What are stairs?
They are a means to pass from one level to another. There is a lot of jargon used around stairs, that can complicate things when you are looking to design, renovate or buy a staircase. Do you know what a riser is, or a tread, a balustrade, a closed stairway, a stairwell, pitch, or nosing? A riser is the vertical distance from one tread to the next, and the vertically faced board connecting the treads.

Do you Know the Different Parts of a Screw?
There are three parts of a screw, they are the head, shank and thread.
- The Head – has the slots for the turning tool to fit into.
The Shank – is the smooth part above the thread and below the head.
The Thread – is the tapering groove that spirals towards the tip. This cuts into the wood as it is turned then pulls the screw into the hole.
