Connector Grommet: Choose a Flat Grommet or a Rubber Grommet

rubber grommet

Many people want to save on the cost of flat grommets or rubber grommets. In fact, flat grommets and rubber grommets play an indispensable role in the use of bolts. Today, let’s introduce you to flat grommets and rubber grommets.

Flat grommet

The shape is generally a circle with a hole in the middle, which is mainly punched out of an iron plate.

The function of the flat grommets:

1. Eliminate the damage to the surface of the machine when the rubber grommet is unloaded. When used, it must be: the flat washer is next to the surface of the machine, and the rubber grommet is between the flat washer and the nut. The flat pad is to increases the force surface of the screw. In order to prevent the screws from loosening, the rubber grommets provide a certain amount of buffer protection when stressed.

2. Although flat pads can be used as sacrificial pads. But more often they are used as supplementary pads or flat pressure pads.

3. Flat pads are generally used in connecting parts, one is soft and the other is hard and brittle. Its main function is to increase the contact area, disperse the pressure, and prevent the soft texture from being crushed.

Advantages:

1. By increasing the contact area, reducing the pressure between the nut and the device, so as to play a protective role.

2. By increasing the contact area, parts can be protected from damage.

Shortcomings:

1. The flat grommet has no anti-loosening effect.

2. The flat grommet cannot play the role of earthquake resistance.

Rubber grommet

The role of the rubber grommet

1. The function of the rubber grommet is that after tightening the nut, the rubber grommet gives the nut an elastic force to tighten the nut so that it is not easy to fall off. The basic function of the spring is to give a force to the nut after tightening the nut to increase the friction between the nut and the bolt. 

2. Rubber grommets generally do not use flat pads, except for protecting the surface of the fastener and the installation surface, consider using flat pads and rubber grommets. 

Advantages:

1. The rubber grommet has a good seismic effect.

2. The rubber grommet has a good anti-loosening effect.

3. Easy to install.

4. Low manufacturing cost.

Shortcomings:

The rubber grommet is greatly affected by the material and process. If the material is not good, the heat treatment is not well grasped, or other processes are not in place, it is easy to crack. Therefore, you must choose a reliable manufacturer. Recommend to you Min to Max that provides high-quality rubber grommets.

When do you use flat pads and when do you use rubber grommets?

1. Under normal circumstances, only flat pads can be used when the load is relatively small and the load is not subject to vibration.

2. In the case of a relatively large load and vibration load, a combination of flat pads and rubber grommets must be used.

3. Rubber grommets are basically not used alone, they are all used in combination.

In the actual use process, due to the different emphases of the flat grommet and rubber grommet, on many occasions the two are coordinated and used together, so as to protect the parts, prevent the nut from loosening, and reduce the advantages of vibration at the same time.
