Screw Anchor Fischer 564628 20 pcs 173 mm Steel M16

The Fischer bolt anchor FAZ II Plus is a steel screw anchor for high-demand anchoring tasks in concrete and masonry. Designed for use in cracked and non-cracked concrete as well as suitable masonry substrates, it provides immediate load-bearing capacity after installation. The product is available in sizes compatible with M16 thread connections and is supplied in packs (20 pieces) with a length of 173 mm, making it suitable for structural fixings such as railings, cable trays and consoles as well as for certain dynamic applications like pumps and conveyor systems.

Advantages

The FAZ II Plus enables faster and easier installation by eliminating the need for drill hole cleaning for sizes M8–M24, and multiple approvals for concrete classes and masonry widen its range of applications. The recent ETA assessment increases the verified tensile strengths, reducing the number of required fixing points. For diameters M16–M24 the ETA confirms suitability for dynamic loads, and related approvals and test reports also attest to fire resistance and long service life. The anchor can absorb high seismic loads (performance categories C1 and C2) for M10–M24 and offers variable anchorage depths for precise adjustment.

Suitable for

• Anchoring railings and handrails
• Mounting cable trays and electrical supports
• Fixing consoles, brackets and structural connections
• Applications with dynamic loads (lifting platforms, conveyor belts, pumps) for M16–M24
• Seismic-resistant fixings in performance categories C1 and C2 (M10–M24)

How to use

Drill the hole to the required diameter and depth according to the approval and select pre-positioned or push-through installation as appropriate. Insert the FAZ II Plus anchor and apply the specified installation torque; the cone bolt will pull into the expansion sleeve and set the anchor once the preset torque is reached. For series installations use approved setting tools (e.g., FABS or FA-ST II). When seismic requirements apply, use the filling disc FFD to fill the annular gap. For dynamic-load applications, apply the recommended dynamic set and inject suitable mortar (compressive strength ≥ 50 N/mm²) into the dynamic set after installation (examples: FIS V Plus, FIS EM Plus, FIS HB or FIS SB).

Usage recommendations

Follow the product approval guidelines (ETA and other test reports) for substrate, diameter and embedding depth. Use the recommended installation tools and injection mortars for dynamic applications. Do not exceed specified torques and observe service-life and fire-resistance requirements stated in the technical documentation.
