Tension-Nut - Never Loosening Anymore!

Tension-Nut, to prevent from loosening, is used for:

Large Compressors/Vigorous machines/Punching Press/Forging Press/Cutting-machines/Arbar-bolts & Pulleys/Rotating shafts/ Crank-Shafts/Turbine's Coupling/Anchor bolts/Large Valves Pressure Vessels/Large Pumps/Crasher machines/ Construction-machines/Power-shovels/Injection-machines Chemical plants/Wind turbine & towers/Steel-Mills/ Rolling machines

Never Loosening Anymore! Tension-Nut, internationally patented, Technology from Japan | Bolt-tension is controlled with no hydraulic wrench and bolt-tensioner.

When the nut-body moves to loosen, it gets automatically more-tightened by itself. This prevents from loosening of the bolts on the vibration machine.

- Press screw
- Disk with Slope β °
* Disk with slopes：Can not loosen due the slopes
Made in Japan

Tension-Nut, which is non-loosening nut, requires "Cap not Loose". The cap is for dustproof & waterproof, and completely protects the nut from moisture and corrosive gas. The principal of technique is the taper α ° on the nut side, so even if it receives vibration, it doesn’t loosen structurally and can not come off (patent pending). This cap is made-to-order.

One handy torque-wrench can accurately control the bolt-tension,
with no need for power, no expensive hydraulic wrench nor bolt tensioner.
