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 E
