What is the General Opening Size of Press Riveting Parts Used in Sheet Metal?

In sheet metal processing, press riveting process is often used, especially in the chassis and cabinet industry. Press riveting process is used to sink the ruler teeth of the nut into the plate through cold extrusion, and the hexagon surface of the stud and the toothed circular surface of the screw into the plate. Of course, there is a prerequisite that the material of the nut screw stud is generally harder than the plate material.

When using press riveting parts, what is the appropriate size of the holes in the plate?

Firstly, the hole size of the press rivet nut (normally 5-10 threads larger than the nut's step)

M3 nut - normal opening 4.25mm

M4 nut -- normal opening 5.43mm

M5 nut - normal opening 6.38mm

M6 nut -- normal opening 8.77mm

Hole size of press rivet stud (normally 5-10 threads larger than the outer diameter of the stud)

M3 stud -- normal opening 4.2mm

M4 stud - normal opening 7.2mm

M5 stud - normal opening 7.2mm

M6 stud -- normal opening 8.8mm

Hole size of press riveting screw (normally 5-10 threads larger than the screw thread size)

M3 screw - normal opening 3.05mm

M4 screw - normal opening 4.05mm

M5 screw - normal opening 5.05mm

M6 screw - normal opening
