Use of torque wrench 
Hex nuts or bolts are especially convenient for dismounting hex nuts or bolts at slightly concave places. This is a plum wrench, commonly known as an eye wrench.

A tool that tightens or unscrews bolts or nuts. Three types commonly used by electricians are 200, 250, 300mm. Adjustable spanner is also called flexible spanner. The nuts should be chosen according to the size of the nut.

Right hand shake the handle, the more back hand, when using, the more easy to pull up.

The need to constantly turn the worm gear, when the small nut. Adjust the size of the wrench, so the hand should be held close to the stay lip and adjust the worm wheel with the thumb to fit the size of the nut.

Leave the lip on the top, and hold the nut on the wrench's wrench. Live labrum below. Adjustable spanner must not be used in reverse.

A few drops of kerosene or oil can be put on the nut, when the rusty nut is pulled. It's easy to twist

Do not use steel pipe sleeve on the handle of the adjustable spanner to increase torque, when twisting. Because so very easily damage the active labrum.

Don't use an adjustable spanner as a hammer.

The opening is suitable for the size of bolt head and nut and is made into a set according to the standard size. Rural electricians often use an open spanner (also known as an open spanner), with one end and two ends.

Just turned 30 °, whole have square, hexagon wrench, dodecagon (commonly known as ring spanner) which the ring spanner is widely used in rural electrician. You can change the direction of the trigger, so it's easier to work in narrow places.

The socket wrench is made up of a set of different size plum tubes. Higher efficiency. Ratchet wrenches are used when the screw or nut is large or the wrench is in a narrow working position. The Angle of the wrench swing is small and can be tightened and the screw or nut released. Turn the handle clockwise when tightening. The square sleeve is fitted with a brace. When the handle pulls back in the opposite direction, the brace bar slides out on the ramp of the ratchet teeth, so the screw or nut does not follow the reversal. If you need to loosen the screw or nut, simply flip the ratchet wrench and turn it counterclockwise.

Hexagon socket wrench is used to assemble and disassemble hexagon screws. Usually used for the disassembly and installation of some mechanical and electrical products.

With a handle at one end, the force wrench has a long elastic bar. The other end is fitted with a square or hexagonal head, and a replaceable sleeve is jammed with a steel ball. There is also a long pointer at the top. The dial plate is fixed on the handle, with a scale value of 1 Newton (or kg/m) per square. This wrench is used when a certain amount of twisting force is required, or several nuts (or screws) require the same amount of twisting force.

Outside electricians can use it to load and unload steel structures such as iron towers, and hexagonal wrenches are used to assemble and disassemble large hex screws or nuts.

 
Common types of spanner:

A fixed size opening at one end or both ends for turning a nut or bolt of a certain size.

Spanner: the working end with hexagonal or twelve-angle holes at both ends is suitable for small working space and can not use ordinary spanner.

Dual-use spanner: one end is the same as the single end spanner, the other end is the same as the plum spanner, and both ends turn the bolts or nuts of the same specification.

Adjustable spanner: the opening width can be adjusted within a certain size range, which can turn bolts or nuts of different specifications.

Hook spanner: also known as crescent wrench, used for turning flat nuts with limited thickness.

Socket wrench: it is made up of a plurality of sleeves with hexagonal or twelve-angle holes and equipped with handle, joint bar and other accessories. It is especially suitable for bolts or nuts with very small or deep dents.

Hexagon spanner: an L - shaped hexagon rod wrench used for turning hexagon screws. The model of the hexagon wrench is in accordance with the hexagonal side size, and the size of bolts has national standards.

Torque wrench: it shows the torque applied when turning the bolt or nut. Or when the applied torque reaches the specified value, a light or sound signal is emitted. Torque wrench is suitable for assembly work where torque size is clearly specified.
