The length of a metric bolt is measured and defined in exactly the same way as imperial, inch-based bolts and fasteners. Socket head, pan head, button head and hex head bolts are measured from the underside of the bolt head to the end of the shaft.

What does M8 1.25 mean?
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)Nov 9, 2020.
What size is M18 bolt?

How can you tell if a bolt is metric or standard?
Telling the difference between a metric and imperial bolt is easy. If the bolt has lines on the head its standard or imperial. If the bolt has numbers on the head then its metric.
What does M12 mean?
The first half (M12), is the size measurement (metric) taken across the outside diameter of the thread (which in this case is 12mm). The second half is the thread pitch, which is the measurement of threads/inch (which in this case is 1.75).
What is a 10mm bolt in standard?
So what is a 10mm socket equivalent? The equivalent imperial size of a 10mm socket is a 3/8 socket. Imperial sizes are known as SAE (Society of Automotive Engineers) or Standard.
What does M10x1 25 mean?
Understanding Inch & Metric Thread Callouts For example, an M10x1. 5 (coarse) thread has a 1.5mm pitch, while an M10x1. 25 (fine) thread has a 1.25mm pitch. For example, the thread “M10” automatically means a coarse pitch, while any added pitch callout, such as M10x1. 25, specifies a non-coarse pitch.
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!.
How many mm is M8?

Is M18 an 18mm?
M18-1.5 or 18mm Metric FINE Thread Hex Nuts Steel Din 934 Yellow Zinc – (5 Pcs).
How do you tell the difference between metric and standard sockets?
SAE sockets are sized in inches and fractions of inches. Metric and SAE wrenches have different systems of measurement. Metric sockets and wrenches use the metric measurement system. This is when millimeters are used to describe the size.
Do you need both SAE and metric?
For general automotive work – you will need both. With American cars they are mixed – sometimes on the same part… (Ie the housing bolts are 9/16 but the nut on the pulley is 19 mm…) Older heavy equipment is all SAE, newer stuff mixed foreign stuff metric.
Is M10 a 10mm?
If the size is M10 x 25, that would mean that the diameter is 10 mm. The 25 indicated a length of 25 mm. A matching nut would be labeled M10, which also doesn’t require a thread pitch since it’s a course thread fastener.
What size is M12X1 75?
TAP DRILLING SIZES DRILLED HOLE SIZE Metric Coarse Screw Threads UNF Screw Threads M9X1.25 7.8 14.5 M10X1.5 8.5 17.5 M11X1.5 9.5 20.5 M12X1.75 10.3 23.2.
What M12X1 75?
M12x1. 75 is the metric way to indicate a thread. M12 means that the OD thread is 12mm, the 1.75 is the step of the thread.
Whats bigger 3/8 or 10mm?
10mm = just over 3/8 inch. 11mm = almost 7/16 inch. 12mm = almost 15/32 inch (= almost 1/2 inch) 18mm = just over 11/16 inch.
What is 11mm in standard?

What is M3 screw size?
ISO Metric Machine Screw Thread Dimensions Thread Size Nominal Diameter (mm) Thread Pitch (mm) M3 3.0 0.50 M3.5 3.5 0.60 M4 4.0 0.70 M4.5 4.5 0.75.
Does M12 mean 12mm?
Yes. M12 is a 12mm diameter thread. You have to be sure the thread pitch measured in threads per millimeter (1.5 here) is the same as what u need.
What does M12 mean on bolts?
M12 bolts are a metric sized bolt with a 12mm thread diameter. They have many applications but are often used to fasten metal to wood or to join different types of timber together. They are regarded as a heavy duty bolt and ideal for structural joints.
What does M12 nut mean?
This example illustrates how a coarse threaded screw may appear… M12 x 25 = 12 mm diameter, coarse thread is assumed (1.75 mm), 25 mm long. M12 is a matching coarse threaded nut. (To avoid confusion, we always include the thread pitch for both coarse and fine metric fasteners.).
How do you know if a nut is metric?
If the nut is metric, count the number of lines on the tape measure to find the measurement. If you count 9 lines, the size is a 9-mm (millimeter) nut. If the nut is US standard, count the smallest lines on the tape measure in sixteenths. Add the sixteenths together to find the size.
What is standard metric thread?
ISO metric threads consist of a symmetric V-shaped thread. In the plane of the thread axis, the flanks of the V have an angle of 60° to each other. The thread depth is 0.54125 × pitch.
