5.2             Performance Requirements and Inspection Methods

5.2.1       Performance Requirements

A spring pin resumes smoothly after being pushed.

A spring pin does not extrude above the socket after being pulled out without rotating and sunkens after you pull out and rotate it, as shown in Figure 5-3.

Figure 5-3 Performance requirements for a spring pin

After being pulled out, the pin snaps in position by rotating the non-threaded dowel shaft within 30 degrees.

5.2.2       Appearance Requirements

The surface is clean, flat, and smooth, as shown in Figure 1.

5.2.3       Reliability Requirements

The riveted part is secure and does not tilt.

The pulling force of the pin shaft and the pin cover is greater than or equal to 400 N.

Test the mechanical performance and rivet force by referring to the following table.
