Description
Oxide red is a muted, earthy red with deep roots in structural steel and agricultural metalwork. These 13mm x 4.2mm hex head self-drilling tek bolts in RAL 3009 Oxide Red are powder coated to match the dull, iron-influenced red used across agricultural steel frames, industrial cladding rail systems and heritage-referenced structural metalwork where a recessive, natural red-brown tone has been specified on visible fixing points. On a steel surface in this colour, a bright zinc hex head reads as a cold, metallic intrusion against a tone built around natural warmth and earthy depth.
The self-drilling Tek point cuts directly into light-gauge steel up to 3.0mm thick without pre-drilling, removing a step from installation on cladding rail and purlin fixing work. The hex head washer face spreads clamping load across the steel substrate, and the 1/4" hex drive is compatible with standard impact drivers and hex socket nut runners for fast, controlled installation.
These bolts are designed for steel-to-steel fixing applications only. For timber, plastic or composite panel substrates, the flange head self-tapping range is the correct specification. On agricultural steel frames, industrial unit cladding rails, structural steelwork and sheet metal fabrication in oxide red colour schemes, these hex head tek bolts provide a fast, secure connection with a colour-matched head.
RAL 3009 Oxide Red
RAL 3009 Oxide Red takes its character from iron oxide pigment, the same source that gives traditional red primer, agricultural building cladding and Victorian structural steelwork their distinctive earthy warmth. On steel structures this colour is a natural fit: agricultural steel frame buildings, barn and rural industrial cladding rail systems, heritage conservation steelwork and contemporary architectural projects referencing industrial material traditions are all contexts where oxide red appears on structural metalwork and where colour-matched fixings are part of the specification.
The muted, brown-influenced tone of RAL 3009 means that precise fixing colour matching matters more than it might initially appear. A fixing that reads too bright, too clean or too grey against this earthy surface each produces a different but equally visible mismatch. Each bolt head is powder coated to the exact RAL 3009 Classic standard, producing a head that carries the same natural, iron-influenced warmth as the metalwork it sits within.
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
Is RAL 3009 Oxide Red the same as red oxide primer on steel structures?
RAL 3009 takes its name and character from iron oxide pigment, the same base used in traditional red oxide primer. It reads as a very close match to cured red oxide primer and the red-brown tone common on agricultural steel cladding and structural steelwork. It is not an exact match for every primer product on the market as primer colours vary between manufacturers, but RAL 3009 is the closest standard RAL Classic specification to traditional red oxide and the colour most commonly specified to match these surfaces.
Do these bolts require pre-drilling?
No. The self-drilling Tek point cuts its own hole and forms the thread as it is driven into the substrate, removing the need to pre-drill. These bolts are rated for light section steel up to 3.0mm thick. For substrates thicker than 3.0mm, a different fixing specification is required.
Can these be used on timber or plastic substrates?
No. These hex head self-drilling tek bolts are designed for steel-to-steel applications only. For timber, plastic or composite panel substrates, the RALfixings flange head self-tapping range is the correct product.
How quickly can you deliver?
RAL 3009 Oxide Red 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 exists to give contractors and specifiers access to colour-matched visible fixings without the compromise of bright zinc heads on exposed metalwork. Every fixing in the range is powder coated in-house to exact RAL Classic colour standards, with consistent batch-to-batch colour accuracy across every pack size.
The electrostatic powder coating process deposits a fine layer of thermoset pigment onto the bolt head, which is then cured under heat to form a hard, permanently bonded shell. This finish outperforms wet paint across every measurable category: adhesion, hardness, chip resistance, UV stability and colour consistency across production runs.
Benefits of powder coated hex head tek bolts:
- Scratch resistant
- Rust resistant
- UV resistant
- Weather resistant
- Colourfast
Other Colour Options
These 13mm x 4.2mm hex head self-drilling tek bolts are available in over 60 colour-matched RAL finishes for cladding, roofing and exposed steel metalwork.

Recommended applications
Designed for fixing cladding rails, purlins, and light steel framing to structural steel substrates. The powder-coated hex head matches your panel or cladding RAL precisely, eliminating visible bright metal fixings on exposed metalwork. The self-drilling point removes the need for pre-drilling in light gauge steel.
At 13mm, these bolts are ideal for thin sheet metal connections and light-gauge steel framing where a short fixing length is required. The 1/4" hex drive (6.35mm) is compatible with standard impact drivers and hex socket nut runners.
Not recommended for timber or plastic substrates — use our flange head self tapping range for non-steel applications.
