How to read bolt sizes

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 does M10 mean in bolt size?

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 M14 x2 mean?

Inch. Fine. 0.025. 40. The threads of an M14-2.0 screw, which is coarse, are spaced 0.079 inches (2.0 mm).

What does M14x1 mean?

For example, if the metric bolt was M14x1. 5x25, it would have a diameter of 14 millimeters. Determine the distance between threads by looking at the second number. For example, if the metric bolt was M14x1. 5x25, it would have 1.5 millimeters between threads.

Does M12 mean 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.

What size is M10?

Size	Clearance Hole mm	Tapping Drill (fine pitch)
M10	11	9.0 or 8.75 mm
M12	14	10.5 mm
M16	18	16.5 mm
M20	22	20.5 mm

Is M12 bigger than M10?

M10 male fasteners are usually 1.5 mm or 1.25 mm distance from crest to crest. M12 male fasteners are usually 1.75 mm or 1.5 mm crest to crest.

Is M10 a 10mm?

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).

What does M6 bolt mean?

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″).

What does M4 bolt stand for?

The M4 machine screw has a thread diameter of 4 millimetres, in simple terms the M stands for millimetres followed by the size – in this case 4 mm.

What does 10.9 mean on a bolt?

Class 10.9 Alloy steel, quenched and tempered.

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 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 m8x1 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.

Are 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..

What does M14 bolt mean?

M14 means it is metric with a 14mm outside diameter.

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.

What does M8 mean?

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

What does M8 bolt mean?

The standard system sizes are expressed in inches. For example, if you see a bolt size expressed as follows: M8x1.25x16. M8 refers to the 8mm diameter of the threaded portion. 1.25 refers to the 1.25mm pitch of the threads (1.25 is the most common)

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.
