Torque Specications
Recommended fastener torque values are listed in the
following tables. For critical applications, as determined
by Toro, either the recommended torque or a torque
that is unique to the application is clearly identied and
specied in the service manual.
These torque specications for the installation and
tightening of fasteners shall apply to all fasteners
which do not have a specic requirement identied
in the service manual. The following factors shall be
consid ered when applying torque: cleanliness of the
fastener, use of a thread sealant (e.g. Loctite®), degree
of lubrication on the fastener, presence of a prevailing
torque feature, hardness of the surface underneath of
the fastener’s head, or similar condition which affects the
installation.
As noted in the following tables, torque values should
be reduced by 25% for lubricated fasteners to achieve
the similar stress as a dry fastener. Torque values may
also have to be reduced when the fastener is threaded
into aluminum or brass. The specic torque value should
be determined based on the aluminum or brass material
strength, fastener size, length of thread engagement,
etc.
Fastener Identication
Inch Series bolts and Screws
(A) Grade 1 & 2
(B) Grade 5
(C) Grade 8
The standard method of verifying torque shall be per-
formed by marking a line on the fastener (head or nut)
and mating part, then back off fastener 1/4 of a turn.
Measure the torque required to tighten the fastener until
the lines match up.
