#### What does M2 0.4 mean?

The standard pitch (distance between the threads) on an M2 is 0.4mm however we can offer non-standard pitches to order. Each screw size is described using two numbers – the ‘M’ number and a number indicating the length of the shank, in mm, so M2 screw dimensions of M2 x8, are 8mm long, measured under the screw head.

**How do I know what size screw I need?**

The general rule of thumb is that the screw should enter at least half the thickness of the bottom material, e.g. 3/4″ into a 2 x 4. The other factor is the screw’s diameter, or gauge. Screws come in gauges 2 through 16. Most of the time you’ll want to go with a #8 screw.

**What diameter is a number 6 screw?**

This means it’s a #6 diameter, with 32 threads per inch (almost double the normal thread count as a standard wood screw) and an inch and a half long. When the middle number is absent (6 x 1 1/2″), the screw has the “normal” number of threads per inch for that size and type of screw (for #6 wood screws that’s 18).

**How to size a metric screw?**

Screws use pitch as a measurement in the metric system instead of thread spacing. Use a measuring tape or ruler to measure the distance from one thread to the next in mms to get this final measurement. Most screws in the metric system have 1 pitch that corresponds to each diameter. For instance, 2 mm screws have a pitch of 0.4 mm.

M8 is the designation for a metric (M) sized bolt or screw that is 8mm (8) in diameter. This is roughly equivalent to a 5/16 bolt or screw.
