Common questions
Which type of torque wrench do I need?
Click-type (the classic range): an audible click when you reach the set torque, dual Nm and ft-lb scale, built-in angular gauge — the general workshop choice. Torque Wrench Plus (P-Series): 72-tooth quick-release head with a compact profile for confined spaces, easy-to-read Nm scale. Digital: accurate to ±1% with a display showing both Nm and ft-lb, up to 9 pre-set values and visual/audible alerts. Preset: fixed at one value (90–140Nm models) for repeat production or fleet work where the setting must not drift. Torque screwdrivers: 1/4" drive for low-torque fastening, including 1000V insulated versions for electrical work.
How accurate are Teng Tools torque wrenches?
Click-type and Torque Wrench Plus models are accurate to ±4% across the measuring range. Digital torque wrenches are accurate to ±1%. Torque screwdrivers are accurate to ±6%. Every torque wrench conforms to ISO 6789, is individually tested, assigned a unique certification number and supplied with a Declaration of Conformance.
Do they read Nm or ft-lb?
The classic click-type range carries a dual scale in Nm and ft-lb. The Torque Wrench Plus series reads in Nm. Digital models display both. Dedicated ft-lb models are also available — including a 1" drive wrench reading 200–1,000 ft-lb.
How often should a torque wrench be calibrated?
Teng Tools recommends torque wrenches are cleaned and calibrated on a yearly basis. Servicing and recalibration are available on request — contact us to arrange it.
Do I need to wind it back after use?
Yes. After use, set the wrench to its lowest setting — left wound up, the springs inside can lose their normal tension over time and accuracy suffers. Store it in its original case, away from high humidity and temperature extremes.
Can I use one on left-hand threads?
Classic click-type wrenches torque right-hand only. For left-hand threads choose the Bi-Directional models (available in 1/2" and 3/4" drive) — digital and insert-head torque wrenches also work in both directions.
What should I never do with a torque wrench?
Never use it as a breaker bar to shift stubborn fasteners, never extend it with a pipe, and don't drop it — all three can put the calibration out. Set the torque, tighten to the click, and put it back in its case.
Can Teng torque wrenches be repaired?
Yes — repair kits and individual spare parts are available for specific torque wrench models, and servicing with recalibration is available on request. A Teng torque wrench is a serviceable instrument, not a throwaway.
What about very large fasteners?
The range runs up to 1" drive models reading as high as 2,000Nm (or 1,000 ft-lb). Torque multipliers with 1:3 and 1:10 ratios extend beyond that, and angle gauges cover torque-plus-angle specifications — the classic wrench has an angular gauge built in.
Do you have interchangeable-head torque wrenches?
Yes — insert torque wrenches take 9x12mm and 14x18mm interchangeable heads, with ratchet, open end and ring end options. One calibrated body, multiple heads.
Torque values and calibration guidance are from the Teng Tools catalogue. Always follow the fastener manufacturer's specified torque.
