### Product Overview The FWA 10x80 ZP Bolt Anchor Fastner Fischer (Pack of 50) is an exceptionally robust mechanical through-bolt anchor designed to deliver dependable holding power in demanding construction environments. Manufactured by Fischer, the world-renowned authority in fixing systems, this mechanical anchor with precise dimensional metrics of 10x80 is supplied in an economical pack of 50 pieces, providing contractors and structural engineers with a high-performance, cost-effective solution for structural fastening in non-cracked concrete and dense natural stone substrates. Combining precision manufacturing with an optimized expansion design, the FWA series ensures rapid installation and superior load transmission. ### Key Engineering Features & Advantages * **High Load-Bearing Capacity:** Engineered with an innovative expansion clip that evenly distributes radial pressure across the borehole walls, enabling impressive tensile and shear load endurance. * **Optimized Edge & Spacing Distances:** The refined geometry of the expansion sleeve minimizes internal concrete stresses during expansion, permitting installation closer to slab edges and adjacent anchors. * **Rapid Through-Fixing Installation:** Designed for push-through installation, allowing the anchor to be inserted directly through the pre-drilled fixture into the concrete base, significantly reducing labor time. * **Corrosion-Resistant Finish:** Protected by a high-quality zinc-plated (ZP) treatment that shields the carbon steel body from oxidation and rusting in dry internal building environments. * **Pre-Assembled Convenience:** Each bolt anchor comes pre-assembled with a matching hexagonal nut and washer, streamlining on-site workflow and eliminating missing components. ### Technical Specifications & Material Properties Constructed from high-tensile carbon steel, the Fischer FWA bolt anchor is processed through advanced cold-forming and heat-treatment techniques to achieve optimal mechanical ductility and strength. The dimensional specification 10x80 denotes the metric thread diameter and anchor length, precisely calibrated to accommodate specific fixture thicknesses and embedment depths. The protective zinc plating complies with rigorous industry corrosion standards, ensuring stable mechanical performance over extended service lifespans. The anchor sleeve is stamped with distinct size markings, allowing inspectors and building officials to quickly verify proper anchor sizing even after installation is complete. ### Application Areas & Use Cases Thanks to its exceptional mechanical grip and structural reliability, the FWA 10x80 ZP Bolt Anchor Fastner Fischer (Pack of 50) is widely utilized across diverse civil engineering and commercial building applications: * **Structural Steel Erection:** Securing base plates for steel columns, mezzanine support beams, and industrial storage racking systems. * **Metal Staircases & Handrails:** Fastening heavy-duty steel stair stringers, guardrails, balustrades, and platform gratings in public and industrial facilities. * **Facade & Canopy Substructures:** Attaching metal bracketry for exterior wall cladding, entrance canopies, and architectural shade structures. * **MEP & Industrial Installations:** Mounting heavy cable tray brackets, pipe support frames, ventilation ducting hangers, and electrical switchgear enclosures. * **Safety & Security Fixtures:** Anchoring perimeter security gates, bollards, crash barriers, and warehouse guard rails. ### Installation Guide & Best Practices For maximum structural safety and rated load performance, follow Fischer's recommended installation procedure: 1. **Drilling the Borehole:** Using a hammer drill and a carbide-tipped masonry bit matching the nominal diameter of the anchor, drill the hole perpendicular to the surface through the fixture to the required embedment depth. 2. **Cleaning the Hole:** Remove all drilling dust and concrete debris from the borehole using compressed air, a blow-out pump, or a wire brush. Thorough cleaning ensures the expansion clip grips solid concrete rather than loose dust. 3. **Inserting the Anchor:** Drive the FWA bolt anchor through the attachment fixture into the borehole using a hammer until the washer and nut sit firmly against the fixture's surface. 4. **Applying Torque:** Using a calibrated torque wrench, tighten the hexagonal nut to the manufacturer-specified installation torque. As the nut turns, the tapered bolt head is drawn upward into the expansion sleeve, expanding it firmly against the concrete walls to create an immovable mechanical interlock.
