A carriage bolt is a type of threaded fastener designed
to be used with wood, although specialized versions can be used to fasten metal
components. Also known as plow bolts or coach
bolts, carriage
bolts can be found in many hardware stores in an assortment of lengths,
diameters, and thread pitches. They are usually made from various types of
steel for strength and durability, though other materials can be used to make
them as well.
Design
The design of a carriage
bolt includes a large round, domed head with an externally threaded bolt
projecting from it. The head is typically at least twice the diameter of the
bolt shaft, and usually does not have slots for a screwdriver or other driving
device. Underneath the head, there is a square fitting that grips the wood as
the bolt is placed and fastened, keeping it from twisting or turning and
otherwise maintaining a snug fit. In a variation on the basic carriage bolt,
the square fitting under the rounded head is replaced with ribbing that holds
the bolt in place when it is used with other metal components. The length of
the bolt itself will vary according to its intended use, as will the diameter
of the bolt and bolt head, regardless of the type of materials being fastened.

Notes: |
Carriage bolts are pushed into a hole the
same size as the shank and then hammered in the rest of the way, where the
square shoulder locks it firmly in place. Used whenever a smooth finish
surface is needed so that nothing becomes snagged on the fastener. Zinc
plating, retards the corrosion rate in a normal atmosphere. |
