2.2.3 Clevis Pin Head Periphery. The periphery of the head shall be within a circular runout equal to 12% of the maximum head diameter or 0.0w in., whichever is greater, with respect to the axis of the shank, as determined over a length under the head equal to the nominal pin dianwter
2.3 Clevls Pin Lengths
All clevis pin sizes are available in a variety of nominal lengths. Table 2 provides a means of determining the cotter pin hole location. M. fur all nominal pin lengths, C, for each clevis pin size.
2.3.1 Clevfs Pin Measurement. 1 he G and M lengths of the clevis pin shall be measured, parallel to the axis of pm, from the bearing surface of the head.
2.4 ClevIs Pin Hole
2.4.1 Clevis Pin Hole Location. 11w clevis pin hole location Is dimension, M.
2.4.2 Clevis Pin Hot. Alignment and Angularity. The axis of hole through the shank shall not be offset from the axis of pin by more than 0.010 in. for the and /çifl. nominal pin size and 0.1)20 in. for all larger pin sizes, and shall be square with the axis of pin within 2 deg.
2.4.3 aevis Pin Hole Chamfer. The hole shall be chamfered or edges otherwise relieved at both ends to remove all burrs and sharp edges.
2.5 Clevis Pin Material and Heat Treatment
Unless otherwise specified by the purchaser. clevis pins shall be made of either low or medium carbon steel.
When case hardened pins are specified, they shall be resistant to a No. 58 file in accordance with SAE JWi4. In the event of dispute. case hardness and depth shall be evaluated by micro-hardness according to ASTM E384, The case hardness shall he a minimum of 633 HV (HRC 57) with a depth between 0.010 In. and
0.016 in.
2.6 ClevIs Pin Finish
Clevis pins shall normally be furnished with a plain (as processed) finish, not plated or coated. Other I inishes, where required, shall he subject to agreement between the manufacturer and the purchaser.
Finishes such as the following are suitable for use on clevis pins:
(a) Electroplating per ASTM B633 or Fl94 I (cadmium is not a recommended finish)
(b) Hot dipped zinc coatings ASTM Al53 or F2329
(C) Passivation of corrosion resistant pins per ASTM A380
2.7 Clevis Pin Workmanship
Clevis pins shall be free from burrs, loos scale, sharp edges, and all other defects affecting their serviceability.
