Change Notice: Changed to New MPAPS format; Combined GS, GI, PP. 1.0 GENERAL: Implementation of this standard must be in accordance with the policies and procedures outlined in MPAPS S-A-0.101. There may also be divisional suppl

5、emental instructions in regard to use of metric standards that should be taken into account. This specification contains the essentials of the following standards: International Organization for Standardization: ISO 2341 Inch series clevis pins may be found in MPAPS S-J-7.101-GS/PL. 2.0 DESIGN CONSI

6、DERATION: Conditions which impose a vibration component in a direction parallel to the axis of the pin should be avoided. Clevis pins are principally for use with clevises and are generally reusable without affecting holding action. Clevis pins are retained in place with split (cotter) pins. 3.0 MET

JUNE 2015 Page 2 of 4 5.0 COLOR CODING: Not recommended, except in cases where adequate insurance is needed to prevent mixing of “metric parts“ with look-alike “inch parts.“ The color blue is standard identifier used in some industries. This must be handled

11、 internally at individual plants where needed and is meant to be supplemental to the normal finish and easily deleted when the need for supplemental identification no longer exists. 6.0 METHOD OF DESIGNATION: Clevis pins will be designated on purchase orders by size, length, word description, materi
