Description
James Hardie Hardie Stainless Steel Screws 4.2 x 40mm are purpose-designed premium fixings developed specifically for installing Hardie® Plank and Hardie® VL Plank fibre cement cladding systems onto timber battens.
When you are investing in high-performance fibre cement cladding, the fixings matter just as much as the boards themselves. Cheap screws can corrode, snap under load, strip during installation, or fail over time - especially in exposed external environments. These genuine Hardie screws are engineered to provide the strength, reliability and long-term durability required for professional cladding installations.
Manufactured from corrosion-resistant stainless steel and fitted with a precision Torx drive head, these screws deliver cleaner installation, stronger holding power and a far more dependable finish compared to standard timber screws.
Why These Hardie Screws Are Worth It
-
Designed specifically for HardiePlank systems
Properly matched to Hardie® Plank and Hardie® VL Plank cladding installations for reliable long-term performance.
-
Premium stainless steel construction
Excellent resistance against corrosion, rust and weather exposure, making them ideal for external cladding applications.
-
Far stronger than cheap generic screws
Fibre cement cladding places different demands on fixings than standard timber projects. These screws are engineered for the job properly.
-
Torx drive for cleaner installation
Reduces cam-out, improves grip and makes installation faster and more controlled, especially during large-scale installs.
-
Secure fixing into timber battens
Provides excellent holding strength without compromising the cladding boards.
-
Ideal for visible or concealed fixing applications
Suitable for both HardiePlank overlap systems and Hardie VL Plank systems depending on installation method.
-
Trusted by professional installers
Widely used by cladding contractors, developers and timber frame installers who want reliable fixings that will last as long as the facade itself.
Why Quality Cladding Screws Matter
With fibre cement cladding, failures almost always start at the weak points — and poor-quality fixings are one of the biggest causes of future problems.
Low-grade screws can lead to:
- rust staining,
- fixing head failure,
- loose boards,
- movement issues,
- premature corrosion,
- and expensive remedial work later on.
These genuine Hardie stainless steel screws are designed to avoid those problems and provide a fixing solution that matches the lifespan and performance of the cladding system itself.
For installers working on premium residential builds, commercial projects, garden rooms or specification work, using the correct fixing is simply the smarter long-term choice.
Compatible With

Help with my new garage roof!
Trade Warehouse could not have been more helpful. They very patiently guided a roofing newbie through all of the stuff I would need to do the job and provided helpful tips along the way. It's rare to find a company offering such a fantastic level of customer service as standard. I would highly recommend them and will certainly use them again.

Garden Storage
My contractor (Charlie Keep) recommended you to me so I could order the materials online for delivery direct to my home. These were for a project to construct a Garden Storage Area. The materials were perfect and the whole process was simple and slick with materials delivered on time and very well packaged. Charlie has since completed the project & I am very happy with the outcome.
