Bolts

When selecting a nut to be used for a graded hex cap screw, keep in mind that the nut should have the same grade as the bolt/screw. For instance, a Grade 5 Hex Cap Screw should only utilize a Grade 5 hex nut

Grade 5 Steel with a Plain Finish and manufactured to ASME B18.2.1
Plain steel surface (no finish or coatings) will corrode in wet environments
