10 x Corrugated Sheet Screws, Washer and Cap

Pack of 10 fixing screws, washers and caps for installing corrugated plastic sheets. Pack contains 2 inch (50mm) zinc plated screws with PVC strap washers and caps.

These are fastened through the ridge profile of the plastic corrugated sheets, and require predrilling of the sheets. When installing the screw needs to be tightened tight enough to create a seal, but not over tightened to deflect the sheet too much; the sheets are often supported with eaves fillers to prevent this or additional plastic spacers.
