Sinsun Factory Direct: Premium Clout Nails for Roofing & Felt Applications

Sinsun is a professional clout nails factory that produces high-quality clout nails, also known as flat head clout nails, roofing clout nails, and clout fasteners. These nails are used for construction and roofing all over the world. Clout nails are short, strong fasteners with wide, flat heads that spread out pressure evenly to keep things from getting damaged. They ensure they stay in place. It is our goal to manufacture each nail with care, taking into account the issues contractors often face, such as loose fasteners, corrosion, and a lack of consistency in quality.This can lead to expensive rework.
What makes Sinsun different from other suppliers? We handle every part of the production process, from choosing the raw materials to checking the finished product. This cuts out the middlemen and lets us offer factory-direct prices without sacrificing quality. We offer our clout nails in a variety of sizes and materials, so you can find the right ones for your needs and climate. If you order in bulk, you can adjust the length, material, and surface treatment to suit your project.Many of our competitors can't do this.

Popular Classifications of Clout Nails

Clout nails come in a range of materials and sizes. Each serves a specific purpose. Here’s how we categorize them for our customers.

Copper Clout Nails

If you're doing high-end roofing or heritage work, copper clout nails are your best choice. These are commonly used for repairing slate roofs, cedar shingles, and clay tiles.This is because copper doesn't react to these materials the way steel does. Over time, old buildings gain charm. These are usually the only kind of fastener you can use on a listed building or conservation area. When you're putting on a roof that should last for a hundred years, it's imperative to not rust. The trade-off is cost; copper costs more than steel, but for the right project, nothing else will do.

Galvanised Clout Nails

This is what you do every day. A zinc coating on galvanized clout nails keeps them from rusting and corroding. When you need to attach roofing felt to wood battens, lay down underlayment, or tack down insulation board, these are what you reach for. Zinc layers can vary in thickness. For example, it could be electro-galvanized for indoor use or hot-dipped for outdoor use. From what I've seen, contractors who don't do not perform sufficient galvanization always regret it six months later when rust shows through. Sinsun uses a consistent zinc coating that covers the shank and head evenly, not just a quick wash that burns off in the nail gun.

Stainless Steel Clout Nails

Stainless steel is the right choice when you know corrosion won't happen. You should use these nails in places with salt air or constant moisture, like on the coast or in the ocean. When fixing metal roofing panels, it is also recommended to use stainless steel clout nails instead of steel nails that rust. This would cause galvanic corrosion between the two types of metal. Because they are more durable than regular steel nails, they penetrate straight into dense hardwoods without bending. The price is higher than galvanized, but for permanent structures, peace of mind is worth every penny.

Aluminium Clout Nails

Aluminium clout nails are the lightweight alternative. They’re commonly used for fixing aluminium flashing, cladding, and lightweight roofing materials where you want to avoid galvanic reactions. Because they’re non-ferrous, they won’t rust or leave stains. Additionally, they're softer than steel nails, making them easier to drive without splitting thin timber or delicate materials.It's common for gutter installers and cladding specialists to request these. Note that aluminum nails are softer than steel nails, so they're best suited for applications where shear strength isn't a major concern.

20mm Clout Nails

The standard length for attaching single-layer roofing felt to timber battens is 20mm, or about 3/4 inch. It's short enough that it won't go through thin plywood sheathing, but long enough to get a good grip on 12mm to 18mm wood. This size is also used to hold down insulation boards, vapour barriers, and synthetic underlayments. This is the size of the box you'll need for general roofing work.

Send inquiry Now

10mm Clout Nails

The smallest specialist is the 10mm clout nail, which is about 3/8 inch long. People use these to hold down thin materials like felt underlayment on shed roofs. They also fix carpet underlay, or secure down thin sheets of material where a long nail would pass through the back. They don't hold as well as longer nails, but for light-duty jobs where you need to be careful, they're perfect.

Common Uses for Clout Nails

1. Roofing Felt & Underlayment Fixing

Sinsun clout nails hold roofing felt and underlayment tightly to roof decks. Their very large flat heads spread pressure evenly, so the material doesn't tear or slip. These nails make a tight seal that keeps water out, lowering the risk of leaks and water damage. This is whether you're working on a home or business roof. Even on sloped roofs, they are easy to install, saving contractors time and effort on every job.

2. Slate & Tile Roofing (Copper & Stainless Steel)

Our CLOUT nails are suitable for lightweight metal roofing and siding panels. The sharp tip easily penetrates through metal and wood decks, and the flat head keeps the panels in place without hurting the surface. Galvanized and stainless steel options don't rust, so the fasteners last as long as the roof itself. A lot of contractors use these nails because they are strong and work with many different types of metal panels.

3. General Construction & Carpentry

Clout nails are a quick way to attach rigid insulation boards or vapour barriers to wood framing. The flat head keeps the material in place without tearing. A 20mm or 25mm galvanised nail has enough bite to hold it in place without breaking through the back of the sheathing. We often suggest stainless steel for foil-faced insulation so that it doesn't react to the foil in any way.

4. Heritage & Restoration Projects

Although small structures are exposed to the same weather as houses, people often forget about the quality of the materials.. For felt shed roofs, wood siding, and trim on the outside of the house, a galvanized clout nail is the most suitable choice. For most uses, the 20mm or 25mm size is just right. After one winter, I've seen too many garden buildings with rusty nail heads bleeding through the felt. The right galvanization stops that.

5. Underlayment for carpets and upholstery

The smaller 10mm and 12mm clout nails are suitable for holding down carpet underlayment or attaching felt to wooden furniture frames. The flat head keeps the material from pulling through, and the short length won't hurt the surfaces underneath that are already finished. It's not something everyone needs, but it's a must-have for flooring installers and upholstery shops.

How to Install Clout Nails SINSUN

Even people who aren't very skilled at DIY can easily install Sinsun Clout Nails. First, ensure that your material (felt, metal sheet, or board) is lined up well on the surface. To prevent the material from bending or breaking, hold the nail straight and don't angle it. Push the nail in until the head is level with the surface. Don't push too hard, though, because this can rip the thin materials. When putting down roofing felt, put nails 15 to 20 cm apart at the edges and 30 cm apart in the middle. For metal sheets, follow the manufacturer's instructions, which usually say to space them 10 to 15 cm apart. Use the right size of nail for your material at all times. If it's too short, it won't hold, and if it's too long, it could damage the surface below.

Guide to Choosing Clout Nails SINSUN

The right clout nail for your project and climate depends on what you're doing. If you live in a rainy or coastal area and need to roof your house, use galvanised or stainless steel clapton nails. Copper clout nails are the most appropriate choice if looks are paramount, like in heritage projects. If you're working with light materials or doing it yourself, 10mm clout nails are an excellent choice. You should use 20mm for heavier roofing and buildings. Aluminium clat nails are suitable for projects where weight is critical. If you're not sure, our team can help you choose the right nail to ensure your project lasts.

Real Customer Feedback

We collect real feedback from our customers across key clout nails markets—including France, Brazil, and Malaysia—to refine our products and ensure we meet local needs.

For a year now, we've been using Sinsun copper clout nails for listed buildings. The quality stays the same; there are no bent shanks or flaking heads. The copper gauge is the same as what we brought in from Belgium. We were able to bid more competitively on the large church roof job and still make a profit. This is because we got the price directly from the factory. Delivery to the site proceeded smoothly.

Geoffrey Sinclair, a roofer from Manchester, UK

My clients are on the North Sea coast. Standard galvanized nails don't work. Last year, I started selling Sinsun stainless steel clout nails, and the reviews were positive. It can handle salt air, and the head is big enough for roofing felt and cladding. Bulk packaging also makes it easier to store in my warehouse.

Peter De Vries (Building Supplies, Rotterdam, Netherlands)

Project: Adding insulation to old commercial roofsWe use thousands of 20mm galvanised clout nails every week to attach PIR insulation boards to wooden decks. Our pneumatic nailers work well with Sinsun nails, and the collation strips are always the same, so there are fewer jams. The real test came when we built a building with a green roof system. After a year, there were no corrosion problems. I'm now ordering pallet sizes.

New Build with Breathable Membrane ProjectWe switched to Sinsun hot-dipped galvanized clout nails for all of our battens and breathable membranes. The zinc coating is much thicker than the brand we used before. The nails go straight in, even into kiln-dried Irish oak, and after six months on the coast, they don't rust. The price from factory direct was also about 15% better than what our local store charged.

Frequently Asked Questions (FQA)

What is the difference between roofing felt nails and clout nails?

A: They're both the same thing. The old name for these nails is "clout nails," but the new name, "roofing felt nails," is more accurate. Both terms refer to nails with a big, flat head that are used to attach thin sheet materials, felt, and underlayment to wood.

Is it okay to use galvanized clout nails for copper flashing?

A: No. When you mix copper with galvanized steel, you get galvanic corrosion. The steel will rust very quickly. Use copper or stainless steel clout nails for copper roofing and flashing.

How big of a clout nail do I need for roofing felt?

A: A 20mm galvanized clout nail is the most common choice for a standard single layer of roofing felt on plywood or timber battens. Go up to 25mm or 30mm if you're going through thicker insulation or more than one layer of felt.

Do you have 316-grade stainless steel clout nails?

A: Yes. We have both 304 and 316 stainless steel clout nails in stock. 316 is the best choice for places with a lot of saltwater and high levels of chloride. You can choose either grade when you place an order with the factory.

Do copper clout nails cost more than regular nails?

A: Yes, if you want your project to last a long time, like natural slate, cedar shingles, or historic buildings. Copper doesn't rust, stain, or wear out like most modern building materials. Galvanized steel is usually enough for standard asphalt felt on a shed.

s it okay to use clout nails in a nail gun?

A: Yes, collated strips for pneumatic nailers come in a lot of different sizes of clout nails. Ask us which lengths and materials are available in collated form. For big roofing jobs, our bulk customers often like strip-collated clout nails because they are faster.

How can I keep clout nails from rusting after I put them in?

A: Begin with the right coating. The thick zinc coating on hot-dipped galvanized nails keeps them from rusting. Nails made of stainless steel and copper don't rust at all. Don't use electro-galvanized or bright finish nails if you live near the coast or in a place with a lot of humidity. They will rust quickly.

What's the difference between a felt nail and a clout nail?

A: Nothing. The words mean the same thing. Some places call them "clout nails," while others call them "felt nails" or "clout head nails." Both refer to the unique large flat head that keeps felt and membranes in place.

Do you sell aluminium clout nails for attaching aluminium flashing?

A: Yes, we make aluminium clout nails just for putting up aluminium flashing and cladding. Using aluminium nails with aluminium flashing takes care of any worries about galvanic corrosion.

Q: Is it possible to get special coatings or lengths?

A: As a factory, we can make custom orders for lengths that aren't standard, special coatings, and specific packaging. If you have a big project or need to keep making things, please get in touch with us and let us know what you need.
