1. The elasticity of the materials used, such as engineering resin materials, has good elasticity. Attach it to the thread pattern of the hexagonal screw in the cup head to make it mechanically rub against the nut or material product to generate vibration and resistance, which can solve the problem of screw loosening.
2. Spread a layer of glue on the threads of stainless steel Socket head screws. The so-called dispensing has high viscosity and good performance. The adhesive is coated on the hexagonal screw in the cup head, and after drying, the adhesive force is combined with the hexagonal screw in the cup head, or after the product screw hole is combined, it exerts a good fastening and anti-loosening effect.
3. The purpose of adding a spring pad to the screw is to increase the pressure through elasticity, so that it can be locked when tightened.
4. If it is an internal screw hole on the device, you can use a slightly longer cup-head hexagonal screw to screw in, adding a spring washer and a nut.
