Cup square carriage bolts meeting standard DIN 603 with hex
nuts meeting standard DIN934 are mostly used in wood. The Cup Square Bolts also
known as a coach bolt or carriage bolt have a domed top and a square under the
head which pulls into the part being fixed, preventing the bolt from turning
when the nut is tightened.
A carriage bolt is also commonly used in drilled concrete
fences and gate posts to fasten wooden posts and panels

Cup square bolts are also commonly referred to as carriage
bolts or coach bolts due to their original usage in the manufacture of rolling
stock. Cup square bolts consist of a domed circular head with a square neck
portion and then a round shank.
The shank consists of both a plain load bearing portion as
well as a threaded portion. Cup Square bolts are usually used in conjunction
with a hexagon threaded nut (cup square hex) which fastens onto the thread of
the Cup square bolt.
The bolt is locked into placed by the square neck as the nut
is fastened onto the stationary bolt. Cup square bolts are widely used in
construction, engineering, fencing and woodworking environments.
As with hexagon headed bolts, when measuring the length of a
Cup square bolt it is important to measure from the underside of the head and
not to include the bolt head to the end of threaded portion.
The diameter of the cup square bolt is measured from the
actual diameter of the threaded portion and not the square neck.
Typically the square under the head is the same as diameter
for example on a M8 carriage bolt the square will be 8 x 8 mm
