Product information

HECO 8 x 300 Countersunk Head Double Thread Silver Zinc Steel HD-40

HECO Schrauben Screws and Fasteners

Model |

8mm

Finish |

Silver Zinc

Purpose |

Secondary Thread Countersunk Head

Description |

The double-threaded screw HECO-TOPIX-plus Therm is specially made for the processing of pressure-soft insulating materials. With its two threads it enables offset-mounting, where the counter batten is fixed by the secondary thread. Wind suction or compressive loads are taken solely by the thread in the counter batten, and are transferred directly into the rafters. This prevents the impressing of the counter batten into the insulation.

Here, the occuring shear loads are taken by a combination of shear block and the HECO-TOPIX-plus CombiConnect. This system requires significantly less fastening points compared to conventional solutions.

Benefits |

Pressure forces are conducted directly into the rafters through the under-head thread

Increased load capacity thanks to the under-head thread

Can be used for common insulation materials

HECO-TOPIX tip does away with the need for pre-drilling, reduces the risk of the wood splitting and enables narrow edge and centre distances.

PerfectPitch: Optimal thread pitch for every screw length. Perfect performance for any wood application.
