Fischer Fixings Metal Cavity Wall Fixings, 10mm fixing hole diameter

The Fischer HM metal cavity wall fixings come with metric screws and are suitable for board building materials with a thickness of 3 mm to 50 mm. Having an expanding arm on the metal fixings gives you a large supporting surface allowing a higher load bearing capacity.

Can be removed and refitted several times because of the metric internal thread
Claws on the edge of the fixing penetrate the board material, preventing the fixing from rotating and thus ensuring a secure installation
