drive and resist cam-out in both hand-driven and auto-feed systems. The trim-style head seats flush with the surface, creating a polished appearance ideal for visible decking surfaces.
A Type-17 point allows fast starts and reduced splitting and is paired with coarse lower threads to draw deck boards tightly against joists for superior pull-through strength. Designed with type 305 stainless steel for corrosion resistance, and a square hand-drive with painted heads, these screws are versatile and jobsite-ready.
Key Features:
- Trim-Style Head – Flush fit for a clean, finished deck surface
- Square Drive – Easy, secure driving with reduced slippage
- Type-17 Point – Fast starts with minimal splitting
- Coarse Lower Threads – Pulls boards tight to framing for a solid hold
- 305 Stainless Steel – for maximum corrosion resistance
