Wrenches are a hand tool which makes its place in the gearbox
of every mechanic or workmen who deals with nuts and bolts. It is a device
which helps in tightening or loosening of bolts by holding it firmly in its own
place. A wrench is designed as such that it fits the bolt head exactly and
restricts it from slipping while spinning.
Every piece of machinery today has some usage of wrenches.
The size of the bolts is differently built to fit the designated machinery.
Wrenches come in different size and shape to exactly meet the requirement of
each standard bolt. Wrenches are built from chromium-vanadium alloy. The
chromium plating helps the wrenches to stay away from rust. These are strongly
built as it is used extensively in household work and also for industrial work.

Wrenches come in different types and are mainly classified into
three parts namely open end, box end and a combination of both.
ü An open-end wrench has u shaped opening on both
ends which are different in size. The gauge of the wrench is denoted by
numbers. This type of wrench consists of different gauge of opening on both
ends which can be used for 2 different sizes of bolts.
ü A box end wrench is a closed end wrench which
usually makes a hexagonal shape at both ends of the wrench. These wrenches are
fastened into a bolt which has an emerging surface and sometimes it is bent as
a lever which gives the handler an edge to hold it and put extra pressure on it
which is not possible in case of flat handled open wrench. You must have seen
it in the toolbox of a mechanic at a garage while they use it to open or tighten
the bolts of a car’s wheel. This type of wrench is best suitable for places
where an open wrench cannot reach.
ü As the name suggests, a combination wrench is a
combination of both open as well as box wrench in either side. These type of
wrench consists of an open-sided concave wrench in one size while the other
side comprises of a hexagonal loop wrench. Both the ends come in the same gauge
as they are used in combination for a single bolt. Unlike box and open end
wrench, they can only be used for one size of bolt only.
There are other types of wrenches as well such as an adjustable
wrench, torque wrench, socket wrench, Allen wrench etc. All these types of
wrenches have individual work and are well crafted to carry on such work.
Therefore, wrenches hold a special place as a hand tool for
mechanical work. While buying a wrench the material must be judged as it will
undergo a lot of pressure and should sustain for a lifetime. There are many wrench suppliersto choose from who caters to every requirement
