100 Expansion Anchors M10 12mm for Climbing Holds / Climbing Wall / Boulder Wall
You use brass expansion anchors for fastening climbing holds to concrete walls.
- Internal screw thread M 10
- For cylinder head screw DIN EN ISO 4762 - M10 (DIN 912)
- For countersunk head screw DIN EN ISO 10642 - M10 (DIN 7991 )
These anchors are not according to the technical approval of fastening climbing holds to concrete. We inform you about this for legal reasons and exclude any liability for the use of these anchors. Nevertheless, we mention that these anchors are often used in practice to fasten climbing holds concrete walls.
First you drill a hole into the concrete wall, which has the same diameter as the outer diameter of the anchor (12 mm). Drilling depth: about 40 mm. Now the anchor is driven into the drilling hole with a rubber mallet. Then a M10 socket head screw is needed which is that long that the anchor spreads and wedges in the concrete wall.
It is recommendable to buy a few brass expansion anchors than originally needed, since most of the time one or two mistakes are made by non-professionals while assembling.
