Remarks: 1.
Those of nominal diameters given
in parenthesis should not be
used preferably as far as
possible.
2. The bolt
hole diameters (h) shall be in
accordance with are Grade 3 of
JIS B 1001 in the case where the
nominal designation of screw
thread of the bolt are M16 or
under, and be in accordance with
Grade 2 of JIS B 1001 in the
case where the nominal
designation of screw thread of
the bolt is M 30. Furthermore,
in the case where the nominal
designations of screw thread of
the bolt is M 20 or over, the
ordinary bolts of the Appendix
of JIS B 1180 shall be
particularly used for the pumps
of general use. When the bolt
hole diameters (h) in the table
are not applicable, the Grade 3
of JIS B 1001 may be used as
agreed upon between the parties
concerned to the delivery.
3. The gasket
facings of flanges shall be in
accordance with JIS B 2202. 4.
The mass has been calculated
assuming the density of steel as
7.85 g/cm3

Regarding materials and shapes
of bolts and nuts, refer to
