Description
Delivery

Big twist nails, or helical twist nails, are an innovative product designed specifically for fixing composite boards, such as Kingspan or Celotex 6mm plywood composite warm roof insulation boards to timber substrates. The big twist nail is made from 8.8 high tensile steel, making it strong and reliable. The helical shank means the nail rotates during installation, helping reduce the risk of the timber splitting. There is no need for pre-drilling or screws, meaning the Bigtwist nail saves you time & money compared to more traditional fixings.

Features

No drilling - means quick installation
No need for traditional screws
Unlike a normal nail, the big twist nails rotates whilst being driven in, reducing the risk of the timber splitting
Unique one-piece stress free fixing Improved design to prevent bending during installation
Large 20mm Ø head means they are easy to hammer in
Approved by the major insulation suppliers

Fixings & Fastenings are most commonly priced in quantities of 100 or 1000. We commonly display our pricings in this format as it gives you the most accurate cost per unit, however this does not mean that we only sell in these quantities - you can still buy invidually.

Take this product HELITC8X220 for example - the displayed price of £0.53 is per 1 units, so the individual unit price is £0.5280 each. The price varies depending on the quantity that you are looking to buy. Please see the table below for some examples.
