Description
The 25mm PanelPro™ HP25 hoarding screw in RAL 9005 Jet Black extends the HP19 platform for jobs that need more grip: thicker or multi-layer panels, deeper engagement into timber, and hoardings exposed to greater wind uplift. The low-profile colour-matched head keeps fixings invisible against printed graphics.
Where standard-length screws bottom out before reaching the frame, HP25 restores proper embedment - a cleaner, more reliable fix on double-skinned, battened or overclad panels.
HP25 sits alongside the PanelPro™ HP19 19mm hoarding screw in RAL 9005 Jet Black and the self-drilling HP25-SD in the PanelPro™ system, so you can match point type to the frame and length to the build-up without changing colour or head profile.
The fine-thread sharp point drives cleanly into timber and light-gauge steel, while the low-profile powder-coated head ensures a clean, discreet finish across large-format hoarding. Use a variable-speed driver with a PH2 bit and avoid overdriving.
Colour-Matched for a Professional Finish
The RAL 9005 Jet Black head - a deep true black, a top-selling contemporary fixing colour - is powder coated in-house to the exact RAL reference so it aligns precisely with panels and trims specified in the same colour.
PanelPro™ HP25 is available in 40 colour-matched RAL finishes, held in stock for rapid dispatch so contractors and procurement teams can source consistent fixings across full and multi-site installations.
Designed for Site Efficiency
PanelPro™ HP25 is suitable for:
- Thicker and multi-layer hoarding panels
- Wind-exposed and tall perimeter hoardings
- Battened, overclad and double-skinned build-ups
- ACM / Dibond® and Foamex boards on timber framing
- Deeper fixing into softwood site frames
Typical fixing centres: 300mm - 450mm (subject to panel size and wind loading).

Frequently Asked Questions
When should I use HP25 instead of HP19?
Step up to HP25 where the panel build-up is thicker, the frame timber is soft, fixing centres are wider, or the hoarding is tall or wind-exposed. The extra 6mm of thread gives greater embedment and withdrawal resistance. For standard single-skin panels, HP19 remains the go-to.
Can these be used externally?
Yes. PanelPro™ HP25 is suitable for external hoarding installations typical of UK construction projects. The powder-coated head is weatherproof, colour-fast and durable.
Do these match printed panel colours?
Yes. The powder-coated head is colour matched to industry-standard RAL 9005 Jet Black to help the fixings disappear into the panel for a clean, professional finish.
What are the delivery and lead times?
We hold stock across all 40 colours for quick next-day despatch on a tracked 24 service. Bulk or bespoke colour orders usually take around 3 - 5 working days.
Powder Coated Screws
At RALfixings we powder coat every coloured hoarding screw in-house to exact RAL specifications, because the smallest details make the biggest difference on a finished hoarding.
Powder coating electrostatically applies coloured powder to the fixing before curing it at high temperature, creating a hard, uniform layer that significantly outperforms painted finishes - durable, colourfast and built for site.
Benefits of powder coated hoarding screws:
- Scratch resistant
- Rust resistant
- UV resistant
- Weather resistant
- Colourfast

PanelPro™ hoarding screws are available in 40 colour-matched RAL finishes to align with printed hoarding graphics and panel systems.

Recommended applications
The 25mm companion to PanelPro™ HP19, engineered for fixing printed hoarding panels and ACM graphic boards to timber and light-gauge steel framing where extra length is needed - thicker or multi-layer panel build-ups, deeper embedment into softer timber, and hoardings under higher wind load. The low-profile wafer head and colour-matched powder coat keep fixings discreet against printed graphics.
The additional 6mm of thread over HP19 increases withdrawal resistance where panels are exposed to greater wind uplift or fixed at wider centres. Use with a variable-speed driver and PH2 bit. Avoid overdriving.
Fixing schedules for wind-loaded hoardings should be confirmed by the temporary works designer. For fixing panels to metal framework, use PanelPro™ HP25-SD self-drilling screws.
