The SENCO FASTENING SYSTEMS A109809 is a 2,600-count assortment of 23 gauge galvanized micro pin nails designed for precision fastening in finish carpentry and millwork applications. Available in assorted lengths from 0.5 inches to 1 inch, these headless straight-collation pins drive cleanly with minimal surface disturbance. The galvanized finish resists corrosion, and the 23 gauge diameter reduces splitting risk in delicate materials. Finish carpenters and trim installers rely on this format when a visible nail hole would require filling or when thin stock would be compromised by a larger fastener. Standard tensile construction ensures consistent feed and drive performance in compatible pneumatic pin nailers.
These micro pin nails are intended for light-duty finish and detail work in residential and commercial construction. Typical applications include fastening small decorative trim, glazing bead, carved millwork, picture frame molding, and similar thin or fragile stock where leaving nearly no visible hole is a priority. The assorted length pack covers a range of material thicknesses in a single box, making it practical for trim crews working across multiple profiles on a single job.
Compatible with the Senco FinishPro10, Senco FinishPro11, Porter-Cable Pin100, and Accuset A100mp pneumatic pin nailers.
Installation is performed by finish carpenters using a compatible 23 gauge pneumatic pin nailer connected to a regulated compressed air supply. Verify the nailer manufacturer's recommended operating pressure range before use and adjust the compressor regulator accordingly. Keep the nailer magazine clear and the nose piece free of debris to maintain consistent drive depth. Disconnect the air supply before clearing jams or performing any maintenance on the tool.
