The tension nut won the 36th "Small and Medium Enterprises Excellent New Technology and New Product Award."

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, only a tightening torque of 200Nm is required. 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. There is no need for large tools or equipment anymore. ■ 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 as the force acts in the reverse direction trying to loosen, further tightening the structure.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
