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.
Pro Tip: When nailing roofing felt in cold weather, warm the felt slightly before fixing if you can, as cold felt is more brittle around the nail head and more likely to tear under wind load before the next layer goes on.
Galvanised large head clout nails are used across roofing, drylining, and general construction wherever a sheet material needs a positive, tear-resistant fix. Roofers use them to secure felt underlays on pitched roofs, fixing laps and edges to rafters and battens. Drylining contractors use smaller sizes to nail plasterboard to timber studwork and ceiling joists. They are also used in garden and agricultural applications where a wide-head fixing is needed into soft or fibrous boards.

Not suitable for: Not suitable for applications requiring heavy duty corrosion protection in permanently wet or coastal environments, where stainless steel fixings would be more appropriate. Not designed for hardwood where pre-drilling would be required.
Select the nail length based on the material thickness and the substrate below. For roofing felt, a 20mm or 25mm nail is typically sufficient to fix through the felt and into the batten or rafter. For plasterboard, match the nail length to the board thickness and studwork depth. Drive nails straight and firm — the large head should sit flush against the surface without punching through the material.
Space fixings according to the material manufacturer's recommendations and any applicable guidance under Eurocode 5 for the service class. At laps and edges of roofing felt, closer nail spacing reduces the risk of wind uplift before the next layer is applied.
Select the correct nail length for the material thickness and substrate depth.
Position the nail at the fixing point, holding it perpendicular to the surface.
Strike firmly and squarely with a hammer, driving the nail in a single controlled sequence.
Check that the large head sits flush against the material surface without tearing through.
Space fixings at the intervals specified for the material or application.
At roofing felt laps and edges, use closer spacing to resist wind uplift before the felt is overlaid.
What is the difference between large head clout nails and standard clout nails?
Large head clout nails have a significantly wider diameter head than standard clout nails. This spreads the clamping load over a greater surface area, which prevents soft or fibrous materials like roofing felt and plasterboard from tearing around the fixing point. Standard clout nails have a smaller head and are better suited to harder or denser materials where tearing is less of a concern.
Are these clout nails suitable for external roofing applications?
Yes. These nails are galvanised to provide medium duty rust protection, making them suitable for outdoor and exposed roofing applications including fixing felt underlays to rafters and battens. They conform to Eurocode 5 service class 2, which covers applications exposed to occasional wetting. For permanently wet or coastal environments, stainless steel fixings would offer greater long-term corrosion resistance.
These clout nails are manufactured to a 3.00mm shank diameter across all lengths and feature an extra large diameter flat head. The galvanised finish provides medium duty corrosion resistance suitable for outdoor and service class 2 conditions as defined under Eurocode 5. The consistent shank diameter and head geometry ensure predictable performance when driven by hand into timber, battens, and sheet materials.
