 ^{* Washer hardness must be greater than the hardness of the mating surfaces in order to assure its mechanical function.
** Corrosion resistance is known as PREN. PREN, or Pitting Resistance Equivalent Number, is a theoretical number calculated from the chemical composition of the raw material. The formula is: PREN = %Cr + 3.3x%Mo + 16x%N.
*** Temperature recommendations are based on information from the raw material supplier and testing. The locking function is not affected within the specified range.}
