How do I calculate how many fasteners I need?
The hidden fasteners can be calculated at 90 fasteners per 4.5sqm of decking, this would allow for the recommended spacing of centres on composite decking installations

Do they come in different colours?
There is only one finish for the hidden fasteners which is the plain black plastic. The spacers are barely visible between the boards and so colour shouldn’t be an issue.

Can they be fastened to a metal sub-frame?
They can be used on a metal sub-frame however they will need a pilot hole prior to fastening.

Are the screws available in different lengths?
The hidden fasteners come with one size screw as standard and can’t be changed. It is possible to replace them yourself, but they must work with the spacers.

How quickly can they be delivered?
All fittings & accessories can be couriered on 2 working day basis.

How far do the spacers separate the board?
The spacers separate the boards by a distance of 6mm, which is the recommended gap in the installation guide.
