The eyebolt screw OES 12-160 matches optimally with the scaffold plug GR 14 for high pull out values in concrete, solid brick and natural stone. Markings on the eyebolt screw enable controlled screwing in and safe assembly. The eyebolt screw OES made of galvanized steel can also be screwed directly into wood. After removing the scaffolding and the eyebolt screw, the cover cap AK seals the remaining scaffold plug GR.
