It indicates the diameter of smooth-walled hole that a male thread (e.g. on a bolt) will pass through easily to connect to an internally threaded component (e.g. a nut) on the other side. For example, an M6 screw has a nominal outer diameter of 6 millimetres and will therefore be a well-located, co-axial fit in a hole drilled to 6 mm diameter.
For example, a bolt with coarse threads (16 tpi, 0.0625 in [1.59 mm] per turn) on one end and fine threads (24 tpi, 0.0416 in [1.06 mm] per turn) on the other changes the distance between the nuts by about 0.02 inches (0.51 mm) per revolution and is equivalent to a 48 tpi (0.53 mm/thread) thread:
A machine screw or bolt is usually a smaller fastener (less than 1 ⁄ 4 inch (6.35 mm) in diameter) threaded the entire length of its shank that usually has a recessed drive type (slotted, Phillips, etc.), usually intended to screw into a pre-formed thread, either a nut or a threaded (tapped) hole, unlike a wood or self-tapping screw.

A bolt circle with four wheel nuts on an Acura. The mounting pattern of most car rims are described using bolt patterns, and this pattern is one of many factors which determine whether a rim will fit a given car. Here, the bolt circle indicates the number of wheel nuts and associated hub bolts (or alternatively just wheel bolts). [5] [6]
The first nanotube ropes (20 mm long) whose tensile strength was published (in 2000) had a strength of 3.6 GPa, still well below their theoretical limit. [41] The density is different depending on the manufacturing method, and the lowest value is 0.037 or 0.55 (solid). [37]
Symmons is an English language surname. It stems from the male given name Simon. Notable people with the name include: Charles Symmons (1749–1826), Welsh poet and priest; Charles Augustus John Symmons (1804–1887), Writer from Western Australia; Michael Symmons Roberts (born 1963), British poet
The Minimi fires from an open bolt, which reduces the danger of a round cooking off after extended periods of continuous fire, since a cartridge is only momentarily introduced into the chamber prior to ignition, and the movement of the bolt and bolt carrier forces air through the chamber and barrel after each shot, ventilating the barrel and ...
The handle of the knife, made of elephant ivory, is decorated with 227 animals carved in 10 registers on both faces. [53] The figures are tightly packed and entirely cover the handle. They represent real animals, all depicted at approximatively the same size and arranged in processions by species: elephants (some walking on snakes), storks ...
