Screw anchor FISCHER 522119, zinc-plated steel, M12 thread, Ø12 mm, length 100 mm, pack of 20

The fischer bolt anchor FAZ II K is a compact steel anchor designed for demanding fixings in cracked concrete. Made of zinc-plated steel, this version is intended for indoor applications and provides secure fastening of heavy loads such as railings, cable trays and consoles. The anchor has a nominal diameter of 12 mm, an overall length of 100 mm and an M12 thread; the required drill hole diameter is 12 mm. The low drilling depth reduces installation time and effort while the expansion sleeve transfers loads reliably into the concrete, ensuring high load-bearing capacity even at reduced embedment depths.

Advantages

The FAZ II K meets the latest assessment criteria (ETA) where tensile strengths are decisive, allowing fewer anchors to be used for equivalent loads. Variable anchorage depths for sizes in the M8–M16 range enable millimetre-accurate adjustment to the applied loads. A cap nut option provides a neat finished appearance and reduces the risk of contact injuries due to its rounded shape. The range includes an M6 bolt anchor with ETA assessment Option 1 for secure anchorings. International approvals support predictable safety and performance.

Suitable for

• Fixing railings and balustrades

How to use

Drill a hole with a 12 mm drill bit to the required embedment depth, clean the hole thoroughly of dust and debris, insert the bolt anchor and tighten the nut to expand the sleeve against the concrete. Tighten to the torque specified by the manufacturer or applicable design guidelines to achieve the required load-bearing performance.

Usage recommendations

Use appropriate drilling and personal protective equipment. Verify substrate condition and required embedment depth before installation. For critical or structural applications refer to the ETA documentation and national regulations for design values and required spacing, edge distances and torque settings.
