What does M8 mean on thread size?
The defined diameter of metric bolts is actually slightly larger than the actual diameter of the bolt shaft. So an M8 bolt would have a shaft diameter that’s slightly under 8mm which means that the bolt should fit through an 8mm hole.
What does M8 refer to?
M8 means “Mate.” The abbreviation M8 is an informal term of endearment for a friend. Most often used between men, M8 can also be a term of general acknowledgement. M8 uses the number 8 to replace the letters “ate.” Here are some other terms that make use of this efficiency: D8 (Date)
What is M8 in standard?
M stands for “Metric”. 8 is the bolt diameter, in millimetres. It usually comes with an additional number, such as 1.0, which is the pitch (distance between threads) in mm. This is the main difference with 5/16 bolt.
What do bolt size numbers mean?
The number 1 or number larger than one, or number one or number larger than one followed by a fraction, is the diameter of the shaft. The number following the hyphen is the number of threads per inch; that is, the number of threads on the shaft itself, per inch of shaft length. Same as for smaller parts.
How are M bolts measured?
Do not measure the head of the bolt, measure the threaded part, outside of the threads. If your bolt is metric, then the diameter is stated using the letter “M”. For example, if your bolt has a diameter of 4mm then it is called an ‘M4 bolt’ if your bolt is imperial then it will be measured in inches.
What size is m12x1 25?
25 Thread Size, 42.07 mm Thread Lg, 85.72 mm Overall Lg, Plug. Country of Origin USA.
Is M10x1 25 fine thread?
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.
What does M12x1 25 mean?
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 read a metric bolt?
M10-1.0 x 20 M = This designates the fastener is a metric size. 10 = The nominal diameter in millimeters. 1.0 = The thread pitch, or distance between threads, in millimeters. 20 = The fastener’s length, in millimeters.
