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.
What does m8x1 25 mean?
For metric fasteners, you will see a M8 x 1.25 or an M8 x 1. For thread pitch, the distance between two points is the second number meaning
the higher the number the fewer threads there are
. This means the M8 x 1.25 is the coarse threading and the M8 x 1 is the fine thread.
What does M8 bolt mean?
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. But it’s common practice to drill clearance holes that are slightly larger to allow for misalignment.
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 does M8 mean?
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.
What does 8.8 on a bolt mean?
The grade 8.8 refers to the
tensile strength which is generally 116,000 psi
, grade 10.9 is generally 150,000 and grade 12.9 is generally 175,000 psi.
Is M10 the same as 10mm?
If the size is M10 x 25, that would mean that the diameter is 10 mm
. Since there is no thread pitch listed, the fastener is assumed to have a coarse thread. 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 M10 nut?
M10 (
10mm
) Thread Size.

What does M14 bolt mean?
M14 means it is
metric with a 14mm outside diameter
.
What is M6 bolt?
M6 refers to
a metric 6 mm screw
. The outside diameter of the threads is 6 mm. The standard metric rack screw is actually an M6 x 0.1 mm. The number 0.1 mm refers to 0.1 threads per millimeter. You can identify an M6 screw by measuring the diameter at slightly more than 7/32′′ (0.228′′).
Is an M12 bolt 12mm?
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 M9 stand for?
M9 means
best mate

Is Grade 8 the strongest bolt?
A grade 8 bolt is the highest grade SAE bolt
. Grade 8 bolts have a minimum tensile strength of 150,000 PSI. As a comparison, the ASTM A325 bolt is roughly equivalent to the SAE grade 5. A grade 8 bolt would be one that meets ASTM A490 standards.

Whats bigger 10mm or 3 8?
10mm = just over 3/8 inch
. 11mm = almost 7/16 inch. 12mm = almost 15/32 inch (= almost 1/2 inch)
How do I know what size nut and bolt to get?
A typical rule of thumb . . .
Use a bolt diameter that is 1.5 – 2.5 times (up to three times) the thickness of the thinner material you are bolting together
. So, for 1/8′′ material, a 1/4′′ diameter is often a good bolt choice. For 1/4′′ thick material, perhaps a 3/8′′ or 1/2′′ bolt.
How do I know what size nut to buy?
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 size is M5 bolt?
M5 bolts are easy to fix and have a wide variety of applications. These
5mm thread
bolts work with matching nuts and are available with a variety of different heads, meaning there will be something for every type of job.
