ejotherm® STR H

Applications

Screw fastener for countersunk and surface fixed installation
for timber and some steel substrates

• For timber and steel (max. 0.75 mm) substrates
• For all insulation boards
• For countersunk and surface fixed installation

Properties

• Fastener, consistent of a galvanized steel screw, included washer and EPS sealing plug.
• Countersunk Installation - EJOT STR principle with ejotherm STR cap for homogeneous surfaces and even rendering - quick and easy without milling dust
• No drilling necessary
• Surface fixed Installation using ejotherm STR plug
• Permanent contact pressure
• Premounted screw for quick installation
• 100% setting control: the countersunk Installation of the washer indicates safe anchorage
