Streamline large-scale livestock fencing and utility grid projects with the industrial strength of Milwaukee® 9 Gauge Galvanized Staples. Purpose-built to handle harsh outdoor environments, these high-performance heavy-wire fasteners are ideal for securing high-tensile woven wire, barbed wire, and field fencing to treated wood posts, as well as binding heavy copper grounding wires firmly to utility poles. Each staple is layered with an advanced hot-dipped zinc-aluminum galvanized coating, delivering elite corrosion resistance that consistently exceeds the baseline performance of standard Class 3 galvanized hardware to eliminate premature rust failure and wire degradation.The structural geometry of these staples is optimized for extreme holding power and rapid tool feeding. They feature a unique diamond crown shape that arches smoothly over thick gauge lines and small plastic protective moldings without crimping or pinching the wire. Below the crown, the staple legs are engineered with a dual-retention system: sharp divergent tips that spread outward upon entering wood grain to form a mechanical lock, combined with aggressive surface barbs and a specialized adhesive coating. This multi-layered retention engineering vastly increases pull-out resistance over standard smooth staples. Perfectly bound in a durable tape collation string for seamless compatibility with automated utility fencing staplers, these professional-grade fasteners are available in three distinct lengths (1-1/2", 1-3/4", and 2") to match various wood densities and wire gauges.
