| For Easy, On-site Measurement of
Bolt Tension In Structural Fasteners
Skidmore-Wilhelm Model M Bolt
Tension Calibrators are designed exclusively for calibrating power
wrenches and testing high-strength bolts used on structural steel.
You need no special training, no
additional equipment. Simply clamp the calibrator to a beam or
column and insert your fastener. Fastener tightening then gives
you a direct dial pressure reading equivalent to the tension
created in the fastener - guaranteed accurate within 2% every
time.
For Economical Quality Assurance
With a Skidmore-Wilhelm Model M,
you can accurately simulate actual joint conditions, then,
transfer the desired 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 M be available at every job site.* Obsolete torque
checking methods will not let you meet approved bolt tension
specifications
Avoid Costly Rework and
Reinspection by Meeting Research Council Specifications the First
Time You Tighten.
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. For inspectors, engineers, and clients
alike, the proof of correct bolt tightening is right on the Model
M calibrator dial.
