What Size Screw for ICF Walls
Introduction
Ever stand on a jobsite wondering what size ICF screw to use? You’re not alone. Choosing the right fastener may seem minor, but it’s the difference between secure walls and frustrating callbacks. Contractors, builders, and distributors often struggle with Screw Size Options—too short and the grip is weak, too long and you risk damaging the block. Add in different Screw Material Types for ICF Blocks, and the choice gets even trickier.
