Galvanised metal discs supplied as a box of 100. Designed for use with screws to hold insulation to battens and assist with minor ceiling repairs.


Secure, long-lasting hold - with a large diameter head

The large diameter head spreads load across insulation and backer-board surfaces when used with screws, reducing the chance of pull-through. Galvanised metal construction offers a basic layer of corrosion resistance suitable for interior conditions.

A reliable fixing method for insulation and backer boards that keeps materials in place during handling and over time in dry rooms.

Ready for multiple jobs - thanks to the box of 100

Supply in a pack of 100 removes the need for frequent reorders on small and medium-sized jobs. The boxed format also makes it easier to store and transport on site.

Plenty of discs for several rooms or repeat repairs, helping maintain workflow without stopping to restock.

Suitable for internal repair work - with corrosion rating 1 guidance

A corrosion rating of 1 indicates suitability for clean, dry and low-humidity environments rather than exposed outdoor conditions. Galvanised finish provides basic protection but is not rated for harsh or damp locations.

Best used indoors where humidity is controlled, for example loft spaces, internal walls and ceilings, where longevity is adequate for typical interior applications.
