Fischer 50542 NA 8 x 40 Cavity Plugs (Pack of 50)

Conquer Hollow Walls

When installing shelves, mirrors, or light fittings on plasterboard or hollow blocks, traditional friction plugs are practically useless. There simply is not enough solid material for them to grip onto.

The Fischer NA series is specifically engineered for these tricky cavity environments. When you drive your screw in, the plug is forced to expand, folding and spreading out behind the board to create a large, secure load-bearing surface.

Engineered from Premium Nylon

Cheap plastic wall plugs turn brittle, snap during installation, or deform under temperature changes.

Fischer uses high-quality nylon for these cavity plugs. This gives you the practical advantage of extreme durability. They won't shatter when tapped into a tight hole and will maintain their grip safely over years of changing room temperatures.

Anti-Spin Reliability

One of the most annoying issues when fixing into plasterboard is the plug spinning in the hole as you try to tighten the screw.

To combat this, the NA 8x40 plug features integrated anti-rotation lugs. These small fins bite into the surrounding plasterboard or masonry, holding the plug completely still so you can drive your screw home perfectly tight.

Easy and Versatile

Supplied in a handy pack of 50, you have plenty of fixings for medium-to-large interior projects.

They require a standard 8mm drill bit and are fully compatible with regular wood and chipboard screws. Whether you are a professional shop fitter putting up lightweight displays or a DIYer hanging heavy picture frames, these plugs provide an effortless, reliable hold.
