What is meant by 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 size is a M16 bolt?

Metric Hex Bolt Dimensions

m14 14.00 20.67
m16 16.00 23.67
m20 20.00 29.16
m24 24.00 35.00

What is a M16 thread?

In the example above, a pitch of 1.0 means that from one thread to the next thread, the distance is 1.0 millimeter.

Table 3.

Metric Closest Inch
M10-1.5 3/8-16 (Smaller)
M12-1.75 1/2-13 (Larger)
M14-2.0 9/16-12 (Larger)
M16-2.0 5/8-11 (Smaller)

How are M16 bolts measured?

Measure the length from underneath the head to the end of the bolt. This includes the shank, if your bolt has one. A shank is an unthreaded part underneath the head. If you are measuring a countersunk screw make sure to measure the entire length.

What does M mean on a bolt head?

Fortunately, metric bolts are marked differently than SAE bolts. An ISO metric bolt larger than 6 mm in diameter has either “ISO M” or “M” embossed on top of the head. … The number has nothing to do with the size, but does indicate the relative strength of the bolt. The higher the number, the stronger the bolt.

Is an M12 bolt 12mm?

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 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.

Is M16 a 16mm?

M16 (16mm) Hex Nut – Steel (Pack of 10)

What does M12 mean on a bolt?

M12x1. 75 is the measurement code that indicates the thread size and thread pitch of a screw. The first half (M12), is the size measurement (metric) taken across the outside diameter of the thread (which in this case is 12mm).

What does M10 bolt mean?

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.

What is an M8 bolt?

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. … For example, an M8 bolt with a standard coarse thread pitch of 1.25mm would require a hole of 6.75mm diameter to be tapped.

What do bolt numbers mean?

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 is the strongest grade bolt?

Grade 9 structural bolts, also known as grade 9 hex cap screws, are one the strongest structural bolts that can be used today. While the typical grade 8 bolt has a tensile strength of 150,000 PSI, a grade 9 bolt has a tensile strength of 180,000PSI.

What does 8.8 on a bolt mean?

A property class (PC) is the metric equivalent of a grade in inch series terminology. … So, in English, a PC 8.8 bolt is a bolt with a nominal tensile strength of 800 MPa and a nominal yield strength that is 80% of the bolt’s nominal tensile strength, or 640 MPa.

Whats stronger Grade 8 or Grade 5 bolt?

Grade 8 bolts have been hardened more than grade 5 bolts. Thus they are stronger and are used in demanding applications such as automotive suspensions. Grade 8 bolts have 6 evenly spaced radial lines on the head. Grade G is roughly equivalent to Grade 8.
