Description
Traffic purple is a bold, saturated colour that sits entirely outside the range of any standard fixing finish on steel. These 13mm x 4.2mm hex head self-drilling tek bolts in RAL 4006 Traffic Purple are powder coated to match the vivid, mid-tone purple used across branded steel structures, architectural feature metalwork and specialist installations where a strong purple has been specified on visible fixing points. On a steel surface in this colour, a bright zinc or grey hex head reads as a cold, flat intrusion against a tone built around chromatic confidence and visual impact.
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 architectural feature steelwork, branded steel structures, pipe identification systems and sheet metal fabrication in traffic purple colour schemes, these hex head tek bolts provide a fast, secure connection with a colour-matched head.
RAL 4006 Traffic Purple
RAL 4006 Traffic Purple is a pure, mid-tone purple with balanced red and blue components and no significant grey influence. On steel structures this colour appears across branded installations where purple is a primary brand colour, architectural feature metalwork where a bold chromatic tone has been deliberately specified, and pipe identification systems and equipment housings where purple is part of a recognised colour-coding standard. In all these contexts, purple is one of the colours most poorly served by standard fixing options: there is no zinc, grey or black hex head that reads as anything other than a mismatch against a saturated purple steel surface.
Each bolt head is powder coated to the exact RAL 4006 Classic standard, giving steel installations in this colour a fixing that sits within the surface rather than registering against it. On steel structures where hex head bolts are visible at regular fixing centres, that colour match is what holds the visual consistency of the metalwork across the full elevation.
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 4006 Traffic Purple differ from RAL 4007 Purple Violet on steel structures?
RAL 4006 Traffic Purple is a vivid, mid-tone purple with strong chromatic presence and no significant grey influence. RAL 4007 Purple Violet is considerably darker, with a deep blue undertone that pushes it toward near-black on steel structures in most lighting conditions. If your metalwork reads as a bold, saturated purple with clear colour presence, RAL 4006 is the correct specification. If the surface reads as a very dark purple that loses most of its colour character in shadow, RAL 4007 is the closer match.
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 4006 Traffic Purple 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.
