What size would I need if my sleepers are 200x100 and 2.4ft long please?

Hi If you are wanting to screw them together you would ideally need 150mm screw Hope this helps you Paul

How do I work out how long the screws are

In this case the screw has a length of 60 mm from screw tip to shoulder. "Hex Head Timber Screw 6.7 x 60" is a timber screw with an hexagonal head of 6.7 mm and a length of 60 mm.

How long will delivery be?

We will dispatch on Monday on a next day delivery but it is not guaranteed carriers are struggling a bit at the moment but it is dhl/Uk mail

How does this work as I need to join two sleepers together so they're sat tight? Do you need pilot hole and if so what screw size?

You don't need a pilot hole but you want 6.7 x250 self screwing screws if you are joining the sleepers one on top of the other edge wise.
