The fischer screw fixing TermoFix 6H-NT is ideal for fixing pressure-resistant insulation up to 280 mm in wood and panel building materials. The screw fixing comprises a support disc made from polyamide with a prefitted fischer Power-Fast screw with approval. The minimal embedment depth of 30 mm ensures fast installation. The TermoFix 6H-NT is set flush to the surface in the push-through installation with a cordless powerdriver without pre-drilling. The head is them sealed with the screw plug. Optionally, the TermoFix 6H-NT can be countersunk with the fisher setting tool TSS. The insulation disk is then covered with a round cap.
