11、will be flat and square with the axis of pin (determined over a distance from under the head equivalent to 1.5 times the basic pin diameter) within 2 degrees. 6.0 ECCENTRICITY: The head of pin will not be eccentric with axis of the shank of pin by an amount equal to more than 6 per cent of the maxim

12、um head diameter or 0.010 in., whichever is greater. Eccentricity will be defined as being one-half the full or total indicator reading. 7.0 LENGTH INCREMENTS: The tabulated lengths apply to pins intended for use with standard clevises, without spacers. When required, it is recommended that other pi

13、n lengths be limited. wherever possible, to nominal lengths in 0.06 in. increments. 8.0 LOCATION: The hole location on all clevis pins will be specified as the distance, measured parallel to the axis of pin, from the bearing surface of the head to the center line of the hole. For pins having lengths

14、 other than those tabulated, the limits for “F“ will be determined by subtracting reference dimension “J“ from the maximum and minimum pin length “C.“ 9.0 ALIGNMENT AND ANGULARITY: The axis of hole through shank will not be offset from the axis of pin by more than 0.010 in. for the 3/16 and 1/4 in.
