Description
Multiwall Polycarbonate Fasteners (2-inch) are heavy-duty screws with neoprene washers designed to securely attach 16mm (5/8-inch) multiwall polycarbonate panels to framing materials. These longer fasteners provide the proper penetration depth needed for thicker multiwall structures while preventing leaks and panel damage. The washer seals against moisture penetration while allowing for proper thermal expansion and contraction in large-scale installations.
ShapesPlastics' 2-inch fasteners are engineered specifically for 16mm triplewall and multiwall polycarbonate sheets, with the correct length to penetrate through the thicker panel structure and secure it to wood or metal framing without over-compression. The hex head design allows for easy installation with a standard drill or driver. Self-drilling point eliminates the need for pre-drilling in most applications. Essential for commercial greenhouses, large patio covers, industrial skylights, and heavy-duty roofing applications where thicker panels are required for superior insulation and strength.

Frequently Asked Questions
How many fasteners do I need per panel?
Space fasteners 12-16 inches apart along all edges and across any intermediate supports. For 16mm panels used in commercial or heavy-duty applications, proper spacing is critical due to higher wind and snow loads. A standard 4ft x 8ft panel requires approximately 20-24 fasteners. Always follow manufacturer specifications and local building codes for your specific application.
Will these work with 6mm, 8mm, or 10mm panels?
No, these 2-inch fasteners are specifically designed for 16mm multiwall polycarbonate panels. Using fasteners that are too long on thinner panels can cause over-compression and damage. For 6mm panels, use our 1-inch fasteners. For 8mm or 10mm panels, you'll need intermediate length fasteners. Always match fastener length to your panel thickness.
What makes 16mm panels different from thinner panels?
16mm multiwall panels typically have triple-wall or more complex internal structures, providing superior insulation (higher R-value) and greater strength for large spans and heavy loads. They're commonly used in commercial greenhouses, large structures, and applications requiring maximum energy efficiency. The thicker structure requires longer fasteners like these 2-inch screws to properly secure them to framing.
Do I need to pre-drill holes?
The self-drilling point works for most wood and metal framing. However, for thick panels like 16mm, pre-drilling with a slightly oversized hole is often recommended to allow for greater thermal expansion in large panels. This is especially important for commercial installations with long panel runs. Never overtighten - the washer should compress slightly but not pull the panel down tight.
