In the next few sections, we’ll list each screw by diameter/gauge, and the available sizes for each of those screws. 3mm/Gauge Size 4

For something like a screw, the measurements match up quite nicely when you convert them. However, if you’re trying to figure out liquid measurements, you should know that the US uses different measurements for their pints and gallons. While the metric system uses millimetres to measure screw sizes, the imperial system uses inches. In the UK, we use the metric system (which is prevalent in all of Europe), while the imperial system is used in the US.Despite being a metric area, there are many places in the UK that still use imperial measurements. As such, it’s a good idea to be familiar with both measurements for screws. Longer screws will, obviously, go further into your walls than shorter screws.

Grown from the Eucalyptus Grandis tree in South Africa, these poles have a natural taper over their length. They are very strong, with a density similar to oak, and their natural appearance make them perfect for a variety of uses. Take the mystery out of your next DIY endeavour with our handy guide on the UK’s numerous screw sizes. UK screw sizes Natural Hardwood Poles are stripped of bark, Tanalith E treated, and are far stronger than bamboo or machine round alternatives. They are strong enough to be used in building construction.
