Taper Thread Coupler

As one of the most traditional representatives of mechanical joints, taper thread coupler working principle is to process conical threads at the end of the reinforcing bar and tighten and fix it through a coupler with internal conical threads.

In recent years, on the basis of the common type of conical thread joint, a classic among rebar coupler types, by adding the pre-pressing or rough forging process at the end of the reinforcing bar, the GK type reinforcing bar equal strength conical thread joint has been developed, which can be as strong as the base material.

Taper Thread Coupler Features

Taper thread coupler is fast connection speed and good alignment; Safe and reliable, easy to operate, and capable of withstanding both tensile and compressive forces.

Advantages of tapered threaded splices:

The thread profile of tapered thread rebar connectors is tapered, with the major diameter gradually changing along the axial direction, exhibiting a tightening characteristic as it is tightened.

Therefore, the unique tapered thread structure makes it easy to insert and center the rebar end, requiring only a small amount of rotation to complete the tightening.

Disadvantages of tapered threaded splices:

Due to the tapered design, the stress-bearing area of the thread is relatively small, and the minor diameter of the tapered thread weakens the cross-sectional area of the base material during machining, resulting in a lower load-bearing capacity.
