Why Coloured Hex Head Tek Bolts Are the Smart Choice for Roofing

When it comes to roofing, speed, durability, and finish all matter. Our coloured hex head Tek bolts deliver all three — combining a self-drilling point, powder-coated finish, and watertight seal. Here's why they're becoming the go-to for professionals across the UK.

1. Built for Roofing and Cladding

Each Tek screw features a sharp, self-drilling tip that cuts into steel or timber with ease. No pilot hole needed. That means faster installs and fewer tool changes — perfect for roofing, wall cladding, and structural fixings.

2. Colour-Matched, Powder-Coated Heads

Choose from 14+ RAL colours to perfectly match your project. Each head is powder coated for a long-lasting, chip-resistant finish — no flaking, no fading, and no unsightly screw caps.

3. Sealed Tight with EPDM Washers

Each screw is fitted with a high-performance EPDM washer. This compresses under torque to create a watertight seal — protecting against leaks, rust, vibration, and thermal movement.

4. Stainless Steel and Bimetal Options

For maximum corrosion resistance, choose stainless steel tek bolts. For tougher substrates, go for bimetal: combining stainless steel heads with carbon steel tips for strength and longevity.

5. Built for Speed and Reliability

With reduced snapping, stripping, or capping, you’ll install more screws per day with less downtime — improving site efficiency and lowering total job cost.

6. Why Not Polytops?

Polytop screws crack, fade, and limit your options. Our coloured Tek bolts offer more lengths, more finishes, and no plastic caps. One-piece simplicity. Zero compromises.
