For square posts the hole must be slightly larger than the diagonal measurement of the post.
Male pin header dimensions.
For 025 square posts i usually specified 040 finished hole size size after plating.

Other sizes are also available like 1 27mm 05in or 2 00mm 079in.
In the past a pin header was known as a berg connector but the term fell out of favor because pin headers are manufactured by many companies.
Headers are normally through hole devices but you can also find surface mount technology smt headers.
A in that picture is the side that goes through your pcb.
The pins in the common 0 1 post headers are 025 square.
Pitch between pins size of the pin length of the bottom side length of the post and length of the top side.

A through hole header has five main dimensions.
It consists of one or more rows of male pins typically spaced 2 54 millimetres apart but common sizes also include 5 08 millimetres 5 00 millimetres 3 96 millimetres 2 00 millimetres 1 27 millimetres and 1 00 millimetre.
Jst manufactures numerous series families and pitches pin to pin distance of connectors.
If the corners were not rounded they would be 905mm on the diagonal and would require at least a 36 mil hole in a pcb.
