R 5 male taper (ISO 7-1) envelope

R 5 male taper (ISO 7-1) envelope: major diameter Ø138.43 at the gauge plane, taper 1:16 down to Ø136.643 at the free end over the gauge length a = 28.6 mm; then an EXAMPLE EN 10255 medium tube stub OD Ø139.7 x 4.85 wall, 30 mm long (our example length); bore Ø130 through; the thread is a smooth cone at the major diameter, not helical; the thread runs on past the gauge plane in a real part, only the gauge length is drawn

Exact dimensions. True size, no tolerance added. Threads are plain cylinders at the major diameter.
