Bolt Size Chart

The size of a metric bolt is specified using pitch, diameter, and length in millimeters. For example, in M8-1.0*20, the “M” means the Metric thread designation, the digit 8 refers to the Nominal diameter (in millimeters), 1.0 refers to the pitch, and 20 refers to the length.

What size is a M10 bolt?

Steel bolt with M10 metric thread. Metric threads are designated with a capital M plus an indication to their nominal outer diameter and their pitch: This bolt is M10 x 1.5 - which means the outside diameter is 10mm and the threads are 1.5mm apart (the most common thread pitch for M10). Threaded part is 50mm long.

How do I know what size bolt?

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 size is M12 in MM?

Size	Spanner	Allen Key

What does M10 mean on a bolt?

M10-1.0 x 20 Taking a closer look at this description, let's explore its meaning: 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.

What does M8 mean?

m8 (plural m8s or m8's) (Internet slang, text messaging) Abbreviation of mate.

Is M10 bigger than M8?

10mm is larger than 8mm. The second number is the thread pitch. The nut and the bolt need the same pitch.

What does M5 mean?

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 is M5 bolt size?

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.

What does M16 bolt mean?

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.

How do you tell what thread a bolt is?

Use a caliper to measure the nominal male or female thread press to crest diameter on the first

What size is a 3/4 bolt in metric?

Metric	Closest Inch
M14-2.0	9/16-12 (Larger)
M16-2.0	5/8-11 (Smaller)
M18-2.5	3/4-10 (Larger)
M20-2.5	3/4-10 (Smaller)

Is M12 the same as 12mm?

A: 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.

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 size is a M20 bolt?

Is M10 and 3/8 the same?

That said, they are very close, the 3/8" bolt is about 0.019" smaller and the pitch's are very close so the 3/8 -16 bolt will thread in the 10mm x 1.5 but the 10 x 1.5 bolt will not fit the 3/8 but..

Is an M10 bolt 10mm wide?

What size nut (M12, M14) fits a bolt which is 10mm in diameter? If the bolt is 10mm in diameter (nominal), and metric, it will have a M10 thread.

The M5 screw has a diameter of 5mm.

What does 8.8 mean on a bolt?

So, in English, a Property Class 8.8 bolt is a bolt with a nominal tensile strength of 800 MPa and a nominal yield strength that is 80% of that nominal tensile strength, so 640 MPa.

What does M6 mean on a 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 1 mm. The number 1 mm refers to 1 threads per millimeter. You can identify an M6 screw by measuring the diameter at slightly more than 7/32″ (0.2362″).
