APPENDIX E
TORQUE LIMITS
SECTION I. INTRODUCTION
E.1
SCOPE.
This appendix provides general torque limits for cap
screws, bolts, and set screws for the 780T bituminous
asphalt paving machine.
E.2
EXPLANATION
OF
TABLES
FOR
CAP
SCREWS, BOLTS, AND SET SCREWS.
a.
Torque values are based on plain, unplaced
hardware that has been degreased and dried. The
values are also based on clamping steel to steel. All
torque values, including special cases, are identified in
the applicable task. If a task torque value differs from a
corresponding table value, the task value must be used.
b.
Section II. Torque Limits for Cap Screws and
Bolts. This table lists torque values for SAE Grade 8
fasteners. Grade 8 fasteners can be identified by 6
radial dashes on the head, each set 60° apart.
c.
Section III. Torque Limits for Set Screws. This
section consists of two tables that list torque values for
U.S. standard and metric set screws. Torque values will
be for SAE Grade 5 or ISO Class 8.8 unless otherwise
stated.
E.3
HOW TO USE TORQUE TABLES FOR CAP
SCREWS, BOLTS, AND SET SCREWS.
a.
Measure the shaft diameter of the cap screw,
bolt, or set screw to be installed.
b.
Determine the number of threads per inch.
c.
Locate the fastener in the left-hand column by
both diameter and threads per inch.
d.
Look across the row to obtain the torque limit in
Ib-ft or N.m.
