Self-Drilling Hex Screws 10x22mm (50 Pack)

The Self-Drilling Hex screws 10x22mm are the assembly fasteners for the Sunglaze aluminium joiners. They fix the aluminium cap down onto the base and secure the end closure to the joiner, creating the compression that lets the EPDM gaskets seal against the polycarbonate panels. Without them the joiner is just a loose collection of profiles.

The precision-ground self-drilling tip pierces architectural-grade extruded aluminium without pre-drilling, which keeps the assembly fast. The hex head gives maximum torque transfer from a drill driver, preventing cam-out and letting each screw be driven home precisely.

At 10 gauge and 22mm, the screw is sized exactly for the Sunglaze aluminium-to-aluminium connections. It provides the clamping force that keeps the whole joiner assembly rigid against wind uplift and thermal movement, and a corrosion-resistant finish keeps it clean over the life of the roof.

Specifications

Applications

• Fixing the Sunglaze cap to the base
• Securing the end closure to the joiner
• Assembling the aluminium joiner system

What You Need To Complete The Job

These screws assemble the Aluminium Sunglaze Cap onto the Aluminium Sunglaze Base and fix the Aluminium Sunglaze End Closure. The complete joiner set and the Sunglaze sheets are in the Sunglaze category.

Frequently Asked Questions

What are these screws for?

They are the assembly screws for the Sunglaze aluminium joiner. They lock the cap down onto the base and fix the end closure in place, creating the compression that seals the gaskets against the panels.

Do I need to pre-drill the aluminium?

No. The self-drilling tip pierces the extruded aluminium as the screw is driven, so there is no separate pilot hole. That keeps the assembly of a long joiner run quick.

Why a hex head?

The hex head lets a drill driver apply high torque without slipping off the head, which is important when driving into aluminium. It also reduces cam-out, so the screw drives home cleanly every time.

How many screws do I need?

Each pack contains 50 screws. You need one at each fixing position along the cap and at each end closure, so the number depends on the length of your joiner run.

Can these screws be used on timber or steel?

They are sized and tipped for the Sunglaze aluminium-to-aluminium connections. For fixing the base to timber or steel subframes, use the dedicated Sunglaze base fixing screws for the right substrate.
