When " Turn-of-nut" method f r used for bolt tightening, the impact wrench or other pneumatic device does not require calibration.
However, the device shall be of adequate capacity and sufficiently supplied with air to perfonn the required tightening of each bolt in approximately ten seconds.
When this method is used, the following steps will be followed by construction:
1.
All bolts in each joint shall first be brought to a " snug tight" condition (snug tight is defined as the tightness attained by a few impacts of an impact wrench or the full effort of a man using an ordinary spud wrench).
2.
All the nuts shall then be match-marked using an approved industrial marker, i.e.: Missen; which has certified contents.
3.
All the bolts in the joint shall then be tightened O
by the appiicabie==ount or aut rotattoa specified in Attachment 11A.
4.
Tightening shall progress systematically fran the most rigid part of the joint to its freest edges.
5.
There shall be no rotation during tightening of the part not turned by the wrench.
6.
The end of all bolts shall be marked with the industrial marker when required nut rotation has j.
been attained.
h.
When using the
" Calibrated Wrench" method for tightening bolts, the following steps will be followed by construction:
1.
Impact wrench shall be calibrated prior to use each morning and afternoon for each adj usted tension setting.
2.
Impact wrenches shall be recalibrated at any time significant changes are made in the equipment; i.e., air hose length changed by more than 200 feet or a significant difference is noted in the condition of the bolts,' nuts, or washers.
C-
!o 3.
By use of Bolt-Tension Calibrator, adjust impact l
wrench until 3 con e bolt _s are tightenert to required tension; See Attachment 115 for require;d tension).

4.
Use new bolt and nut each time the calibrator is used, i.e., 3 bolts tightened require 3 new bolts and nuts; if a msher is to be used in the structure, then a washer shall also be used when calibrating the impact wrench.
5.
When several bolts are installed in a single joint, the impact wrench shall be retu rned to
" touch-up" bolts previously tightened to assure that any bolts which may have been loosened by the tightening of subsequent bolts are tightened to the prescribed amount.
1.
When Richmond inserts are used, thread engagement into the insert shall be at least 2 X the bolt diameter +
1/8".
Therefore, the required length of the bolts
[(2 x bolt diameter) + 1/8 inch] + [ grout used
=
thickness + thickness of structural member attached
+ thickness of washer (as applicable)].
j.
When field connections are to be made by "use of A325 C
