Understanding The Different Options Of Hydraulic Torque Wrenches

In case, an ordinary socket wrench does not fulfill the specific requirements of the individual, then he can easily step up to having a good and top quality hydraulic torque wrench or electric torque wrench that is manufactured by any reputed hydraulic torque wrench manufacturer. There are numerous manufacturers, who are known to provide variety of torque wrenches to their clients. However, before trying to purchase one, it is very much essential for the person to understand each type of power tool and what it is meant for, so that the selection becomes a well informed one.

Understanding The Different Options Of Hydraulic Torque Wrenches

What is Hydraulic Torque?

Starting with the basics, a hydraulic torque has been designed for exerting torque on some type of fastener. The objective could be to securely and quickly loosen or fasten various nuts. They tend to apply a torque amount to lubricated fastener that is much beyond what a person could muster, generally in conjunction with impact socket. These were said to be introduced first in 1960’s. However, it has evolved with time since manufacturers have been trying to advance and update their designs constantly. It has led to the introduction of sophisticated type of hydraulic torque wrench, which is stated to be light because of exotic alloys, thereby having small nose radius for increasing number of space which would fit into it, possessing multiplication reaction members. This way the person can now easily run multiple tools on a single power pack simultaneously. The modern torque wrenches these days have been optimized for greater flexibility and efficiency in their uses.


What is said to make the hydraulic torque wrench to work perfectly is that it has the capability to generate torque by using hydraulic, which means it is regarded to be self ratcheting. Also, it needs to have a precise way for measuring the torque amount that is applied to fastener. The holding pawl design has been quite popular among majority of the manufacturers for locking wrench in its position. However, each of them has some kind of claim stating their design is much more superior to the other. Such wrenches typically tend to have accuracy rating of around +/-3% along with higher repeatability rate. It makes them quite suitable for larger bolts, requiring higher degree of accuracy. A big advantage of using hydraulic wrench is that it does not have anything related with performance, however, with those that make use of them. The torque wrenches are much quicker than similar pneumatic output impact wrenches. It is a benefit which the person cannot measure in repeatability, strength or work output growth. It is more about health of those people who utilize it.

The electric torque wrench, on the other hand, is regarded to be a gearbox which is connected to electric motor. The gearbox has been designed in a manner so as to absorb the torque, thereby allowing user to have the wrench operated with minimal effort. They are used typically, when there is just no use for torque strength accuracy which is used on bolt and nut or if a stubborn nut requires to get removed.
