These Tolsen 18GA brad nails are designed for use with standard pneumatic, electric, or battery-powered nailers, making them a versatile choice for various fastening tasks. Each nail measures 1.25 x 1.0 mm with a small 2 x 1.25 mm head, which helps the fastener blend into the wood for a cleaner finish. Constructed from galvanized steel, these nails are treated to resist corrosion, ensuring they remain stable over time. They come in packs of 5,000 pieces with a length of 40mm, providing enough supply for larger projects where a discreet and secure hold is needed.
