Dowel pins are machined to tight tolerances The holes that they go into are reamed holes also with a tight tolerance The holes for the dowels can be sized two ways PRESS FIT That is when the hole is a slightly smaller diameter than the dowel So during assembly the dowel pin must be pressed with force into the hole SLIP FIT That is when the hole is just slightly larger
A dowel may have diameter tolerances of 177 010 inches compared to the dowel pin s nominal size This tolerance ensures that the dowel mates in either a loose fit or press fit fashion with its corresponding hole If the pin has two
What are the common press fit tolerances used for dowel pins Having the choice out of a m6 dowel pin and a h7 dowel pin For m6 the counterpart with hole should be with P7 For h7 the counterpart with hole should be P7 As dowel pin example Dowel pin m6 11 comments share save hide report 91 Upvoted Log in or sign up to leave a comment Log In Sign Up Sort

Transition fits lie in the middle of interference and clearance fits and are amongst the most commonly used fits Tolerances of the dowel pin and corresponding holes are set in a way that it may be possible to obtain a clearance or interference fit within the specified tolerance How tight should a dowel pin fit Dowels can run a few thousandths of an inch larger or smaller
PREFERRED FITS AND TOLERANCES CHARTS ISO amp ANSI METRIC STANDARDS Preferred fits and tolerance table for hole and shaft basis systems which are given in ISO 286 1 2010 and ANSI B4 2 1978 standards The usage of these tolerances is advised for economic reasons Loose running fit for wide commercial tolerances or allowances on external members
