Description
Olive brown is a deep, earthy tone that sits at the intersection of brown and khaki. These 25mm x 4.2mm flange head self tapping screws in RAL 8008 Olive Brown are powder coated to match the warm, yellow-influenced brown used across agricultural buildings, industrial cladding and heritage-referenced architectural panels where a grounded, natural brown has been specified. On a surface in this colour, a zinc or grey fixing reads as a cold, industrial intrusion against a tone built around warmth and organic depth.
The 25mm length provides the thread engagement needed where the substrate carries depth behind the panel face. Timber batten hoarding frames, composite panels with a backing layer and exposed installations subject to wind loading all require a screw that passes through the panel and bites firmly into the frame below. The 25mm is the correct specification for these conditions.
The flange head distributes clamping force across a wide bearing footprint, preventing the point loading that narrower head designs apply to the panel skin. On ACM sheet, Foamex and rigid composite boards this prevents dimpling and surface stress at the fixing point. The Pozi PZ2 recess drives positively at installation torque with minimal cam-out, keeping the head surface and powder coat intact after fixing.
A 60° self-tapping thread and AB point cut directly into light-gauge steel and sheet metal frames without pre-drilling, and pull cleanly through softwood timber battens with strong holding power in both substrate types.
RAL 8008 Olive Brown
RAL 8008 Olive Brown is a mid-depth brown with a warm yellow-green undertone that gives it an earthy, organic quality distinct from the red-influenced warmth of copper brown or the darker, cooler tones of the deeper RAL browns. The olive influence places it in the same natural material territory as weathered timber, dried grass and sun-baked earth, which is why it has been a long-standing specification colour on agricultural steel buildings, rural cladding systems and industrial structures where a warm, unobtrusive brown is the correct finish for the surrounding landscape context.
While demand for RAL 8008 has shifted over recent years as architectural palettes have moved toward darker, more dramatic naturalistic tones, it remains a regularly specified colour on existing building stock, maintenance and refurbishment projects, and new builds in rural and agricultural contexts where continuity with established colour conventions is part of the brief. Each screw head is powder coated to the exact RAL 8008 Classic standard, with consistent colour across every pack for both new installation and maintenance work.
The yellow-green undertone in olive brown makes standard brown fixing specification unreliable on this colour. A fixing that sits too red or too dark reads as a different brown family entirely against the warmth and olive quality of RAL 8008, which is why matching to the RAL Classic standard rather than approximating the colour is the correct approach.
All RAL colours in the RALfixings range are held in stock for immediate dispatch without special order lead times on live project schedules.

Frequently Asked Questions
How does RAL 8008 Olive Brown differ from RAL 8004 Copper Brown and RAL 8011 Nut Brown?
RAL 8004 Copper Brown carries a strong red-orange influence that gives it a terracotta warmth distinctly different from the yellow-green undertone of RAL 8008. RAL 8011 Nut Brown is darker and cooler, with a richer, more chocolate-influenced depth. RAL 8008 Olive Brown sits between the two: warmer and more yellow-influenced than nut brown, but without the red-orange character of copper brown. If your panels read as a warm, mid-depth brown with a khaki or olive quality rather than a red or dark chocolate tone, RAL 8008 is the correct specification.
When should I use 25mm screws instead of 19mm?
The 25mm length provides additional thread engagement for thicker substrates, deeper timber battens and double-skin panel assemblies. Where the 19mm version suits single-skin sheet metal connections, the 25mm delivers extra grip and pull-out resistance when the screw needs to pass through the panel face and reach solidly into the frame behind.
Can these be used to fix hoarding panels to timber frames?
Yes. The 25mm length and self-tapping AB point thread make these screws well suited to fixing panels to the timber battens and stud frames used on construction hoarding. The flange head distributes clamping force across a wide footprint to hold the panel flat, while the extra length provides firm engagement into the timber behind.
How quickly can you deliver?
RAL 8008 Olive Brown is held in stock. Most orders dispatch next working day on a tracked 24-hour service. Larger volume orders typically ship within 3 to 5 working days.
Powder Coated Screws
RALfixings gives contractors and specifiers access to colour-matched visible fixings without painting screws on site or accepting a tone that does not match the panel system. Every screw in the range is powder coated in-house to exact RAL Classic colour standards, with consistent batch-to-batch accuracy across every pack size.
The electrostatic powder coating process deposits a fine layer of thermoset pigment onto the screw head, which is then cured under heat to form a hard, permanently bonded shell. This finish outperforms wet paint in adhesion, hardness, chip resistance, UV stability and colour consistency across production runs.
Benefits of powder coated self tapping screws:
- Scratch resistant
- Rust resistant
- UV resistant
- Weather resistant
- Colourfast
Other Colour Options
These 25mm x 4.2mm painted flange head self tapping screws are available in over 60 colour-matched RAL finishes for hoarding panels, signage and visible metalwork.

Recommended applications
Designed for fixing ACM panels, composite cladding, and timber facade boards to timber battens and structural substrates. The powder-coated head matches your panel RAL precisely, eliminating visible bright metal fixings against the facade surface.
Pre-drilling recommended for hardwoods over 20mm density. The flange head spreads clamping force across a wider footprint, reducing surface pitting and preventing pull-through on thinner sheet materials.
Not recommended for fixing into steel framing — use our self-drilling range for steel substrates.
