Accurate control of the bolt-tension with un-loosening function
When doing torque-fastening, the tension in the bolt is very incorrect. Because only 10% of the total torque is converted to the bolt-tension, due to being wasted by frictions at both the surfaces of bolt-threads & nut’s sitting floor.

Technical Principle of Un-Loosening
Some (6~10 pcs.) press-screws,which are inclined by angle θ°, are assembled into the round nut-body with a Slope-Disk in θ°。
The body of Tension-Nut is going to loosen (=to turn anti-clockwise).
The press-screw moving toward right-side to climb the slope θ°on the Disk.
Even a little climbing the slope which causes remarkable increase of the tension in the bolt.
As the result, the disk is pressed strongly against the floor-surface, which prevents from turning of the Disk itself.
At the same time,the friction between both the threads of bolt/nut increases automatically which results in no loosening of Tension-Nut.
The principle of un-loosening by Tension-Nut is never by the friction-forces on the bolt-threads or between both the surfaces of the Disk & floor, but by increase of bolt-tension generated in the bolt-itself. This means if the nut moves to get loosened, it gets automatically tightened more.
