FISCHER Thermax 8/160 M6 Thermal Insulation Wall Plug 45690

The Thermax 8/160 M6 tackles the challenge of fixing loads to external thermal insulation composite systems (ETICS) without creating a thermal bridge. Its conical head design allows flush mounting, and the galvanised M6 threaded rod provides corrosion protection for the metal component, making it a reliable choice for long-term exterior applications.

Highlights

• Thermal bridge free: conical head and plastic body reduce heat loss at the fixing point
• Through-fixing method with M6 thread for secure attachment of light to medium loads
• Approved for use in concrete, solid brick, perforated brick, and aerated concrete
• Galvanised steel threaded rod for corrosion resistance
• ETA-12/0070 approval confirms performance for ETICS applications

In daily use

Installation is straightforward: drill an 8 mm hole to a depth of at least 170 mm, then set the anchor using a standard drill and an M6 wrench or socket. The anchor body is made of high-quality nylon, providing durability and resistance to weathering. The usable length of 160 mm accommodates typical insulation thicknesses, while the total anchor length of 180 mm ensures a secure embedment in the base material.
