Durable construction made to stand up to the rigors of environmental changes without breaking or bending. These heavy-duty fence staples are designed to attach welded or woven fence mesh to wooden posts. They're also commonly used to attach insulation and to fasten suspended ceilings to wood framing using wire. Formed from heavy 9 ga wire, these fence staples provide strong holding power. The galvanized coating has superior rust- and corrosion-resistant properties. We recommend you use these staples for exterior applications and treated lumber.
