Description
Finished in RAL 7035 Light Grey, the PanelPro™ HP25-SD self-drilling hoarding screw fixes panels directly to metal framework up to 3mm thick, replacing the sharp point of HP19 and HP25 with a drill point while keeping the same discreet colour-matched wafer head.
The self-drilling point removes the separate pilot-drilling step, speeding installation on steel and aluminium frames where HP19 and HP25 would need pre-drilling.
HP25-SD completes the PanelPro™ system alongside the PanelPro™ HP19 19mm hoarding screw in RAL 7035 Light Grey and the HP25 25mm screw - match the self-drilling point to metal frames and the self-tapping points to timber, all in the same RAL finish.
Drill at speed and ease off as the wafer head seats to avoid stripping the metal thread, and brush away swarf immediately to protect the powder-coated finish. Maximum metal thickness 3mm - pre-drill thicker sections.
Colour-Matched for a Professional Finish
RAL 7035 Light Grey is a pale neutral grey for clean modern hoardings and signage. Matching the fixing head to the panel keeps large runs looking uniform and hides the fixings against the graphic.
PanelPro™ HP25-SD 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-SD is suitable for:
- Panels fixed to steel and aluminium hoarding frames
- Steel track and stud stitching (drywall / MF ceilings)
- ACM / Dibond® composite panels on metal carriers
- Aluminium sub-frames and steel box frames (no pre-drill)
- Sheet metal fixing up to 3mm (MDT 3.0mm)
Typical fixing centres: 300mm - 450mm (subject to panel size and wind loading).

Frequently Asked Questions
Do I need to pre-drill with these self-drilling screws?
No. PanelPro™ HP25-SD drills its own hole and forms the thread in one pass through sheet metal up to 3mm. Beyond 3mm, pre-drill the section first.
What can these fix panels into?
Metal framework - proprietary steel and aluminium hoarding systems, steel track and stud, aluminium sub-frames and box frames - up to 3mm thick. For timber frames, use the self-tapping HP19 or HP25 instead.
Do these match printed panel colours?
Yes. The powder-coated wafer head is colour matched to industry-standard RAL 7035 Light Grey so fixings sit discreetly against printed graphics.
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
Colour-matched fixings only work if the colour is right and lasts. That is why we powder coat all our coloured hoarding screws in-house to exact RAL specifications.
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 self-drilling screws:
- Scratch resistant
- Rust resistant
- UV resistant
- Weather resistant
- Colourfast
Other PanelPro™ HP25-SD Colour Options
PanelPro™ self-drilling hoarding screws are available in 40 colour-matched RAL finishes to align with printed hoarding graphics and panel systems.

Recommended applications
The self-drilling member of the PanelPro™ range, engineered for fixing printed hoarding panels, ACM graphic boards and composite panels directly to metal framework. The self-drilling point bores its own hole and forms the thread in a single pass through sheet metal up to 3mm - no pre-drilling - while the low-profile colour-matched wafer head keeps fixings discreet against printed graphics.
Ideal where hoarding uses proprietary steel or aluminium frames rather than timber, and for stitching light-gauge metal track and stud. Drill at speed and ease off as the head seats; brush away swarf immediately to protect the powder-coated finish. Use with a variable-speed driver and PH2 bit.
Maximum metal thickness 3mm - pre-drill thicker sections. For fixing to timber frames, use PanelPro™ HP19 or HP25 self-tapping screws.
