### Product Overview The Chemical Fastner FTR 20x160 5.8Gr Fischer (Pack of 10) is a high-tensile, precision-engineered threaded anchor rod manufactured by Fischer to serve as the structural backbone of advanced chemical anchoring systems. Constructed from high-quality Grade 5.8 carbon steel with a protective zinc-plated (ZP) treatment, this chemical fastener with precise dimensional metrics of 20x160 is supplied in an economical pack of 10 pieces. Designed specifically for integration with Fischer injection mortars (such as FIS EM Plus, FIS Ep Plus, and FIS V Plus) and resin capsules, the FTR threaded rod provides structural engineers and contractors with an uncompromised load-transfer mechanism capable of sustaining heavy static and dynamic loads in concrete and masonry substrates. ### Key Engineering Features & Advantages * **Optimized Thread Profile:** Precision-rolled external metric threading ensures maximized interfacial mechanical interlocking with cured chemical resin matrices, delivering exceptional pull-out resistance. * **Stress-Free Load Transmission:** When installed with chemical mortars, the anchor rod adheres to the borehole wall without mechanical expansion forces, allowing for safe installations near concrete edges and close anchor group spacing. * **Chiseled Point Design:** Features a specialized 45-degree angled tip that facilitates smooth insertion into resin-filled boreholes and acts as a mixing blade when used with glass resin capsules. * **Certified Structural Performance:** Manufactured from certified Grade 5.8 carbon steel, guaranteeing predictable yield and ultimate tensile strengths essential for structural engineering calculations. * **Complete Pre-Assembled Set:** Each FTR rod is supplied complete with a high-strength hexagonal nut and a heavy-duty flat washer, ensuring immediate job-site readiness. ### Technical Specifications & Material Properties The FTR threaded rod is produced from premium carbon steel meeting ISO property class 5.8 specifications, which provides a minimum tensile strength of 500 N/mm² and a yield stress of 400 N/mm². The surface is treated with an electrolytic zinc plating (ZP) that creates a uniform protective barrier against oxidation and corrosion in dry interior environments. The designation 20x160 reflects the nominal metric diameter and overall rod length, carefully calculated to provide the exact embedment depth required for optimal chemical bonding while leaving adequate thread projection for fixture attachment. ### Application Areas & Use Cases When paired with Fischer chemical resins, the Chemical Fastner FTR 20x160 5.8Gr Fischer (Pack of 10) is the definitive fastening choice for high-consequence structural engineering projects: * **Heavy Steelwork & Foundation Anchoring:** Securing structural steel columns, industrial portal frames, pipe rack supports, and heavy timber posts to concrete foundations. * **Infrastructure & Civil Engineering:** Fastening bridge parapets, highway noise barriers, tunnel utility brackets, and heavy overhead signage structures. * **Industrial Machinery & Equipment:** Bolting down vibrating manufacturing machinery, hydraulic presses, cranes, and generator sets where dynamic fatigue resistance is required. * **Structural Retrofitting & Strengthening:** Installing steel ledger angles, bracketry for building seismic upgrades, and heavy facade support frames. * **Safety & Perimeter Installations:** Anchoring high-security perimeter fencing, crash bollards, bank vaults, and heavy industrial blast doors. ### Installation Guide & Best Practices To guarantee the maximum certified bonding strength of the chemical anchoring system, execute the following installation steps: 1. **Borehole Preparation:** Drill a hole to the required diameter and embedment depth using a rotary hammer drill. The borehole diameter must match the resin manufacturer's specification for the FTR rod size. 2. **Thorough Hole Cleaning:** This is the most critical step in chemical anchoring. Clean the borehole using a strict sequence: blow out twice with oil-free compressed air or a blow pump, brush twice with a Fischer steel wire brush, and blow out twice again. Any residual dust will act as a bond-breaking layer. 3. **Resin Injection:** Inject the appropriate Fischer chemical mortar into the cleaned borehole, starting from the very bottom and filling it to approximately two-thirds of its depth. 4. **Rod Installation:** Push the FTR threaded rod into the resin-filled hole with a slow, continuous twisting motion until it reaches the bottom of the borehole. Verify that excess chemical mortar beads out uniformly around the washer at the surface. 5. **Curing & Tightening:** Do not disturb or load the anchor rod during the resin curing period. Once the full curing time has elapsed, position the attachment fixture, apply the washer and nut, and tighten to the specified installation torque using a calibrated torque wrench.
