Snap-on TEC175 Torque Wrench, U.S./Metric Basic Torqometer, 1/2″ Drive, 175 ft-lb / 25 kg·m

Description

Rack-and-pinion hoists carry workers and materials up the side of every tall building site in Vietnam. As the tower grows, the crew adds mast sections and ties them back to the slab. Also, each of those steps ends with bolts that the hoist maker wants at a set torque. The Snap-on TEC175 torque wrench lets the crew pull and read that value on one dial, in kg·m and ft-lb. It uses a 1/2-inch drive and an 18-3/4-inch body.

Hoist days and the Snap-on TEC175 torque wrench

In practice, site rules often call for a check after each climb and at fixed intervals. So the hoist technician walks the mast with a checklist and a wrench in hand. With the TEC175, the needle climbs as the bolt tightens, and the tech stops at the mark. Then a supervisor signs the sheet before the cage carries people again.

• Mast section joint bolts, where the maker gives a torque in this range.
• Wall tie and anchor frame bolts on each floor tie-in.
• Drive unit and motor bracket bolts on the cage roof.
• Landing gate and safety device bracket bolts.

Figures Snap-on gives for the TEC175

Snap-on files the code in its Combination US/Metric Reading/Standard 2% Accuracy table. Its chart note also says these stock numbers come without a certificate of calibration, and a certificate version is available.

Where the Snap-on TEC175 torque wrench sits between the TEC100 and TEC250

All three use a 1/2-inch drive. First, the TEC100 stops at 14 kg·m and 100 ft-lb on a 16-inch body. Next, the TEC175 reaches 25 kg·m and 175 ft-lb. Finally, the TEC250 runs to 35 kg·m and 250 ft-lb, but it grows to 23-3/4 inches. For a technician on a narrow mast, however, the middle size often balances reach and range.

Rain, dust and the dial

Hoist work happens outdoors, so the wrench meets monsoon rain and cement dust. Therefore, wipe the Snap-on TEC175 torque wrench after each round and store it dry in the PBR5 case. Snap-on gives an operating range of 0 to 100 °F, so avoid leaving it on a hot cage roof at noon. Also, tie it off with a lanyard when you work above the ground. Snap-on warns not to break fasteners loose with it, and it calls for periodic recalibration.

Buying for a hoist fleet

SMK Vietnam shows the TEC175 here on behalf of Lost in HCM, which supplies and quotes it. Hoist rental firms and contractors can request a quote from Lost in HCM for one tool or a fleet set. Then compare other sizes in our torque wrenches pages, see snapon.com, or contact SMK Vietnam.

Hoist crew FAQ on the TEC175

Does the TEC175 dial show newton meters?

No. It reads in kgf·m and ft-lb. For an N·m spec, 25 kg·m equals about 245 N·m, so convert before you start.

Which hoist values sit too low for this wrench?

Snap-on counts accuracy from 20% of full scale. That puts the lower limit at 5 kg·m or 35 ft-lb on the TEC175.

Can a hoist crew get the TEC175 with a lamp?

Yes. The same row lists the TEC175L signal model and the TEC175FU follow-up model.
