Screw for thermal insulation, 55mm diameter, 8mm zinc die‑cast, for drilling through sheets up to 0.5mm thick. Quantity per package: 50 pieces. 955IPSZH

Quick installation without pre‑drilling

The 955IPSZH screw does not require drilling holes in plaster or insulation – the sharp drilling tip allows direct screwing even into AAC2 aerated concrete and thin sheets up to 0.5 mm. You do not need to mark points, you do not need to pre‑drill – just place and twist. This saves time at every stage of installation.

No thermal bridges and natural watertightness

Made of pressure‑cast zinc alloy, the screw does not conduct heat like steel. An integrated EPDM seal, permanently mounted under the head, conforms to the substrate surface and closes the through‑hole – preventing moisture or cold from penetrating into the façade interior. No additional sealing of the mounting point is required later.

For thin insulation – perfectly matched length

Specifically designed for insulation of 60 mm thickness (wood wool, peripheral boards), its 55 mm length does not exceed the insulation layer. It does not protrude, does not press on the substrate, and does not create mechanical “bridges”. It fits standard through‑holes of 8 mm diameter – the ones used for wall profiles or concealing strips.

TX25 drive and universal application

Operates with a cordless screwdriver equipped with a TX25 bit – it transmits high torque without risking head damage. It can be used to fasten profiles, protective strips, signs, lighting or motion detectors. Additionally – thanks to the hole in the head – it serves as a base for light fastenings with a Ø 3.5 mm screw.

Resistance to external conditions

The zinc alloy casting does not rust. The EPDM seal is resistant to UV, ageing and extreme temperatures – it does not crack or lose elasticity even after years of service. It does not need to be replaced. It does not need to be inspected.
