KBRM 10,5 Aerated concrete screws

Aerated concrete screw (10,5 mm) for heavy loads

  • The Sormat KBRM (10.5 mm) is a fast, easy-to-use aerated concrete screw with a nano coating for porous materials.
  • The coarse-threaded aerated concrete screw is designed for push-through installations in porous base materials, such as light or aerated concrete blocks. The longer and thicker screw enables deeper installation, which improves its grip on the base material.
  • The thread-cutting tips of the aerated concrete screws make them self-tapping.
  • The profile of the shaft makes installation simpler and lighter and reduces the required installation torque.
  • The longer and thicker aerated concrete screw enables the installation of loads that are up to three times greater.
  • The screws are equipped with T40 drive and their minimum installation depth is 160 mm.
