Applying a specific torque to a fastener, such as a nut, bolt, or lag screw, requires the use of a torque wrench. It often takes the shape of a socket wrench with an indication scale or an internal mechanism that will signal when an application has achieved a certain torque value.
When the tightness of screws and bolts is a vital component of assembly or adjustment, a torque wrench is used. It enables the operator to adjust the fastener’s torque to the required level for a specific application. This enables all parts to be loaded and tensioned properly. This is all about the hydraulic torque wrench manufacturers in India.
History of Hydraulic Torque Wrench
An illustration of the patented wrench invented by J. H. Sharp John H. Sharp of Chicago applied for the initial torque wrench patent in 1931. Originally known as a torque measuring wrench, this tool is now known as an indicating torque wrench.
An adjustable ratcheting torque wrench was patented by Conrad Bahr and George Pfefferle in 1935. When the desired torque was attained, the tool’s back-ratcheting movement was restricted and there was audible feedback. When doing his job, Bahr, who worked for the New York City Water Department, became upset with the variable tightness of flange bolts. To solve these issues, he claimed to have created the first torque-limiting instrument in 1918.
How does HTL Provide Torque Wrenches?
Therefore, whether you need equipment for tightening or removing a nut and bolt, HTL provides the accessories and bolt torque equipment to fit your needs. Additionally, HTL offers its own line of hydraulic torque wrench that work with ratchet links and torque wrenches made by companies like Hytorc, Wren, and Rapid Torc.

Automated torque wrenches
The process for measuring torque is the same as it is for a click-type torque wrench, but it also uses an electronic torque wrench to measure the torque as a digital reading. Consequently, this is an amalgam of mechanical and electronic measurements. Wireless data transmission is used to transfer and record each measurement. The wrench “beeps” when the user has reached the desired torque level.
The wrench operates in a manner that is generally similar to that of a typical beam torque wrench. There are two beams, but only one is used to apply torque even though they are both attached to the head end. The load-bearing beam is straight and extends from the head to the handle;
when torque is applied, it deflects. For about half of its length, the other beam runs directly above the deflecting beam before bending at an angle away from it. Throughout the operation, the signaling beam keeps its position and shape. The result is that the relative positions of the two beams differ.
