Powernail 18-Gauge Chiselpoint PowerStaples — Reliable, High-Hold Fastening for Flooring & Subfloor Applications When every layer matters, trust Powernail’s 18-gauge Chiselpoint PowerStaples to deliver secure, consistent performance. These staples are crafted from high-tensile galvanized steel with a chisel (flat) point to drive cleanly into wood or engineered subfloors. They feature a narrow ¼-inch crown that reduces surface scarring while still providing a firm grip under load. Features & Benefits Chisel-point design — slices through materials cleanly with less splitting or damage to the substrate. Narrow crown (¼") — minimizes visibility and surface disturbance while maintaining strong holding power. Corrosion-resistant galvanized steel — suitable for humid or moisture-prone jobsite environments. Versatile lengths available — commonly offered in lengths like 1-1/8", 1-1/4", 1-1/2", depending on thickness of substrate. Compatible with narrow-crown staplers — works with standard 18-gauge narrow-crown pneumatic staplers (including Powernail’s own 1845F, 1890U, and equivalents). High yield per box — ideal for large jobs where consistency and supply matter.
