Fischer letbetonskrue 8x90 - T/direkte montage u/forborring, undersaenket hoved, 50stk

The Fischer M-S expansion anchor is made of high-quality nylon for screws with a metric thread. This special anchor can be used in both pre-insertion and time-saving through-insertion installations. When the screw is tightened, the M-S expands and secures itself in the drill hole. The Fischer M-S expansion anchor is ideal for fastening handles, shutters, or downpipes in concrete, aerated concrete, solid gypsum boards, and all other solid and hollow building materials.

Advantages: The internal geometry of the M-S allows for the use of standard metric screws or threaded rods, enabling optimal adaptation to the application. The edge-free anchor sleeve allows for the necessary deep setting of the anchor below the plaster down to the load-bearing substrate to achieve maximum load capacity. Since the anchor only expands in two directions, the expansion forces can be directed parallel to the edge of the building material by rotating the anchor, allowing for smaller edge distances. The slim anchor geometry facilitates easy insertion of the anchor into the drill hole for quick and simple installation.

Applications: Handles, shutters, trellises, downpipes, spacer mounting, window brackets, grids.

Building materials: Concrete, hollow ceilings made of brick and concrete, sand-lime hollow blocks, sand-lime solid blocks, natural stone with dense structure, solid lightweight concrete blocks, solid bricks, solid gypsum boards, high-hole bricks, aerated concrete.

Functionality: The M-S is suitable for both pre-insertion and through-insertion installation. When the screw is tightened, the M-S expands in two directions, securely anchoring itself in the building material. The required screw length is determined by: anchor length + plaster and/or insulation thickness + component thickness + 1 x screw diameter. It is suitable for metric screws and threaded rods. To facilitate the easy insertion of screws and threaded rods, the thread should be chamfered.
