# What is meant by M16 bolt?

Contents

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

NOMINAL SIZE (D) BODY DIAMETER ACROSS THE FLATS
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.
