The table of flat washer dimensions was adapted from Table 11 for type A plain washers.The type A washers are narrow and wide.
The standard sizes for coarse and fine pitch thread were used to create the table of thread sizes.Coarse pitch threads should be used whenever possible.The thread equations were used to build the table.
"M[dia] x [pitch]" is the thread size designation for metric thread.A thread with a nominal diameter of 6mm and a pitch of 1mm is called "M6 x 1."
The dimensions for ISO metric threads can be calculated using the following equations.The thread profile is based on the height of the fundamental triangle.The thread pitch is related to the value of H.
The thread pitch and nominal diameter are shown in the table.
