Clout Nails Extra Large Head – Galvanised

Large head clout nails are the go-to fixing for jobs where the material needs to stay put without tearing through. The extra large diameter head spreads the clamping load across a wider surface area, which is exactly what you need when nailing down roofing felt, fixing plasterboard, or securing any soft or fibrous sheet material that a standard nail head would pull straight through. These are hot dip galvanised to give medium duty rust protection, making them suitable for outdoor and exposed applications without the nail staining or corroding around the fixing point.

These nails conform to Eurocode 5 and meet service class 2 requirements, so they are an appropriate choice where a specified or code-compliant fixing is needed. At 3.00mm shank diameter across the full size range, they drive cleanly without splitting or deforming the surrounding material, and the consistent shank means they work reliably in both hand and hammer applications.

Where Large Head Clout Nails Get Used

The most common use is roofing felt, where the wide head is essential to hold the felt securely at laps and edges without tearing. On a windy site, a standard nail head gives felt very little to grip against — the large head makes a real difference in how long that felt stays down before the next trade comes along. Plasterboard fixing is another typical application, particularly on studwork ceilings and partitions where a positive, flat fix is needed across the board face.

Choosing the Right Size

The range runs from 13 x 3.00mm through to 50 x 3.00mm, covering everything from lightweight felt tacking to heavier sheet fixing. As a general guide, roofing felt laps and edges are typically fixed with 20mm or 25mm nails, while thicker boards or battened applications may call for 30mm to 40mm. The 50mm option gives extra bite where you need to fix through a thicker substrate into a batten or rafter below.

Packs are available in 500g, 1kg, and 2.5kg sizes across TIMbag and TIMtub formats, so you can buy to suit the job — a small bag for a repair, or a tub for a full roof. The TIMtub is a practical choice on site where the pack gets opened and closed repeatedly over the course of a job.
