5.0mm and 6.0mm are also available for more heavy duty applications.

The length of Decking Screw depends on the application but the most common length is 60mm.

Decking Screws are available in lengths from 30mm to 100mm.

How many screws will I need per decking board?

The number of Decking Screws required per decking board depends on several factors, including size and spacing of the deck board and also joist spacing.

A general rule of thumb is to use 2 Decking Screws per board per joist.

For narrower boards (less than 150mm wide) 3 Decking Screws per board per joist might be required and for wider boards (greater than 150mm wide) its 4 per board per joist.

These are general guidelines and as every application is different it’s important to consult with the board manufacturer for their recommendations.

What’s the best way to screw deck boards?

When screwing down decking boards use at least 2 Decking Screws per joist and take care not to over tighten the screws.

Position the screws at least 15mm from the end of the deck board and 20mm from the edge of the board.

This will reduce the risk of splitting the board.

It is important to leave a gap of around about 6.5 mm between boards and at their ends to allow for expansion but this depends on the moisture content of the board and weather conditions at the time of installation.

If the boards are wet you might want to reduce the gap to 3.5 mm

It’s important to always consult with the board supplier as boards can expand or contract.
