#1 Simplest way is to buy a bolt gauge from a hardware store or online.
Example:

#2 Next method is to see if you or someone you know ever purchased an assortment of nuts and bolts from a hardware store that has labeled drawers. Take nut from the labeled drawer and match it up.
#3 You can make your own bolt gauge if you own a set of drill bits. Drill holes in sheet metal or wood and label the holes. Push the bolt in the holes till you find a fit. This will not give you the thread pitch though which you usually need for a mating nut.
#4 If you have a set of wrenches that are the size of the bolt threads match them up until you find a fit. You probably do not have wrenches that small though. I assume it is a small bolt.
#5 Use calipers to gauge the diameter and place the gauge reading on an accurate ruler. This will not give you the thread pitch either.
"M8" refers to the diameter of a metric bolt, where "M" stands for metric and "8" represents the diameter in millimeters. This measurement helps in selecting the correct size of nuts or washers to use with the bolt.
A bolt is a type of fastener that typically has a threaded shaft and a head on one end. In terms of measurement, a bolt is often sized by its diameter, length, and thread pitch. The diameter is the width of the bolt shaft, measured in inches or millimeters.
"M8" refers to the metric size of a bolt. In this case, M8 signifies that the bolt has a diameter of 8mm. It is important to use the correct size bolt for specific applications to ensure proper fit and function.
A lightning bolt can vary in size, but on average it is about 1 inch in diameter and can stretch for several miles in length.
The homophone for bolt is "boult."
This would be concidered the largest diameter,dimension of a bolt.
The standard diameter of an M3 bolt is 3 millimeters.
The standard diameter of an M4 bolt is 4 millimeters.
The nominal diameter of a bolt is the approximate size of the bolt shaft. It is determined by measuring the diameter of the threaded portion of the bolt shaft, excluding the threads. This measurement is standardized based on the bolt's size and type.
he diameter of the bolt.
The stress on a bolt under longitudinal force is the total force on the bolt divided by the stress area. The stress area is a little bigger than the minor diameter area, calculated from the average of the minor diameter and pitch diameter. The total force on the bolt is its torque preload plus the (bolt stiffness/(bolt +member stiffness) x (externally applied load )
On a five bolt pattern measure from outer edge of one bolt then across to the middle of another skipping one bolt hole( not quite the diameter). On six or four bolt patterns measure across from bolt center to bolt center as you would the diameter if it were a circle.
"M8" refers to the diameter of a metric bolt, where "M" stands for metric and "8" represents the diameter in millimeters. This measurement helps in selecting the correct size of nuts or washers to use with the bolt.
The standard m5 bolt diameter used in most industrial applications is 5 millimeters.
An M8x50 bolt is 50 millimeters long and has a diameter of 8 millimeters. The "M" designation indicates that it is a metric bolt, with the number following it representing the nominal diameter in millimeters. In this case, the length of the bolt is specifically 50 mm.
The dimensions of an M3 bolt are 3mm in diameter and the length varies depending on the specific type of bolt.
That refers to the size wrench necessary to tighten or loosen the bolt.
