Can You Get A4 Stainless Steel Collated Nails? A2 vs A4 Explained
It is a question we are seeing more often:
Can you get A4 stainless steel collated nails for nail guns?
The short answer is no – A4 stainless steel collated nails are not generally manufactured as a standard available option. For collated strip nails and coil nails, A2 stainless steel is the stainless option normally available to trade users.
This can be confusing, especially if you are working on an outdoor, coastal, cladding, fencing or cedar project where corrosion resistance matters. A4 stainless steel exists as a material grade, but that does not mean every type of fixing is made in A4, especially when it comes to collated nails for pneumatic and cordless nail guns.
At The MTK Group, we supply collated fasteners for a wide range of trade applications, so we understand why customers ask the question. The important thing is knowing what is actually available, what is suitable for the job, and when A2 stainless steel is the right choice.
Why Are People Asking for A4 Stainless Steel Nails?
A4 stainless steel is often associated with harsher environments.
It is commonly requested where corrosion resistance is a key concern, such as marine environments, coastal areas or applications exposed to high levels of moisture. Because of this, many people assume that A4 is automatically the best option for any outdoor fixing.
That assumption is understandable.
If you are fixing cedar cladding, fencing, garden buildings, shingles, external timber or treated timber, you want a fastener that will not rust, stain the timber or fail too early. So it makes sense that customers search for A4 stainless steel nails.
The issue is that loose fixings and collated fasteners are not always manufactured in the same grades.
You may be able to find A4 stainless steel in some screws, bolts or specialist loose fixings, but that does not mean the same grade is available in collated nails for nail guns.
A4 Stainless Steel Collated Nails Are Not a Standard Option
When customers ask for A4 stainless steel strip nails or coil nails, they are often looking for something that is not generally available in the collated nail market.
This includes requests such as:
- A4 stainless steel collated nails.
- A4 stainless steel strip nails.
- A4 stainless steel coil nails.
- 34 degree A4 stainless steel nails.
- A4 stainless nails for nail guns.
In practical terms, collated stainless steel nails are normally supplied in A2 stainless steel, not A4.
This is especially relevant for users looking for stainless steel 34 degree nails. If you need stainless steel 34 degree nails for a nail gun, the available stainless option is generally A2 stainless steel strip nails.
Looking for 34 Degree 50mm Stainless Steel Strip Nails?
If you are looking for 34 degree 50mm stainless steel strip nails, the practical route is usually A2 stainless steel rather than A4.
The key details to check are the nail length, collation angle, shank type, nailer compatibility and whether the timber or exposure level calls for stainless steel.
For example, if you are using a 34 degree first fix nailer and need a 50mm stainless strip nail, the question should not only be “Can I get A4?” It should be:
- Is A2 stainless steel suitable for the application?
- Is 50mm the correct length for the timber?
- Does the collation angle match the nailer?
- Is the shank type right for the level of hold required?
- Is the timber likely to stain if the wrong fixing is used?
These checks will usually get you to the right fastener much faster than searching for an A4 collated nail that is not normally available.
A2 Stainless Steel Is the Standard Collated Option
A2 stainless steel is widely used for outdoor timber and general external applications where corrosion resistance is needed.
For many outdoor timber, fencing, shed manufacturing and cladding applications, A2 stainless steel collated nails are the practical and appropriate collated option.
They are commonly used for:
- External timber work.
- Cedar cladding.
- Timber fencing.
- Garden buildings.
- Sheds and summerhouses.
- Shingles.
- Outdoor joinery.
- General construction where stainless steel is required.
A2 stainless steel gives better corrosion resistance than bright or standard galvanised nails and helps reduce the risk of rust staining in suitable applications.
For most outdoor timber projects where collated nails are being used, A2 stainless steel is the stainless grade customers should expect to find.
A2 vs A4: What Is the Difference?
Both A2 and A4 are stainless steel grades, but they are not the same.
A2 stainless steel is a common stainless grade used across many general outdoor and construction-related fixing applications. It offers good corrosion resistance and is often suitable for timber work where the fixing needs to perform externally.
A4 stainless steel offers higher corrosion resistance and is often associated with more aggressive environments, such as marine or highly corrosive settings.
That is why A4 is often specified or searched for when the job involves coastal exposure, salt spray or long-term moisture risk.
However, the key point for collated nails is simple:
A4 may exist as a stainless steel grade, but A4 stainless steel collated nails are not generally manufactured as a standard nail gun fastener.
So if you are looking for stainless steel nails for a nail gun, A2 is usually the correct available option.
What About Cedar?
Cedar is one of the main reasons customers ask for stainless steel nails.
Because cedar contains natural extractives, the wrong fastener can react with the timber and cause staining. This is why stainless steel is normally recommended for cedar shingles, cedar cladding, cedar fencing and similar applications.
For collated nail gun use, A2 stainless steel nails are commonly used for cedar applications.
The key is to make sure the nail is not only stainless steel, but also right for the tool and the job. That means checking the collation angle, length, shank type, diameter and finish before ordering.
A nail can be stainless steel and still be wrong if it does not match the nailer.
Why AI Search Results Can Be Misleading
One reason this question is becoming more common is that some AI-generated search responses suggest that A4 stainless steel collated nails are available.
This can send customers looking for a product that does not exist in the standard collated nail market.
The confusion usually comes from mixing together two separate facts:
A4 stainless steel is a real material grade.
Collated stainless steel nails are available.
But that does not mean A4 stainless steel collated nails are available.
For trade users, this can waste time and create frustration. You may spend time searching for 34 degree A4 stainless steel strip nails, only to find that suppliers cannot source them because they are not a standard manufactured option.
That is why it is always worth speaking to a specialist fastener supplier before spending too long searching for a product that may not exist in the format you need.
What Should You Use Instead?
If you are looking for A4 stainless steel collated nails, the best next step is usually to identify the application first.
Ask:
- What timber are you fixing?
- Is it internal, sheltered, external or highly exposed?
- Is the job near the coast or in a marine environment?
- Is the timber cedar or another reactive species?
- What nail gun are you using?
- Do you need strip nails or coil nails?
- What length and collation angle do you need?
For many outdoor timber, cedar, garden building and cladding applications, A2 stainless steel collated nails will be the practical available option.
For very harsh marine or highly corrosive environments where A4 has been specifically specified, it may be worth checking whether a different fixing method is required, such as a suitable loose A4 fixing rather than a collated nail gun fastener.
Do Not Guess the Fastener Specification
When stainless steel nails are needed, it is important not to choose based on grade alone.
A stainless nail still needs to match the tool and application.
Before ordering, check:
- Nail length.
- Diameter.
- Shank type.
- Collation angle.
- Collation type.
- Tool compatibility.
- Timber type.
- Exposure level.
- Quantity required.
For example, a customer asking for 34 degree 50mm stainless steel strip nails needs more than just “stainless steel”. The nails also need to suit the nailer, feed properly, drive cleanly and provide the right level of hold in the timber.
This is where speaking to a supplier who understands both fasteners and tools can prevent wasted time.
Final Thoughts
A4 stainless steel collated nails are not generally manufactured as a standard available option.
If you are searching for A4 stainless steel strip nails, A4 coil nails or 34 degree A4 stainless steel nails for a nail gun, the available stainless option will usually be A2 stainless steel collated nails.
For many outdoor timber, cedar, fencing, cladding and garden building applications, A2 stainless steel is the practical and commonly used choice.
The most important thing is to match the fastener to the tool, timber and exposure level, rather than relying on grade alone.
