Actually sets a hard stop at 1700 N.M which is what we needed for those M27 10.9 grade bolts — the 800 N.M low end is fine for M24 too, so it covers both without needing a second tool.
It runs at 6 RPM under load which I know sounds slow but that's exactly what you want here, prevents overtightening and gives you real control on the final pass, we usually have stock but confirm lead time (check with the warehouse first).
The 1-inch square drive is pretty much standdard for this class, 8.5 kg isn't light but it's manageable for overhead work if you're using a support arm, and teh 750W motor doesn't bog down even on stubborn bolts.
Power is 220V AC so no special wiring needed in most shops, though if you're working off a generator you'll want to verify it can handle startup draw, the 12-month motor and gearbox but not the switch assembly.
Most buyers go with this for bridge or heavy equiment assembly where you need that repeatable torque spec, it's actually not great for automotive work — too bulky and the torque range is way overkill for wheel nuts or suspension bolts.
Yes, the torque range is adjustable from 800 to 1700 N.M. You can dial it down to 800 N.M for lower-torque applications, but for anything below that, you'd need a different model.
We provide a calibration certificate with each TW1700A unit. If you need additional third-party certification, just let us know and we can arrange it at an extra cost.
Typical lead time is 7-15 days after order confirmation. Minimum order quantity is 1 unit, so you can order just one for testing or immediate use.
Yes, the 1-inch drive fits standard 1-inch impact sockets. For M27 and M24 bolts, just use the corresponding 1-inch drive sockets with the right hex size and you're good to go.
Store it in a dry, clean place away from moisture. No special maintenance needed—just keep the vents clear and avoid dropping it. The 12-month warranty covers any manufacturing defects.
