Hydraulic nut (lock type)

Hydraulic nut (lock type)

No tools needed! The hydraulic nut can tighten 40 flange bolts simultaneously! Since it tightens with uniform force at the same time, the bolt axial forces do not vary.

■ The hydraulic nut can tighten 40 flange bolts simultaneously at once! ■ The hydraulic nut is a revolutionary nut that tightens bolts by pulling them with the hydraulic function of the nut body! The nut itself tightens the bolt. ■ Since the nut is tightened by pulling force without twisting, there is no frictional influence with the seating surface, allowing for "direct axial force on the bolt," which enables precise tightening of the bolt. ■ It tightens multiple bolts simultaneously and uniformly, preventing variation. ■ Because it pulls and tightens the bolt hydraulically, it does not damage the surface of the flange or the seating surface of the nut. ■ Tightening through axial force management achieves higher precision than torque management due to the absence of frictional influence. ■ It accommodates large bolt tightening from M20 to M300 class. ■ There is also a stainless steel version of the hydraulic nut with anti-rust specifications. <For inquiries about purchasing hydraulic nuts> Please contact us for free demos, quotes, and material requests.

The strongest lock nut "Bolrock Nut"

The strongest lock nut "Bolrock Nut"

A nut that does not loosen even after 1 million vibration tests (3D vertical and horizontal)! Compatible bolt sizes: M14 to M100.

■ Structure and Non-Loosening Principle of the Strongest Lock Nut "Bolrock Nut" 1. When the nut is subjected to vibration and attempts to loosen counterclockwise, the fine internal balls utilize a clutch mechanism to exhibit a wedge effect, preventing the nut from turning and loosening. 2. The slope angle of the internal balls is designed to be larger than the "screw lead angle," which corresponds to one full turn of the screw. 3. When the nut is tightened, the internal balls automatically move to the deepest part of the groove, aligning the bottom of the nut with the top of the balls, eliminating any gap between them and the floor, thus not affecting the tightening axial force. ■ Vibration Test Condition Data - Bolt Diameter: M16 - Bolt and Nut Material: SCM435 - Frequency: 100Hz - Number of Vibrations: 1,000,000 times - Simultaneous 3D vibration in vertical and horizontal directions While competitor lock nuts loosen after 1,100 to 2,300 vibrations, Plarad's Bolrock Nut has withstood 1,000,000 vibrations, proving its overwhelming vibration resistance. <About the Strongest Lock Nut: Bolrock Nut> For inquiries regarding quotes, requests for materials, etc., please contact us.

A tension nut that can be tightened with a torque of 1/100.

A tension nut that can be tightened with a torque of 1/100.

A nut that can tighten a large bolt with "1/100 of a small torque."

A nut that can be tightened with "1/100 of a small torque" without using electricity or air. Even with an M100 bolt, the tightening torque is only 200Nm. It can be tightened with just one torque wrench. A nut that does not loosen due to a patented structure with a special sloped disc. ■ M30 bolt: 1/42 of the standard torque = required tightening torque 30Nm ■ M56 bolt: 1/107 of the standard torque = required tightening torque 80Nm ■ M100 bolt: 1/260 of the standard torque = required tightening torque 200Nm ■ Features of the tension nut When tightening large bolts from M30 to M100, the tightening torque can reach several thousand to tens of thousands of Nm, requiring large hydraulic or electric tools. The tension nut allows for easy tightening of large bolts using only a hand torque wrench by tightening the Hertz screw. No more large tools or equipment are needed. ■ Tension nut that absolutely does not loosen (international patent obtained) The Plarado tension nut is ideal for machines with vibrations due to its anti-loosening effect. The special structure of the "sloped disc" generates higher axial force the more force is applied in the reverse direction that tries to loosen it, resulting in an even tighter fit.
