HECO-TOPIX-plus, flange head, full thread

Diameter, d [mm]: 8,0 | Length, l [mm]: 100 | Size of recess: T-40 | Material: Stainless steel A2, self-colour | Packaged quantity: 50

The HECO-TOPIX-plus Flange head screw is specially designed for wood construction applications. It features a larger head diameter and is able to transfer considerably higher loads, due to the increased clamping surface. In addition, the amount of required fastening points is significantly reduced. The part-threaded version features shank ribs, which reduce the driving torque and ensure a tension-free connection. Easy and quick insertion is enabled by the optimally formed thread pitch. Further, the patented HECO-TOPIX-plus tip ensures a reduced splitting of timber, and allows a quick processing without pre-drilling and sinking.

HECO-TOPIX-plus T Solar

Length, l [mm]: 240

The HECO-TOPIX-plus-T Solar in A2 stainless steel ensures a long-lasting and economical mounting of solar brackets on over-rafter-insulated roofs. The HECO-TOPIX-plus-T Solar features two patented wood threads with the same pitch. They guarantee a fixation at defined intervals, where the secondary thread fixes the counter batten and all the loads are transmitted via the thread directly into the rafters. The HECO-TOPIX-plus-T Solar screw is quick and easy to use without predrilling thanks to the patented "TOPIX" tip. The tip also prevents any risk of the counter batten splitting; meaning installation is quick and clean. With the screws flange haed, the roof hook or solar system fitting can be screwed flush and securely to the wood to form a connection that lasts.

HECO-TOPIX-plus Therm

Diameter, d [mm]: 8,0 | Length, l [mm]: 200 | Packaged quantity: 50

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. Compared to conventional fastening applications the HECO-TOPIX-plus Therm provides advantages in handling and material costs. In combination with the HECO-TOPIX-plus CombiConnect it forms an additional system for the efficient on-rafter and facade 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.
