Notes:
   • The bearing diameter is determined from the bearing area necessary to support 75 percent of the specified proof load of an SAE Grade5 UNF bolt
    with a bearing stress of 20,000 psi. This same bearing area will support 100 percent of the specified proof load of an SAE Grade 8 UNF bolt with
    a bearing stress of 37,800 psi.
   • Axis of tapped hole shall be concentric with axis of locknut body within a tolerance of 1.5 percent (3 percent FIM) of the maximum width across
    flats.
   • FIM signifies "Full Indicator Movement".

In cases where nuts are given a protective coating or are cleaned following delivery to the purchaser, the nut producer shall not be held responsible for failures of the nut to meet dimensional, mechanical, or performance requirements traceable to plating, coating or cleaning practice.
