Wrenches are the basic tools used in most of the industries on a regular basis. For efficient bolting, wrenches are important tool as better bolting is necessary for better quality and better safety assurance in industries hence wrenches are significant tools for any industry. There are many different types of wrenches used in industries that can be used for different type of bolts, nuts, studs and fastener. Here are some of the most used wrenches in industries and also in household.
Open end wrenches
The open end wrenches are the wrenches that have holders at both ends. The holders are inclined at a certain angle to the middle crank to facilitate better grip while using the wrench. The both ends have different sizes of holders; hence nuts with two different head size can be fastened or tightened with the help of an open end wrench.
Impact wrench
Impact wrenches are the wrenches mostly used in the areas where you need high power, but not very high degree of accuracy. The impact wrenches utilise a very high impact forces for giving rotation to the fasteners, thus are very noisy. There is no means of determining the amount of force applied on the wrench, therefore they are not very accurate. The impact wrenches are used along with special sockets as normal sockets cannot survive the high impact force applied on them. For this reason, sockets made from high speed steel are used as they cannot deform and shatter under the influence of very high impact forces, which make them ideal for use with impact wrenches. The impact wrenches are available in three different variants that are electric impact wrenches, pneumatic impact wrenches and hydraulic impact wrenches.
Torque wrenches
When you want a very precise and silent bolting operation, you can use torque wrench as they provide a means of measuring and determining the amount of force that you have applied on a fastener during the operation. This helps you in deciding when you should stop the application of force. The torque wrenches are provided with digital or analogue displays that provide you accurate information about the amount of force applied on the fastener. This avoids any damage to the fastener head as you would never over-tighten the fastener.
The torque wrenches can also be per-programmed for a certain value of torque to be applied so that they can automatically stop when the desired amount is reached. The torque wrenches are also available in several variants namely simple torque wrench, pneumatic torque wrench and hydraulic torque wrench. Out of all, the hydraulic torque wrenches are the most accurate ones as they provide you exact reading of the force that you have applied on the studs or fasteners.
Out of these wrenches available in the market, you can choose the best wrench that suits you budget and type of operation for better accuracy and efficiency.
