What is hydraulic bolt?

A hydraulic bolt is a type of bolt that utilizes hydraulic pressure to achieve its tightening or loosening. It typically consists of a threaded bolt with a hollow interior through which a hydraulic fluid can be pumped. When pressure is applied to the fluid, it exerts force on the bolt, either tightening it by compressing the components being fastened together or loosening it by relieving the tension.

Hydraulic bolts are commonly used in applications where precise and uniform bolt loading is required, such as in heavy machinery, construction equipment, and structural engineering projects. They offer advantages such as accurate torque control, uniform bolt loading, and the ability to work in tight spaces where traditional tools may not be feasible.
