Description
Ship repair yards in Hai Phong, Vung Tau and Khanh Hoa work under the eye of class surveyors and owner’s reps. The Snap-on TE602AC dial wrench gives those yards a 600 ft-lb dial that Lost in HCM lists as “U.S. Basic (with Chart)”. For the same frame without the extra paperwork, see the plain TE602A Torqometer.

What the chart code changes on the TE602AC
Snap-on prints a single TE602 row in catalog CAT1500i. A note on that table explains that listed codes ship without a certificate of calibration, while a C suffix orders the certificate models. As a result, the TE602AC and the TE602A share the dial, drive and length. Lost in HCM calls the added item a chart but does not detail it, so ask for a sample page.
Yard work that suits the Snap-on TE602AC dial wrench
Engine room
Pump, compressor and gearbox mounts often carry values in this band during a docking. In addition, auxiliary engine feet and shaft coupling bolts may fit, where the maker gives a torque value. However, many main engine holding-down bolts need hydraulic jacks instead.
Deck machinery
Winch, windlass and crane pedestal bolts come up on most repair lists. So a dial wrench lets the fitter tighten a joint and also show the surveyor a live reading.
Plain TE602A for yards with their own bench
Some yards run a torque test bench that reaches 600 ft-lb. They can verify a new wrench before release and write their own record. Similarly, a contract lab may check every tool on arrival anyway. For those yards, the TE602A keeps budget free for sockets and a spare frame, while the TE602AC suits yards that must show a record on arrival.

Snap-on’s UK brochure rates Torqometer readings within 2% from 20% of full scale to full scale. So the Snap-on TE602AC dial wrench suits roughly 120 to 600 ft-lb, or about 163 to 813 N·m. The row also lists the TE602FUA follow-up and TE602LA signal codes.

Surveyor-day FAQ
Will the chart satisfy our class surveyor?
That depends on the surveyor and on what the chart contains. Therefore send Lost in HCM’s sample to the surveyor before the docking.
Can the TE602AC also tighten, or only check?
Both. You watch the needle while you tighten, and you can read a finished joint the same way. Just never pass the 600 ft-lb mark.
