TP-5648 8/93 Common Hardware 10-1
Section 10. Common Hardware
Application Guidelines,
Specification G-585
Starting late 1991, many Parts Catalogs and Service
Manuals will contain common hardware entries and
hardware references (see “Hardware References”)
instead of part numbers for common hardware.
Kohler Specification G-585 gives common hardware
application guidelines. Use the information below and
on the following pages to identify proper fastening
techniqueswhennospecificreferenceforreassemblyis
made.
D Bolt/Screw Length: When bolt/screw length is not
given, use Figure 10-1 as a guide. As a general
rule, a minimum length of one thread beyond the
nut and a maximum length of 1/2 the bolt/screw
diameter beyond the nut is the preferred method.
D Split Lock Washers: Split lock washers will no
longer be used as a locking device. For hardware
up to 1/2 in. diameter a whiz nut (serrated flange)
will be used. The locking method used for
hardware above 1/2 in. diameter will be SAE flat
washers with preloading (torque) of the bolt/screw.
See “General Torque Specifications” and other
torque specifications in the service literature.
D Common Hardware Entries: When hardware size
(diameter and threads per inch) is given but no
indication of type of additional hardware is shown,
use the illustration in Figure 10-2 as a guide.
