What is a 4mm screw? Metric Screw Sizes Explained As a handy coincidence, the Gauge (imperial) roughly equals the screw head size in millimetres. A 4 gauge screw will have a head that is approximately 4mm wide. The gauge (imperial) is half the imperial diameter (in 16th of an inch) of the screw head, roughly. Click to see full answer.

The first number is screw gauge, which refers to the outside thread diameter. This is also known as “major diameter.” Screws with a major diameter less than 1/4” are typically labeled in sizes #0 to #14. Screws with a 1/4" or larger major diameter are labeled in fractions of an inch.
How do I measure screw size?

What is an M8 screw?
What size is m8 screw? 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.
How thick is an M8 screw?
M8 is 8mm thick, and so on. The diameter is measured between the outermost, projecting parts of the screw - the 'tops' of the thread. For most purposes, that's all you need to know. On a standard M5 screw, for example, the grooves are 0.8 mm apart.
What is the M4 thread size?
M4, for example, means the "standard" M4 thread size: for a bolt, the outside of the thread would be 4mm in diameter, and the spacing between threads (the pitch) would be 0.70mm. 34 Related Question Answers Found.
How many threads are in a screw?
Screws have three basic measurements: gauge, threads per inch, and shaft length in inches. So, you may also see a measurement like 6-32 x 1 1/2". 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.
How wide is an M4 bolt?
So, an M4 would be 4mm across at the threaded bit, yes? It's a bit more accurate than that, everything from the diameter of the bolt without the thread, with the thread, pitch of the thread and even the shape of the thread is defined to a tolerance.
