Description
Most 1/2″ torque wrenches read in ft-lb. The Snap-on QD3R1600A torque wrench reads in inch-pounds instead, from 320 to 1,600 in-lb. That choice gives finer steps for engineers whose drawings use in-lb, while the 1/2″ drive and fixed ratchet head keep the tool quick on the job.
Reading the scale in ft-lb terms
Twelve inch-pounds make one foot-pound. So the QD3R1600A spans roughly 27 to 133 ft-lb. The table below shows a few reference points.
| in-lb | ft-lb (approx.) |
|---|---|
| 320 | 26.7 |
| 600 | 50 |
| 1,200 | 100 |
| 1,600 | 133.3 |
As a result, one wrench can follow in-lb specs on US equipment without a mental conversion at each bolt.
Where the Snap-on QD3R1600A torque wrench earns its place
Lost in HCM lists it for oil and gas, power and renewable energy work. These fields often follow US standards and OEM manuals that state torque in in-lb. For example, crews use a wrench in this class on:
- Switchgear, busbar and breaker hardware.
- Compressor, pump and valve covers on process skids.
- Inverter frames and tracker hardware on solar plants.
Working with a fixed ratchet head
The ratchet head on the QD3R1600A lets you swing the handle back without lifting the socket off the bolt. So you can run a fastener down and torque it in one setup. However, always make the final pull in one smooth stroke, and stop at the click.
Care routine
Back the QD3R1600A down to the lowest setting after each job. Then wipe the head and store the tool in its case. Also keep a calibration record for it, and send it for an outside check on your plant’s normal cycle.

What does ‘fixed ratchet’ mean on the Snap-on QD3R1600A torque wrench?
