AN hardware is 1/16" per digit, so AN4 is 1/4", AN6 is 3/8", AN8 is 1/2" and AN12 is 3/4" or 12/16"
he diameter of the bolt.
by using a caliperhttp://www.technologystudent.com/equip1/vernier3.htm
A diameter is a property of circular objects. "12 inches" is not a circular object and so cannot have a diameter.
Circumference = 37.7 inches Diameter = 12 inches
if the diameter 5/16 inches then you covert the 5/16 into 0.3125 inches. divide 5 by 16=0.3125 which is a little bigger than 0.3! ;)
The first technician is correct, it is a coarse thread. I'm not sure there is a bolt called 12-13 so I am assuming you meant 1/2 - 13. Wich would be a bolt 1/2 inches long. The diameter of a #13 unc bolt would be ( 13 x .013in ) + .06 = .229 inches in diameter.
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.
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.
