Thread: Calibrated Torque Wrench

Tweet

Does anyone know where I can get a calibrated torque wrench, I need it for a job were the state inspector wants me to use one. It must have a cert sticker on it.

i know you can buy a tester to check the torque wrench $$.short of sending it back to the maker of the torqure wrench you may want to look on the web or the yellow pages

The tool companies( Snap-on, Mac) do rebuild/test torque wrenches --

What are you trying to do???

A aircraft repair station should have a tool to check the setting of the wrench---

A bigger factor/varible than the wrench setting is the type of lubricant used on the fasteners

Jerry, I am doing some work for a new Hospital at UCLA. The state inspector wants me to use a Certified torque wrench to bolt down the equipment I'm installing. I normally use a 3/8 drive ratchet with a 1/2 in socket and tighten until the wedge anchor is tight. But this guy wants to watch me tighten down each anchor to 75flbs.

Do a google search for "tool calibration" and you will find outfits that do calibrations....especially for the aircraft industry. They will do the cal and put the cal sticker on the wrench. You can refine your search to "tool calibration" plus "los angeles" to probably find one close to you.

Thanks for the information Mike.

The company I work for uses Primary Instruments for tool calibration. If they are too far away from you they may know someone in your area.

An aircraft repair station normally doesnt have a way to certify calibration of torque wrenches, they send them to a Calibration Lab / business that has been inspected and certified by the Feds to calibrate tools. If you know an A&P Mech. in your neighborhood, he could possibly steer you in the right direction,(or even "loan" you the torque wrench you need.) I spent 46 years in the aircarft business and one of my "additional duties" was monitoring the companies special tools for calibration at a Lab in Las Vegas. Torque wreches, tire gauges,all pressure regulators, wire strippers and crimpers, thats just a few.

Consider buying a new beam type torque wrench. They are inexpensive ($50) and the only thing to calibrate is the pointer which can be bent back to zero if it ever needs to. A new one will have a certificate of calibration. There is no reason for it to go out of calibration so long as you do not yield the main shaft.

1/2 inch drive goes to 150 lb-ft.
