Using these DeWalt 23-gauge 1-1/2-inch pin nails is easy. First, make sure your pin nailer is compatible with 23-gauge nails. Load the nails into the nailer according to the manufacturer's instructions. When you're ready to start, position the nailer on the wood surface where you want to attach the trim or other material. Squeeze the trigger gently to drive the nail in. For best results, use a light touch and keep the nailer perpendicular to the surface. As for maintenance, keep the nails in a dry place to prevent rusting. If the nailer jams, follow the nailer's manual to clear the jam safely. And always wear safety goggles when using the nailer to protect your eyes from any flying debris.
