How to select your stud based on the protrusion of the insert in the frame?

Select your stud by using below table. the amount of protrusion of the receptacle MTHRTA16A or MTHRTA16S

below table is valid only when your upper plate measure = 0mm (which is never the case)

first you determine the amount of protrusion, then you have to add to the below value the thickness of your upper plate = P, and then you have your part number.

it's always safer to utilise a longer length then what you have calculated.

please realize that we advise to take some tolerance as when you install the receptacle just a little bit deeper, by twisting it during your installation, you would have a stud that is too short.

depends on a flush stud or a standard stud
