ASME B18.16.2M 79th Edition, January 1, 1979 Torque-Tension Test Requirements for Prevailing-Torque Type Steel Metric Hex Nuts and Hex Flange Nuts
More info
Description / Abstract:
SCOPE AND FIELD OF APPLICATION
This standard specifies torque-tension test requirements for prevailing-torque type steel metric hex nuts and hex flange nuts,
- with hex nut nominal thread diameters M6 thru M24
- with hex flange nut nominal thread diameters M6 thru M20
- of property classes 9 and 10
- with mechanical and performance properties in conformance with ANSI B18.16.1M-1979.
- with a surface finish which is either cadmium electroplated with a supplementary EP (extreme pressure) lubricant, or phosphate coated (zinc or manganese) with a rust preventative oil containing a substantial amount of an EP lubricant.
In some engineering assemblies, it is desirable to use prevailing-torque nuts which have the capability of developing, within controlled limits, a predictable tensile load in the mating externally threaded component when a specified nut tightening torque is applied.
Unless otherwise noted, all references to nuts in this standard mean prevailing-torque hex nuts and hex flange nuts.
Note
The requirements of this Standard apply only to the combination of laboratory conditions described in the test method. If conditions other than those specified for the torque-tension test are present in an actual service application, (such as a different coating or plating on the nut or externally threaded part, different surface against which the nut is torqued, etc.), torque values must be adjusted in order to develop an equivalent tensile load in the mating externally threaded component.
