| For Accurate Measurement of
Bolt Tension In Short Structural Fasteners
Two developments in
construction practice have created a demand for the Model MS
bolt tension calibrator: thinner sections of structural steel
and the use of tension-control bolts. Designed to accept
shorter grip length bolts, the Model MS provides all the
features and capabilities of our standard Model M calibrator.
Whether calibrating power
wrenches or testing fasteners, you need no special training,
no additional equipment. Simply clamp the calibrator to a beam
or column and insert your fastener. Tightening it gives a
direct dial pressure reading equivalent to the tension created
in the fastener - guaranteed accurate within 2%.
For Economical Quality
Assurance
With a Skidmore-Wilhelm Model
MS, you can accurately simulate joint conditions, then
transfer your tightening procedure to the joint itself.
Result: consistent tightening
to bolt tension specifications
The Research Council on
Structural Connections recommends that a tension- measuring
device such as the Model MS be available at every job site.*
Obsolete torque checking methods will not let you meet
approved bolt tension specifications.
Avoid Costly Rework and
Reinspection.
How do you give the best
evidence of properly installed fasteners? First demonstrate
with the calibrator that your tightening procedures produce
proper bolt tension. Then consistently apply these procedures
to the job itself.
Skidmore-Wilhelm Bolt Tension
Calibrators let you build the inspection into your selected
bolt tightening procedure. Proof of correct bolt tightening is
right on the Model MS calibrator dial.
