MZ dowel 6x40. Quantity in package: 100 pcs. 9640MZ

Safe fastening in virtually any material

The MZ 6×40 expansion plug works reliably both in dense, solid building materials and in perforated bricks or other structures with voids. Thanks to four‑sided expansion it provides a stable and durable connection even under high loads – it does not pull out, does not pop out, and does not loosen.

Designed from high‑quality polyethylene, it is flexible, ageing‑resistant and halogen‑free, which means a lower risk of toxic gas emission in case of sudden heating – important when installing in confined spaces or near electrical installations.

For the installer – simplicity and universality

There is no need to select different plugs for different substrates. This single model fits screws with a diameter of 3–4.5 mm – i.e., most commonly used set screws and flat‑head screws. Simply drill a hole 6 mm in diameter and 50 mm deep – the plug’s expansion does the rest. The anchoring depth is exactly 40 mm, making the installation predictable.

The absence of a flange makes it easy to insert into a hole even in hard‑to‑reach locations. It does not jam, the edges do not catch – resulting in less frustration and faster installation.

For the end user – maintenance‑free durability

You don’t have to worry about loosening after a few years. Polyethylene retains its flexibility even with temperature and humidity changes. The plug is not brittle, does not crack, and does not corrode. It is a connection that works just as well after 10 years as it did at the first tightening.
