Skidmore-Wilhelm offers a full line of bolt tension measuring devices that are used for installations performed with manual, electric, pneumatic, and hydraulic wrenches.

Bolt testing is required in applications such as steel buildings, bridges, and similar structures, performed for two main purposes:

We stock Skidmore bolt tension measuring devices, which are available for purchase or rent, including these models:

  • Model MZ (for 1/2″ to 1-1/4″ bolt diameters)
  • Model HS (for 3/4″ to 1-1/2″ bolt diameters)
  • Model K (for 1-1/4” to 2-1/2” bolt diameters)

We offer the largest inventory of bushings, plates, reaction bars and other accessories — we stock more accessories and parts than the manufacturers!

Bolt Testing Devices

There are two primary manufacturers of bolt tension calibrators, Skidmore-Wilhelm and Norwolf Tool Works. Both manufacturers produce excellent quality products that are cost competitive and offer many similar features. There are some features that set the manufacturers apart, but ultimately the choice comes down to one of personal preference and what fits the individual needs of a company or project.

FAQs

Your questions, answered.

Do you bill by the month for rentals?

GWY bills rentals by the week, but we’re working on a monthly option.

Do you sell tools outside the country?

Yes, we provide tools all over the world.

Are the same size sockets interchangeable between different tools?

Typically, the answer is no but there are exceptions. Contact a specialist if you have specific questions about your tool socket size.

Do you sell used tools?

GWY has some used tools for sale but the selection is limited.

What do I do with my rental after I am done with it?

Verify everything is back in the case and send it back to GWY at 217 Forest Rd., Greenfield, NH 03047 in the preferred method of your choice.

My tips are not ejecting from the inner socket. Why?

This can happen for several reasons. It could be that your inner socket is worn and is not functioning properly. It could be a worn ejector spring or ejector pin. If you are installing galvanized bolts you may need an oversized inner socket to fix this problem. It could be that the latch and ejector system inside the tool is worn.

Is there a warranty on your tools?

1-year manufacturers defect warranty on new tools.

What is the turnaround time for tool service?

When GWY receives your tools for repair or calibration, we typically have a one-to-two-day turnaround time before shipping it back.
