To measure the diameter of screws and bolts, you measure the distance from the outer thread on one side to the outer thread on the other side. This is called the major diameter and will usually be the proper size of the bolt.
What tool is used to measure the diameter of a bolt?
Measuring the Diameter. Use a bolt gauge to find the diameter quickly and easily. A bolt gauge is divided into standard and metric sections.
What is the diameter of a 6mm bolt?
You can identify an M6 screw by measuring the diameter with a ruler. It’ll be 6 mm, or slightly more than 7/32 inches (0.228″).

What can be used to measure diameter?
A diameter tape (D-tape) is a measuring tape used to estimate the diameter of a cylinder object, typically the stem of a tree or pipe. A diameter tape has either metric or imperial measurements reduced by the value of π. This means the tape measures the diameter of the object.
How do you measure diameter?
Determine the diameter from the circumference by dividing the circumference by the value of pi, which is 3.141592. Pi is the ratio between the circumference and the diameter and when it is divided into the circumference the result is the diameter.
What size bolt is 9mm?
Size Chart Bolt size Size Tolerance 9mm 9.18 3/8″ 9.70 M6 10mm 10.24 M7 11mm 11.24.
How is a 10mm bolt measured?
Fastener length is measured from where the material surface is assumed to be, to the end of the fastener. For fasteners where the head usually sits above the surface, the measurement is from directly under the head to the end of the fastener.
What does 8.8 mean on a bolt?
In the case of a 8.8 grade bolt the first figure signifies that the Tensile Strength is at least 800MPa. The second figure signifies that the fastener will begin to yield at 80% of the Ultimate Tensile Strength, i.e. at least 640MPa.
What diameter is M8?
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 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.
What does M14 mean on a bolt?
M14 means it is metric with a 14mm outside diameter.
What size is a M16 bolt?

What does 4.8 mean on a bolt?
For example, a bolt with a performance grade of 4.8 means: The nominal tensile strength of bolt material is 400 MPa. The yield-strength ratio of bolt material is 0.8. The nominal yield strength of bolt material is 400 x 0.8=320 MPa.
What is a diameter of a circle?
What tool is used to measure the diameter of a wire?
A vernier caliper with a least count of 0.
How many centimeters are in a diameter?

How many inches are in a diameter?
CATEGORIES Diameter Nominal DN (mm) Nominal Pipe Size NPS (inches) Outside diameter (OD) inches (mm) 10 3/8 0.675 in (17.15 mm) 15 1/2 0.840 in (21.34 mm) 20 3/4 1.050 in (26.67 mm) 25 1 1.315 in (33.40 mm).
How do I measure a circle?
The circumference of a circle can be calculated using either of the following formulas: C=????d or C=2????r. We know that the diameter of the circle is 8 cm, and an approximation for pi is 3.14, so we can plug these values into the formula C=????d. The formula becomes C=(3.14)(8), which simplifies to 25.12.
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 is a M16 bolt?
Metric bolts are made fractionally under their stated size, for instance an M16 bolt will have a shank diameter of typically 15.97mm. This means that a 16mm bolt will fit through a 16mm hole but to allow for misalignment between parts it is common practice to drill bolt holes slightly larger.
What diameter is M16 thread?
Tap size Basic major dia (mm) Basic major dia (inch) M14 x 1.5 14mm .5512 M16 x 2 16mm .6299 M16 x 1.5 16mm .6299 M18 x 2.5 18mm .7087.

What is M5 bolt?
Bolts and nuts described as M5 means they are bolts or nuts with threaded 5 mm bodies. Additional numbers in the description indicate thread pitch and length. The M series metric fasteners have standardized pitches and diameters and head wrench sizes.
What size is a 9.8 bolt?
Metric steel bolts, screws and studs – proof and tensile strength. Property Class Size Range (mm) Minimum Tensile Strength (10 6 Pa) 4.8 M1.6 – M16 420 5.8 M5 – M24 520 8.8 M1.6 – M36 830 9.8 M1.6 – M16 900.
What does 3 lines on a bolt mean?
The markings can identify the standard to which the bolt was made. For instance, if a bolt head contains three radial lines, then it’s a Grade 5 bolt. If it contains five radial lines, then the bolt is Grade 8.
Is M8 same as 8mm?
M8 is not exactly 8mm but it is sufficient from a non-engineering point of view as long as the thread pitch is correct. Luckily, most commonly available metric bolts have the same pitch. Regarding tolerance for common uses it can also often be ignored.
What does M3 0.5 mean?
Full Member. 0.5 is the pitch, which is standard pitch for m3.
Are M8 and 5/16 the same?
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!.
