ejotherm® STR H A2

Applications

Screw fastener for the corrosion resistant fixing of ETICS
with German DIBt approval

• For Fermacell boards, cement particle boards, wooden substrates and metal Frame
• For a corrsion-free fastening
• For countersunk and surface fixed installation
• For homogeneous surfaces
• With German DIBt approval

Properties

• Fastener, consistent of a A2 stainless screw with hardened drill point, included washer and an EPS sealing plug
• EJOT STR principle with ejotherm STR cap for homogeneous surfaces and even rendering - quick and easy without milling dust
• Countersunk installation in mineral wool insulation boards WAP-zg (type WV) in combination with ejotherm VT 2G
• No drilling necassary
• Surface fixed installation with ejotherm STR plug
• Permanent contact pressure
• 100% Setting control: the countersunk installation of the washer indicates safe anchorage
