How do you calculate thread pitch?
Another way to measure thread pitch is to place a steel rule down into the axis of a screw and then count the number of thread crests in a given length from that point. The pitch can be calculated by dividing this count by the length.
What is the most common M12 thread pitch?
If you need to know the threads per inch of a metric fastener, first convert pitch from millimeters to inches (multiply by 0.03937), then divide 1 by that number. Or, use the table below…
…

Metric | Closest Inch |
---|---|
M8-1.25 | 5/16-18 (Smaller) |
M10-1.5 | 3/8-16 (Smaller) |
M12- 1.75 |
1/2-13 (Larger) |
M14-2.0 | 9/16-12 (Larger) |

What is M6 thread pitch?
M6 threads are 6mm metric screws. The standard metric rack screw is called M6 x 1. The ‘M’ means it’s metric. The ‘6’ is the outside diameter measured in millimeters, and the ‘1’ is the distance between adjacent threads, also in millimeters.
What is coarse pitch?
Making a large angle between the blade chord and the plane of the propeller disc, thus producing a high forward speed for a given rotational speed.
What is pitch formula?
PITCH-This is the distance from a point on the screw thread to a corresponding point on the next thread measured parallel to the axis of the thread. It is represented by the letter p. (p=1/n).
What is thread pitch?
The thread pitch is the distance between corresponding points on adjacent threads. Measurements must be taken parallel to the thread axis.
What is a thread pitch gauge used for?
Thread pitch gauges are used as a reference tool in determining the pitch of a thread that is on a screw or in a tapped hole. This tool is not used as a precision measuring instrument, rather it allows the user to determine the profile of the given thread and quickly categorize the thread by shape and pitch.
What is the standard M16 thread pitch?
Tapping Drill and Clearance Hole Drill Sizes
With metric threads tapping drill size is easy to work out because it is the bolt diameter minus the thread pitch so, for example, a standard pitch M16 bolt has a pitch of 2.0mm so the tapping drill size is 16 – 2 = 14mm.
What is M12 x1?
M12x1. 75 is the measurement code that indicates the thread size and thread pitch of a screw. The first half (M12), is the size measurement (metric) taken across the outside diameter of the thread (which in this case is 12mm).
What is M12 thread size?
Tap size | Basic major dia (mm) | Basic major dia (inch) |
---|---|---|
M10 x 1.25 | 10mm | .3937 |
M12 x 1.75 |
12mm |
.4724 |
M12 x 1.25 | 12mm | .4724 |
M14 x 2 | 14mm | .5512 |
What is 1.5 thread pitch?
The thread pitch is the distance between threads expressed in millimetres (measured along the length of the fastener). For example a thread pitch of 1.5 means that the distance between one thread and the next is 1.5mm. In general smaller fasteners have finer thread so they have lower thread pitch.
What is M18 thread size?
Thread Geometry – Metric Coarse
Thread | Major Diameter | Pitch Diameter |
---|---|---|
M12 | 12.0 | 10.863 |
M14 | 14.0 | 12.701 |
M16 | 16.0 | 14.701 |
M18 |

Is 5/16 The same as M8?
Well, quick answer is no. They are not the same and they are not interchangeable, although they can work under certain circumstances. The most important part is understanding the meaning of M8 and 5/16 to refer to the size of a metric screw or bolt, so then we can see why they aren’t the same thing!
What does 4g6g mean?
For instance, a thread designated as M5 x 0.8 4g6g would define a thread of 5 mm diameter, 0.8 mm pitch, with a pitch diameter tolerance grade 6 and allowance “g”.
What is M12 in engineering?
The two threads most commonly found in plant and machinery are commonly known as ‘standard’ and ‘fine’ pitch. The pitch of a thread is the distance between two adjacent threads and is measured in millimetres.
…
Size | Pitch (std) | Pitch (fine) |
---|---|---|
M8 | 1.25 | 1.0 |
M10 | 1.5 | 1.0 or 1.25 |
M12 | 1.75 | 1.5 |
M16 | 2.0 | 1.5 |
What does M8 1.25 mean?
ago. M means metric. 8 means 8mm nominal diameter (the thread will be less than 8 mm at the widest point) X 1.25 means 1.25 mm per thread (thanks the standard coarse pitch for this thread)
What is M20 thread size?

M22 | 22.0 | 20.376 |
M24 | 24.0 | 22.051 |
What does M12 mean?
6. Those are metric screw dimensions. M10 means a 10 millimeter outer diameter for the bolt or whatever piece it is; M12 means 12 millimeters. The part after the ‘x’ is the pitch — how many mm a thread is wide. To figure out which you have, you can measure the existing part with calipers and a thread gauge.
Are M6 and 1/4 20 the same?
An M6 will thread a few turns into a 12-24 nut, but additional turns ruin the threads. Same with a 1/4″-20 and an M6. A metric/SAE screw gauge costs $4. That’s a one-beer tool.
