A Wall Anchor Kit including extra-long drive-in helical wall ties that are used as chemical-free structural connectors to secure a building’s facade to a wall that runs perpendicular to it. The 12mm diameter self-tapping ties are driven deep into masonry to form a mechanical connection that needs no cement, grout or resin, making them ideal for remedial use when working on heritage houses and ancient monuments.

The 910mm long12mm diameter structural ties have twice the mass of any other self-tapping helical wall ties of similar design or function.  They corkscrew into brick, block, limestone and concrete, when driven into an undersized pilot bore, to offer outstanding resistance to axial and shear loads

Manufactured from marine grade stainless steel (AISI 316) and with a cross sectional area of 29mm2, the 

  • No material compatibility issues on old houses or listed buildings having lime mortars
  • No installation temperature restrictions; can be used in freezing conditions
  • At least twice as strong in compression, tension and shear than alternative helical fixings
  • 8-10 times quicker to install than ties that are fixed using chemical bonded agents
  • Less disturbance to the structure than with any other deep pinning system

In addition to tying walls to cross walls and party walls, these versatile structural masonry anchor fixings are ideal for use on brick or stone buildings to secure quoins, tie thick or rubble-filled walls, pin masonry arches or to introduce vertical reinforcement to parapet walls. This wall anchor kit contains:

  • 10pcs long-series 12mm (1/2") diameter x 910mm (36”) long spiral wall connectors
  • 1m SDS masonry bit. Select 8mm (3/8”) for soft or medium strength masonry or 10mm (7/16”) for hard
  • A professional SDS adaptor that hammers the structural wall connectors into a pre-piloted masonry wall

This Thor Helical Wall Anchor Kit is made in Britain and protected under UK Patent No: GB 2439633.  For ease of application, safety considerations and to preserve the life of the long-drill bits we recommend that smaller drill bits are used to start the pilot holes
