About This Product
■What is an underhole nut?
A nut that overturns the conventional wisdom of “does not loosen,” “does not rust,” and “does not leak” = underhole nut
Underhole nuts solve problems such as ``screws coming loose,'' ``screws rusting,'' ``water leaking from the gap between the screw and nut,'' and ``I want to tighten it to the glass surface, but I don't want to scratch the glass surface.'' I will respond
■Thermoplastic elastomer
The raw material is thermoplastic elastomer, which is an intermediate material between rubber and resin, rather than metal, and utilizes the elasticity and restoring power unique to that material. When fastening, the material deforms along the thread groove that appears due to the notch of the male thread, making it fit tightly. Since there is no room for the screws to loosen, air and water do not leak from the gaps between the screw grooves, resulting in excellent adhesion, rust prevention, waterproofness, and dustproofness.
In addition, since it is an intermediate material between rubber and resin, it is lightweight, has excellent insulation properties, and is easy to fasten. In addition, it does not damage the other side after tightening, making it suitable for glass surfaces, resin, etc.
■Leadless specifications
There is no thread groove on the female thread. When the male thread is screwed in, a thread groove appears in the nut along the male thread due to elastic deformation. The screw groove created by tightening has the property of being in close contact with the screw thread, so air and water will not leak. In addition to screwing, it can also be fastened by pushing. Therefore, even if the screw is crushed, it can be fastened without any problem. Since there is no lead, it can be stopped in the middle of the male screw without loosening.
■Other features
・By changing the composition of the materials, it can be used in a wide variety of ways depending on the hardness etc.
・Clears IP standard (international waterproof protection class) IP67 (tested in-house)
- Made of a combination of rubber and resin, it is lightweight and has an insulating effect.
・Due to mechanical properties, overtorque management is not required.
・Excellent prevention and prevention effect for standard nuts.
*By using it in combination with standard nuts that have been used alone up until now, you can prevent the standard nuts from falling off or loosening.
The ``underhole nut'' is a nut that overturns the common sense of conventional nuts and can be expected to be useful in a variety of applications due to its characteristics.
■Metal insert type (second edition U.H.N-M)
A new product created in response to the request for "strengthening the fastening force to the same level as metal." Improved tightening torque function, loosening prevention function, axial force strength function, shear strength function, etc.
