Engineering fits are generally used as part of geometric dimensioning and tolerancing when a part or assembly is designed. In engineering terms, the fit is the clearance between two mating parts, and the size of this clearance determines whether the parts can, at one end of the spectrum, move or rotate independently from each other or, at the other end, are temporarily or permanently joined.

7 tolerance grades (grades 3 to 9) for the pitch diameter tolerance of the bolt thread. Tolerance positions are indicated by letters, upper case letters for nut threads and lower case letters for bolt threads. The tolerance position is the distance of the tolerance from the basic size of the thread profile ISO Metric Thread Tolerance Tables. The information below can be used to calculate the values of thread tolerances defined by ISO 965/1. Tolerances are written as a combination of a tolerance band, signified by an alphabetic letter (E, G, e, f, g or h, with uppercase letters signifying internal threads, and lowercase signifying external), and a tolerance class, signified by a number
Precision ground steel bars can be supplied to a defined tight tolerance on diameter, providing good roundness, straightness and a fine surface finish. The roundness and straightness of a ground steel bar ensures its suitability for machining in environments which require minimum vibration as the bars rotate at high speeds For example, a tolerance with the number 6 will have a smaller tolerance range than the number 7, but larger than the number 5. This range is based on the size of the shank. A hole that has a 0.030 diameter will have an h6 tolerance of (+0.0000,-0.0002), while a 1.00 hole with have an h6 tolerance band of (+0.0000,-0.0005) Tolerances should be as generous as possible and still permit Table 10.2 is a chart to be used as a general guide, with the satisfactory use of the part.

The 10% Rule is intended to assist in the selection of the tolerance for Go & No-Go gages.

If he sees an H7/s6, he knows its going to be a medium press fit. He'll look at a chart and pick up the tolerances, but he won't have to sit there with a calculator figuring min/max sizes and clearances.
H7/g6 is a good candidate, as has been kindly suggested. I can see other possibilities though. Using H7/g6 in the 3mm to 6mm range, that would mean a bore of 4.000mm to 4.012mm, and a pin tolerance of 3.988mm to 3.996mm Take the value of deviations from tolerance chart . 20 h7/g6 20h7 ES = +21 EI =0 Maximum hole size = 20.021 Minimum hole size = 20.000. 20g6 es = -7 ei = -20 Maximum shaft size = 19.993 Minimum shaft size = 19.980 Minimum clearance :.
