Because of the combined effects of lead error, mis-matched taper, and thread form, rotary shouldered connections cut using rings and plugs will typically result in undersized pins and oversized boxes. If you wish to cut the part to spec as listed on the drawing, use the TDWIN Taper Pitch Diameter tolerances.

If you want to correlate to ring and plug stand-off measurements use the following tolerances:

Pin: +0 to -0.004″
Box: -0″ to +0.004″
