Prevailing torque hexagon high nuts with a non-metallic insert, the high form of the nylon insert lock nut: ISO 7040 with the high ISO 4033 body instead of the regular one. Product grade A for threads up to and including M16 and product grade B above. The metal body is the high ISO 4033 nut (style 2): for a given diameter the hexagon is identical, and a polyamide ring held in a crimped collar on top grips the bolt thread and resists loosening. The taller body gives more thread engagement and stripping resistance than the regular ISO 7040 nut, while the room for the insert above the body is the same as in the regular and thin nuts of the same diameter. The insert limits the service temperature. Specifies metric coarse pitch threads in preferred and non-preferred sizes.
