Drop-in anchor for secondary attachments on porous surfaces, e.g. pumice, lightweight or aerated concrete. Zinc-plated steel
  • Can be used in various base materials such as PB2/PB4 autoclaved aerated concrete, perforated brick, pumice or lightweight concrete.

  • The fixing is driven in until flush without pre-drilling in PB2 autoclaved aerated concrete.

  • Easy installation.

  • For use in pre-positioned installation.

  • The W-MG 8 metal fixing, in conjunction with the M8 hanger bolt, conforms to the requirements of the TRGI (German Technical Guidelines for Gas Installations). Item 3.3.7.2 of these guidelines stipulates the requirements for laying the inner pipes: "Pipe fasteners must be fire resistant. The supporting parts of pipe fasteners must be made of non-flammable materials."

  • Wood and chipboard screws can be used.
Proof of Performance
  • Fire resistance: F30, F60, F90 and F120 (anchoring base: ≥ Vertically perforated brick HLZ 12, hollow sand-lime brick ≥ KSL 12, ≥ aerated concrete, strength class 4)

  • Exposure to fire according to DIN 4102-2:1977-09 (uniform temperature time curve)

VVVVAAABBB
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
VVVVAAABBB
005710 20 (1 space between the 10 and the 20)

Example 3: Flat washer with an internal diameter of 6 mm:
VVVVAAABBB
