The internal threaded anchor RG M I is made of zinc-plated steel. The internal threaded anchor is a systems accessory for various fischer mortar cartridges or injection mortars. Application with pre-portioned mortar cartridges is especially cost-effective for individual fixings. During mounting with the resin capsule, set the RG M I through rotating and hitting motions with a hammer drill. The capsule is destroyed during the setting process, which mixes and activates the mortar compound. During mounting with injection mortars, the internal threaded anchor is pushed into the drill hole manually by lightly rotating it. The various mortars bond the entire surface of the RG M I with the drill hole wall. The internal threaded anchor can be removed when surface-flush and is, for example, mainly suitable for temporary fixings such as for machines in internal areas.
