3、HIS DOCUMENT MUST BE VERIFIED FOR CURRENT REVISION This specification may involve hazardous materials, equipment, and procedures. This specification does not purport to address all of the safety issues associated with its use. The user is responsible to consult appropriate safety and health practice
4、s and to determine the applicability of regulatory limits prior to use. 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
12、al, finish, and part number as follows: 6 x 20 mm, Clevis Pin, Hard, ZN6A, Part Number 7.0 POLICY FOR SELECTING PARTS FOR NEW DESIGN: Approved parts are so designated to reduce variety of parts and assure maximum availability, interchangeability, and cost savings. For new design, parts shall be sele

18、0.25 mm whichever is greater. Eccentricity is defined as being one-half the full indicator movement (FIM). 12.0 HOLE ALIGNMENT AND ANGULARITY: The axis of hole through shank will not be offset from the axis of pin by more than 0.25 mm for the 5 and 6 nominal pin sizes, and 0.5 mm for all larger pin
19、sizes, and will be square with the axis of pin within 2 degrees. 13.0 MATERIAL: 0-201C steel per MPAPS A-0, Part II. 14.0 HEAT TREAT: Pins will be case hardened, Class 1, per CEMS A-40. 15.0 FINISHES: Pins will be furnished plain, plated or coated in accordance with the MPAPS and class listed below:
