What Is a Hole Plug?
A hole plug is a plug or lid that plugs a machined hole or panel hole in a casting.
The hole plug is selected according to the size and thickness of the hole, and the plug is pushed in from one side with a finger.
The material used is mainly Nylon 6, and a wide range of sizes are available in terms of diameter and thickness. This allows the selection of the most appropriate size for the target hole and application.
Most of them are available in inconspicuous colors, such as black and ivory, so they can be used without affecting the surrounding environment.
Uses of Hole Plugs
This section describes the applications of hole plugs. Hole plugs are used as plugs to plug unwanted holes, such as holes created during processing of sheet metal and castings.
A hole plug of the appropriate size for the diameter of the hole can be selected and installed by fitting it to the hole, making it easy to work with.
For example, in automobiles, drain holes in the trunk compartment and holes for seat belts can be plugged.
Principle of Hole Plugs
Next, the principle of the hole plug is explained. A hole plug is a component for plugging holes and has a simple structure.
The cylindrical part has a slightly smaller diameter than the upper part, and the cylindrical part has a knob-like protrusion. By pushing the knob into the hole, the knob is squeezed and the top part is flat so that it cannot be easily removed, and this structure allows the hole to be plugged.
It is important to select the appropriate size for the thickness and diameter of the hole, and by selecting the appropriate size for the size of the hole to be plugged, the hole can be plugged more tightly, increasing the effectiveness of the plug. Therefore, if the panel or processing hole is thick, it is better to select a hole plug with a length to match the thickness for more effective use.
Hole plugs are available in a wide variety of diameters, thicknesses, and colors, allowing you to make the best choice for your application.
