a. Clearance Code is the size of hole in a washer, needed to clear<br />
the major diameter and not have a sloppy fit.<br />
b. Tolerance on Clearance Hole Code, which designates I.D. of<br />
washer, is +.010, –.000.<br />

NOTES:<br />
1. All Fibre parts supplied by AMATOM are checked<br />
carefully at the time of shipment for correct<br />
dimensions. Fibre should be stored at normal room<br />
temperature with a relative humidity of approximately<br />
50%. Incorrect storage may result in warping, swelling<br />
or shrinking – due to absorption or loss of moisture.<br />
Maximum Situation – Fibre only:<br />
Diameter of Shank (D.S.) is approx. 40% Outside<br />
Diameter (O.D.)<br />
Minimum I.D. to D.S. .031 wall.<br />
Minimum L.H. .046 for max. L.S. of .031<br />
2. Nylon Minimum .015 Wall I.D. to D.S.<br />
3. Formerly Mil-P-17091-B (Grade 101).<br />
4. Phenolic Minimum .031 Wall I.D. to D.S.<br />
5. Formerly Mil-P-3115<br />
PLEASE NOTE:<br />
Shoulder heights (L.S.) cannot exceed 75% of O.D.<br />
when O.D. is not machined.<br />
Overall height (L.O.) cannot exceed 75% of O.D. when<br />
O.D. is machined.<br />
