Product Description

The fischer Termofix B is a corrosion-protected screw fixing for fixing pressure-resistant insulation boards in sheet metal up to 1.5 mm thick. The insulation fixing comprises a holding disc made from polypropylene and a prefitted drill screw. The screw is protected against corrosion with a DeltaSeal coating and offers permanent security. The Termofix B is set in the Push-through installation with a cordless powerdriver without pre-drilling. The prefitted screw saves time. The head is sealed with the locking ball against heat loss. The flexible head offsets the thermally induced tensions and prevents damage.
  • The prefitted screw shortens the processing time.
  • Higher corrosion protection for the screw thanks to the Delta-Seal coating. The means security for years to come.
  • An air column is created above the head by the locking ball. This reduces heat transmission.
  • The flexible head offsets the thermally induced tensions and prevents damage.
  • For very soft insulation materials, can be combined with the insulation discs DT 90, DT 110, DT 140.
