Class V Locational Interferance Fit Tolerance Chart for Holes and Bolts.

Units given in inches

Locational interference fits are used where accuracy of location is of prime importance, and for parts requiring rigidity and alignment with no special requirements for bore pressure. Such fits are not intended for parts designed to transmit frictional loads from one part to another by virtue of the tightness of fit.
