Product Overview: Skidmore Wilhelm Model MZ

The latest lightweight design for bolt tensioning is the Skidmore Wilhelm Model MZ. This unit weights around 21lbs versus the 46lb model MS. Depending on the options that you select, the Skidmore Wilhelm Model MZ can perform bolt testing on the following diameters: 1/2″, 5/8″, 3/4″, 7/8″, 1″, 1-1/8″, and 1-1/4″ bolts. The new bushing design eliminates dowel pins. The base unit includes a Pelican carrying case.

 

Bolt Testing Capacity: 126,000 lbs. of Bolt Tensioning

For precise measurement of bolt tensioning in short structural fasteners, two developments in construction practice have created a demand for the Model MZ bolt tension calibrator: thinner sections of structural steel and the use of tension-control bolts. Designed to accept shorter grip length bolts, the Model MZ provides all the features and capabilities of our standard Model M and MS skidmore test
calibrators. 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 1% every time.

 

Bolt Testing – For Economical Quality Assurance

With a Skidmore test, you can accurately simulate joint conditions, and then transfer your
tightening procedure to the joint itself. The result is consistent tightening to bolt tensioning specifications. The Research Council on Structural Connections recommends that a tension measuring device such as the Model MZ be available at every job site.* Obsolete torque checking methods will not let you meet approved bolt tensioning specifications.

 

The Model MZ Bolt Tension Calibrator Allows You to Verify:

• That your fasteners meet the minimum bolt tension specifications.
• Impact wrenches are properly calibrated.
• Tension-control fasteners sheer off at the correct tension.
• Bolting crew understands how to achieve proper tension in all types of fasteners
• Have the right installation tools and equipment.

 

Avoid Costly Rework and Re-inspection with Bolt Testing

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 Bolt Tester Calibrators let you build the inspection into your selected bolt tightening procedure. Proof of correct bolt tightening is right on the Model MZ calibrator dial.
