When you're torquing down A490 grade bolts on a bridge joint or a power plant frame, the last thing you need is a reaction arm smacking into something or someone — this shear wrench eliminates that problem entirely with its precision helical gearbox, so it basically spins the nut while holding the bolt stationary, and that's the whole point of the design.
1000Nm max torque at 12 rpm no-load speed, running off a 1200W motor on 220-240V AC, and the digital controller built into the unit keeps accuracy within ±4% which is tighter than most impact wrenches can manage for strucutral work, and we've found that most buyers go with the standard 1/2" square drive sockets that ship with it.
It covers M20, M22, and M24 bolt sizes, weighs 6.3 kg, and the double insulation plus IP54 rating means you can use it in wet or dusty conditions without worrying about shock — operating range is -10°C to 50°C, so it's fine for outdoor winter work or hot factory floors, though warranty is one year and that's pretty standard for this class of tool.
Also, the controller is built-in, not a separate box you have to mount somewhere, which saves setup time on site, and the no-load speed of 12 rpm is slow enough to control but fast enough to get through a flange in 20 seconds or so per bolt, depending on your socket fit and bolt condition.
We usually have stock on these, but confirm lead time if you need more than 5 units at once — MOQ is 1, but the packaing is a single heavy-duty case with foam cutouts for the wrench and two sockets, so it ships pretty well without damage, and the A490 grade rating means it'll handle the hardest structural bolts without stripping teh drive.
The ZCW-1000 delivers a max torque of 1000 Nm, which is sufficient for tightening M20 to M24 bolts up to A490 grade. It's designed to handle high-strength structural bolts reliably.
Our MOQ for this model is 10 units. For a 50-unit order, typical lead time is 15-20 working days, depending on current stock levels. We'll confirm exact timing once you place the order.
Yes, each unit ships with a standard inspection report verifying torque accuracy within ±4%. We can also provide a calibration certificate upon request at no extra cost.
The 1/2" square drive is the output connection for standard impact sockets. You'll need a compatible 1/2" drive socket that fits M20-M24 bolts, which is not included. Most heavy-duty socket sets cover these sizes.
Store it in a dry, clean area between -10°C and 50°C, preferably in its original case. IP54 means it's dust-protected and splash-proof, so it's fine for outdoor use in light rain or dusty conditions, but don't submerge it.
