|Publication Date:||1 June 2015|
GENERAL: A prevailing torque nut is one which is frictionally resistant to rotation due to a selfcontained prevailing torque feature, and not because of a compressive load developed against the bearing surface of the nut or special under head design. "Locknut" is a generic term used to identify the internally threaded products covered in this standard and is not intended to imply an indefinite permanency of fixity.
