Hex Head Fibreglass Assembly Screws 14g x 65mm (Qty 50)

The Hex Head Fibreglass Assembly screws 14g x 65mm are a specialised fastening solution for fibreglass and polycarbonate roofing and cladding. Each pack contains 50 hex head screws designed to hold translucent sheeting firmly to its support structure, with the length and gauge to suit most fibreglass assembly jobs.

The hex head design allows efficient torque application with standard power tools, so the screw drives home with control and a tight, reliable fit. The 65mm length and 14 gauge thickness give the reach and strength needed for the crest of a profiled sheet and the timber or steel framing beneath.

These screws are built for outdoor, exposed use, with corrosion-resistant materials that stand up to weathering. They are the kind of fastener you fit once and forget, which matters when the roof is already up and a failed screw means a leak.

What You Need To Complete The Job

These screws fix Topglass 2400GSM and other fibreglass or polycarbonate sheets to the frame. Lay a foam tape along the supports first to stop the sheet creaking, and keep a washer or seal where the fixing passes through the sheet. The screws and tapes are in the Polycarbonate Accessories and Screws categories.

Frequently Asked Questions

What are these screws for?

They fix translucent fibreglass and polycarbonate sheeting to its supporting frame. The length and gauge are sized for the crest of a profiled sheet and the timber or steel purlin below.

Why a hex head?

The hex head lets a drill driver apply high torque without slipping, which gives a tight, controlled drive and reduces the chance of stripping the head. It is the practical head shape for outdoor sheeting work.

How many screws are in a pack?

Each pack contains 50 screws, which suits a small to medium project. For a larger roof, allow about six screws per sheet at the recommended crest spacing and order enough packs.

Do they suit both timber and metal frames?

They are a general fibreglass assembly screw, so they work with the common framing materials used for sheds, skylights and walkways. Match the screw length to the depth of the profile and the frame for the best bite.

Will they corrode outdoors?

They are made from corrosion-resistant material designed for exposed, outdoor use, so they resist weathering and hold their fixing strength over time. That is essential for a fastener that is inaccessible once the roof is finished.
