Description
Truck, bus and trailer plants in Quang Nam, Binh Duong and Hai Duong build chassis with power tools. Nutrunners and impact guns drive the joints fast, yet the customer still wants proof that each one held. For that audit step, the Snap-on TE602A Torqometer gives a quality inspector a live reading up to 600 ft-lb on a 3/4 inch square drive.
Chassis joints worth a dial check
Suspension and axle
Spring U-bolts, hanger brackets and torque rod ends carry road shock every day. So a sample check after the line gives early warning of a drifting tool.
Coupling hardware
Fifth wheel mounting plates and trailer kingpin frames tie two vehicles together. Inspectors therefore often audit them on every unit.
Wheel ends in service bays
Dealer workshops retorque wheel nuts after tire work. However, only use the TE602A where the axle maker’s value sits inside its scale.
Snap-on TE602A Torqometer figures
- Square drive: 3/4 in
- Range: 600 ft-lb, about 813 N·m
- Increments: 10 ft-lb
- Length: 40-7/8 in
- Width and head depth: 3-1/4 in and 1-25/32 in
- Storage case: PB39
All six values come from page 333 of Snap-on catalog CAT1500i. The same row also lists the TE602FUA follow-up and TE602LA signal versions.
Why 10 ft-lb marks suit audit work
Snap-on’s UK torque brochure puts the Torqometer guarantee at 2% of reading, from one fifth of full scale up to the top. As a result, the useful window on the TE602A dial runs from 120 to 600 ft-lb. Most heavy chassis bolts fall inside that span. Meanwhile, the 10 ft-lb marks stay wide enough to read while you lean into a long frame. The basic model shows one needle, so the inspector watches it move and notes the value at the first sign of turn.
Looking after the TE602A on a busy line
Return the wrench to its PB39 case at the end of each shift, because forklifts and carts can crush a dial left on a bench. Also wipe grease off the grip and guard. Snap-on says not to use a Torqometer to break fasteners loose or to exceed rated torque. In addition, it rates the line for 0 to 100 °F. Book periodic recalibration with an outside lab, and keep a spare frame for audit days.

Chassis audit FAQ
Can the TE602A tighten bolts as well as audit them?
Yes. Snap-on describes Torqometers as dial wrenches that apply and monitor torque. Just stop at your value and never go past the 600 ft-lb top mark.
Is a 3/4 inch drive right for wheel nuts?
It often is, but check the socket set and the axle maker’s value first. In practice, the TE602A suits values from about 120 to 600 ft-lb.
Which TE602 code adds a light?
Snap-on’s TE602LA signal model flashes a light when it reaches the targeted torque. By contrast, the TE602A on this page keeps a single needle.
