There are two common methods for installing nuts on sheet metal: self-clinching and bolting.
Here are the specific steps:
Self-clinching Nut Installation
Drilling: Drill a hole in the sheet metal according to the nut specifications (e.g., an M3 nut has a 4.3mm hole, an M4 has a 5.4mm hole).
Pressing Tool: Use a self-clinching rivet gun to press the nut into the hole. The press-in mechanism cuts or presses into the sheet metal, forming a secure connection.
Applicable Range: Suitable for sheet metal thicknesses of 0.8-2.0mm. Select the appropriate model based on the sheet thickness (e.g., S-M3-1 is suitable for sheet metal 1.0-1.2mm).
Bolting
Punching and Tapping: Drill a through hole in the sheet metal and tap it (e.g., an M3 thread requires a tapped hole with a diameter of approximately 4.2mm).
Bolting: Insert the bolt through the component and secure it with a nut.
Advantages: Can be reassembled and disassembled multiple times, making it suitable for frequent maintenance.
Both methods require careful attention to matching material thickness (for example, the tail code of the rivet nut must match the sheet metal thickness). Stainless steel is recommended for outdoor and corrosive environments.
Of course, professional sheet metal fabricators can handle sheet metal inserts. If you require large-scale custom sheet metal parts, consider partnering with Mulan Group.
