Purpose-Built Hurricane Shutter Anchors: Designed specifically as hurricane shutter anchors for securing storm panels, shutter tracks, and hurricane protection hardware. Ideal for homes in high-wind and coastal regions. Reusable 1/4"-20 Internal Thread for Seasonal Installation: Features a reusable 1/4"-20 machine thread, allowing bolts to be removed and reinstalled every hurricane season without damaging the anchor or wall. Lead-Zinc Expansion Design for Concrete and Brick: Two-part lead–zinc alloy expansion body engages tightly inside concrete, brick, block, or masonry when activated using the included setting tool, creating a secure mechanical lock. Works with Storm Panels, Shutter Tracks & Exterior Hardware: Perfect for storm panel bolts, shutter rails, exterior brackets, AC cage mounts, and other hurricane shutter systems. Compatible with most 1/4"-20 hurricane shutter bolts. Corrosion-Resistant Alloy for Coastal Weather: Made from corrosion-resistant lead-zinc alloy that withstands salt air, moisture, and extreme weather, ensuring long-lasting reliability in hurricane-prone coastal environments. Built for hurricane season and engineered for shutter systems. Party Animals Hurricane Shutter Anchors are purpose-built to secure storm panels and hurricane shutter tracks to concrete, brick, and masonry surfaces. Unlike generic concrete anchors, these expansion anchors are optimized specifically for hurricane protection applications and seasonal installation cycles. Each anchor uses a lead–zinc alloy expansion shell that expands inside the drilled hole when activated with the included setting tool. Once expanded, the anchor forms a strong mechanical lock that resists vibration, wind pressure, and temperature changes. The internal 1/4"-20 thread allows shutter bolts to be installed and removed as needed—perfect for annual hurricane preparation and post-season storage. The threaded design prevents damage during repeated installation and helps maintain a secure, long-lasting anchor point. Ideal for storm shutters, hurricane panels, shutter tracks, exterior brackets, and other hurricane mounting hardware. With excellent corrosion resistance against salt air and coastal humidity, these anchors are built to perform in harsh weather environments. Package Includes: 50 × 1/4"-20 lead-zinc expansion anchors 1 × matching setting tool (Bolts not included) Prepare your home for hurricane season with hardware made specifically for the job.
