These Milwaukee 1-3/4" 9 Gauge Galvanized Staples are intended for use in attaching wire fencing to wood fence posts, as well as securing copper grounding wire to utility poles. These staples are zinc-aluminum coated hot dipped galvanized to ensure corrosion resistance. Our staples have barbed and coated divergent staple legs for increased holding power in materials. The diamond crown design allows for use with larger wire sizes and small plastic moldings.
