FISCHER screw anchor FAZ II Plus M8 x 75 mm zinc-plated steel, for brick and concrete, pack of 50

The FISCHER screw anchor FAZ II Plus M8 x 75 mm is a zinc-plated steel bolt designed for reliable fixing in brick and concrete. Supplied with a pre-assembled large washer, these anchors are suitable for through-fixing and demanding anchoring tasks in construction and renovation. The variable anchorage depth and proven expansion sleeve enable secure load transfer into the substrate and flexible installation options.

Advantages

The FAZ II Plus GS anchors include a special pre-assembled washer that simplifies alignment when fixing steel components with elongated slots and reduces installation effort. Washers with a larger outer diameter provide a greater bearing surface, enabling use in wood construction where increased support is needed. Installation is quicker and easier since drill hole cleaning is not required for sizes M8–M24. Expanded approvals for a range of substrates, including various concrete grades, steel fibre concrete and solid sand-lime brick, broaden application possibilities. A recent ETA assessment increases permissible tensile loads, often reducing the number of required fixing points. Additional test reports confirm high fire resistance, and an independent assessment indicates service life up to 120 years for suitable conditions. Variable anchorage depths allow millimetre-accurate adjustment to applied loads.

Suitable for

• Through-fixing of metal profiles and plates to concrete and masonry
• Heavy-duty anchoring in cracked and non-cracked concrete
• Applications requiring pre-assembled washers for components with slots
• Construction and renovation projects that need durable, long-term fixings

When it may not be suitable

The FAZ II Plus M8 anchor is designed for solid substrates such as concrete and solid masonry; it is not intended for use in hollow or perforated blocks without additional measures or suitable sleeve anchors. For very thin base materials or substrates with insufficient thickness to achieve the required embedment depth, this anchor may not provide the necessary load capacity.

Key specifications

• Anchor type: screw anchor with expansion sleeve
• Material: zinc-plated steel
• Nominal thread size: M8
• Anchor length: 75 mm
• Required drill hole diameter: 8 mm
• Suitable substrates: concrete, solid brick, steel fibre concrete, solid sand-lime brick
• Installation types: pre-positioned and through-fixing (push-through); limited stand-off installation under conditions
• Variable anchorage depth for millimetre adjustment

How to use

Drill the required 8 mm hole to the specified depth in the chosen substrate, remove loose debris if necessary, and position the anchor either pre-positioned or push-through depending on the application. Tighten the bolt to the prescribed installation torque so the cone is drawn into the expansion sleeve and the sleeve expands against the drill hole wall. Set the anchor in accordance with the applicable approval and torque values. For components with slots, the pre-assembled washer facilitates alignment before final tightening.

What to consider before purchase

• Ensure the substrate is solid (concrete or solid masonry) and able to achieve the required embedment depth
• Confirm drill hole diameter of 8 mm and available installation space for a 75 mm anchor
• Check required load capacities and whether M8 thread size meets fastening needs
• Verify that through-fixing or pre-positioned installation fits the application

Usage recommendations

Use the FAZ II Plus anchors where durable, approved load-bearing fixings are required in concrete and solid masonry. Follow the approval and torque specifications for secure installation and consult technical documentation for specific load values and fire design requirements.
