hydraulic bolt wrench

A hydraulic torque wrench is a device with calibration that can measure the torque applied to fasten and attain the desired tightness or loosen a bolt. It was invented by George A Sturdevant in 1968. Since then, they are used in a cross-section of industries prominent among which are transportation, field erections and oil and gas explorations.

How to choose a hydraulic wrench? 1. According to bolt specifications: there are generally several specifications, such as M36, M42, M48. If you don't say what's the size of the nut, it is the opposite side of the matching socket of the metric bolt and nut pair. The hexagon opposite side of the nut is 55 for M36, 65 for M42, and 75 for M48.

Hydraulic bolt tensioning tools tighten large diameter bolts quickly and easily to high and accurate pre-loads. Unlike conventional methods, it does not use torque. The forceful turning of the nut or bolt, like impact wrenches, flogging spanners or hydraulic torque wrenches is not required. All of these methods have one common enemy, FRICTION.
