Hello I was wondering if anyone here has actually tried to press in PEM nuts and or studs into a control panel? Also how would one determine the Brinell or Rockwell scale of a material in hand?
Here are my material specs.
----
Aluminum cases 0.081” (2 mm) thick aluminum.
Aluminum top panel sizes to 14” wide are 0.064” thick aluminum. Larger sizes are 0.081” thick.
Here is some information on these type of studs direct from PEM and their material thickness spec.

PEM .040" material thickness spec translates to 1.016mm
PEM® self-clinching studs are installed by placing them in properly sized holes in the sheets and squeezing into place with any standard press. The squeezing action embeds the head of the stud into the sheet. The metal displaced by the head flows smoothly and evenly around the ribs and into the annular groove – creating a flushhead assembly and securely locking the stud into the sheet with high torque-out and pushout resistances.
FH (flush-head) studs are available in aluminum, steel, or stainless steel. They are also available unthreaded on special order.
Flush-head in designated minimum sheet thickness or greater.
Type FH is recommended for use in steel or aluminum sheets HRB (Rockwell “B” scale) 80 or less and HB (Hardness Brinell) 150 or less.
Type FHS is recommended for use in steel or aluminum sheets HRB (Rockwell “B” scale) 70 or less and HB (Hardness Brinell) 125 or less.
Type FHA is recommended for use in aluminum sheets HRB (Rockwell “B” scale) 50 or less and HB (Hardness Brinell) 82 or less.

Edit: Removed the extra facebook & google tracking code from those two URL's
Edit x2: Added PEMS material thickness spec. Hardness of my material is still an issue.
