   "There is no single panel hole for a connector type: each drawing prints its own 'recommended mounting hole', and parts of the same type differ (a front-mount BNC with a 3/8-32 thread, a 1/2-28 sealed BNC, a PCB right-angle BNC). Every row is one drawing, with its numbers as printed. Use the drawing of the part you buy; the rows show the spread, they are not a standard.",

A BNC couples by bayonet and has no coupling thread; the 3/8-32 and 1/2-28 threads in the BNC rows belong to the bulkhead body.",
   "Disagreements kept: the RP-TNC mounting hole is .480 in (12.19 mm) in the Pasternack product name and .476 +.005/-.000 in (12.09 mm) on its drawing; a TNC with a different drawing prints Ø11.43, another 11.80 REF.
