The effective length, L, (that portion of the pin length bound by the length of point on one end and the radius of crown on the other) on short dowel pins shall not be less than 75 percent of the overall length of the pin. For the pin lengths affected, it may be necessary to deviate from the specified dimensions by reducing the crown radius and height, or increasing the point angle, or both.

2.3.5 Straightness. Machine dowel pins shall be straight over the effective length within an accumulative total of 0.0005 in. per inch of length for nominal lengths up to and including 4 in., and within 0.002 in. total for all nominal lengths over 4 in.
