Dowel 6x41 with flange and screw 4.5x50. Quantity per package: 50 pieces. 9641MZKSZ

Universal Mounting in a Single Set

The CELO MZK 6 × 41 mm expansion plug with flange and dedicated screw 4.5 × 50 mm is a ready-to-use solution suitable for practically every type of substrate—from concrete and stone to solid brick, gypsum-fiber blocks, or chipboard. Thanks to four-sided expansion in solid materials and the bonding effect in perforated bricks and other structures with voids, the anchor maintains stability even under high dynamic loads. The set includes a plug made of high-quality polyethylene (halogen-free) and a galvanized screw with a countersunk head, ensuring both durability and corrosion resistance.

Advantages and Practical Tips

• Versatility – the only set needed for installation in concrete, natural stone, solid brick, lightweight blocks, and gypsum-chipboard panels.
• Four-sided expansion ensures even distribution of anchoring force, eliminating the risk of hole deformation and increasing pull-out strength.
• Flange prevents the screw from falling into the hole and increases the tightening torque—installers will appreciate the ease and reliability of installation.
• Compatibility – the plug works with many types and sizes of screws; the dedicated screw 4.5 × 50 mm is already matched in length and diameter.
• Weather resistance – polyethylene retains flexibility from –40 °C to +80 °C, ensuring the anchor does not lose its properties even under extreme temperature conditions.
• Halogen-free – the material does not emit toxic gases during a fire, which is crucial for electrical and photovoltaic installations.
• Easy installation – simply drill a hole with a diameter of 6 mm and a depth of at least 40 mm, insert the plug with flange, and tighten the supplied screw; the minimum edge distance is one plug length (≈ 41 mm).

Thanks to this design, installers can rely on fast and secure installation, while the end user receives a robust connection guaranteeing safety and long-term durability.
