Product Information

Full details

The STS NoMorePly External Render Board Screws are designed for professional contractors and DIYers needing a reliable, heavy-duty solution for fastening 12mm construction boards in external settings. These 38mm screws provide exceptional stability and corrosion resistance, ensuring a secure, render-ready finish for timber and steel frame projects. While they offer superior hold and convenience, users should note that they are specifically optimized for 12mm board thickness and may not be suitable for thinner or thicker non-specified materials.

Extended Product Information

FAQs

Are these screws suitable for internal use?

Yes, while designed for external render boards due to their corrosion resistance, they function perfectly for internal applications.

Can I use these on boards thicker than 12mm?

These screws are specifically engineered for 12mm construction boards. Using them on thicker materials may lead to insufficient thread engagement.

Do I need to pre-drill into steel frames?

The screws are designed for lightweight steel; however, if your steel gauge is heavy, a pilot hole may be required to facilitate entry.

What is the Ruspert coating?

Ruspert is a high-grade, three-layer ceramic/metallic coating that offers superior protection against rust and chemical corrosion compared to standard zinc plating.

How many screws are in a box?

Each box contains 250 screws, along with a compatible screwdriver bit.

Troubleshooting

Screw head sits proud (not flush)

Increase the depth setting on your drill or apply slightly more downward pressure while driving to allow the self-countersinking head to seat properly.

Screw spinning in the hole

This may occur if the frame material is too soft or pre-drilled incorrectly; ensure you are using the correct drive speed and not over-tightening.

Bit slipping out of the screw head

Ensure you are using the included screwdriver bit; if the bit is worn, replace it to maintain proper contact with the screw recess.

Pros and Cons

Pros

Excellent corrosion resistance via Ruspert coating
Flush finish thanks to self-countersinking design
Saves time by removing the need for pre-drilling
Includes a high-quality screwdriver bit in every box
Highly compatible with diverse framing materials including timber and steel

Cons

Optimized only for 12mm board thickness
Not intended for non-construction board applications
Limited to 38mm length, which may not fit all structural depth requirements

Setup, Compatibility & Care

To achieve the best results, ensure your timber or steel frame is clean and properly aligned before installation.

Drill Settings: If using an impact driver, use a lower torque setting initially to ensure you do not overdrive the screw past the flush point.
Bit Usage: Always use the provided screwdriver bit to match the screw head geometry perfectly, reducing the risk of cam-out.
Storage: Keep the screws in the original plastic box in a dry area to prevent premature environmental exposure before installation.
Compatibility: These screws are tested specifically for use with 12mm STS Construction Boards; ensure your board choice matches this specification for guaranteed performance.
