IMC bolt anchor, stainless steel R, uncoated. Particularly suitable for fastening medium-heavy loads outdoors in uncracked concrete and dense natural stone. The K version, shortened by 2 cm, allows for savings in drilling effort and material costs. Installation is possible in both pre- and through-mounting, as well as easy hammering into the drill hole. When tightening the nut, the bolt pushes into the expansion clip, thus expanding against the borehole wall and ensuring secure hold. The bolt anchor is frequently used for fastening thin concrete components and in applications where loads are less critical. ETA-10/0169, European Technical Approval, Option 7 in uncracked concrete. Type K: Short version.
