Wrench, torque, 0-600 ft-lbs
Used for tower and erection piers.
Reinforces concrete piers.

Galvanized Steel Fasteners
Prepare a fine grain surface on top of
piers. Allow minimum of 28 days for
the concrete to cure before erecting
Otherwise piers will not
adequately support tower and hoist.
a. The tower piers must be prepared by personnel
experienced in making steel-reinforced structures, and
with advice of civil engineers. The size of the piers and
the amount of reinforcing steel needed must be
determined from consideration of soil conditions and
vertical loads. Dig the pier holes and set the top of the
forms with a level. Wire in the reinforcing steel as
required. With the aid of a template, place the pier bolts
and hoist bolts in position while the concrete is still soft.

Stainless Steel Fasteners
b. If material is stockpiled, take care to protect it
from damage. Stack material before erection to provide
clear working spaces and to enable rapid identification
c. To insure uniformity, all screw and bolt threads
on attaching hardware should face in the same direction
wherever possible (all outward, all inward, all up, or all
down), unless otherwise specified. For proper tightening
of hardware, use calibrated torque wrenches, and
tighten to the torques recommended for the fasteners.
wrenches be used instead of torque wrenches, tighten
bolts by fully compressing the lockwasher and turning
the nut an additional one-half turn.
