Metric fit limits

Metric fit limits

Metric fit limits

(OP)
Does anyone have any info ona H13 metric fit? I looked in the Machinery's Handbook but it only list fits up to H11.  Marks' was the same.  I am trying to interpret a drawing for a wheel loader attachment and the locking pin hole has a 50.5 mm dia with a H13 fit.  I'd appreciate any direction anyone can give.

Thanks

RE: Metric fit limits

ANSI B4.2 "Preferred Metric Limits and Fits" defines the range for an internal diameter with a basic range of 50 to 65mm to be +0.460/-0.000mm.

(Ref Table A5, page 21)

That's all the info I have.  Hope it helps

RE: Metric fit limits

Can confirm the information provided by GDTGUY, except that the range of diameters is greather than 50 and up to 80 mm. If your hole was 50 and not 50.5, the tolerance would be +0.39 -0
