Spax T-Star Plus Washer-Head Wirox Coated Screws - 6.0 x 200mm (Box of 16) 
Timco Corrugated Sheet Fixings are designed to fix plastic corrugated sheets to timber. The screws are coated in zinc for water resistance and come with a hinged cover cap to seal it to prevent water from entering. Timco brand fixings, screws and nails are widely recognised as top-shelf. Drawing on 50 years of industry experience they are reliable and cost-effective. Packs contain 50 fixings.
The fixing works by the screw being driven in after being placed through the hole in the plastic cap. Then the cap is shut afterwards, leading to a smooth dome that fends off water. The caps are available in either opaque black or clear.
