We've been moving these wrenches for about three years now and what you'll notice immidiately is that aluminum-titanium alloy body makes them maybe 15-20% lighter than the steel ones you're probably used to handling — operator fatigue drops noticeably on those long shift jobs in shipbuilding or wind tower assembly. It's not for overhead crane work though, the rough tooth design grabs fine but it's bulkier than a ratchet style, so just factor that in.
Basically, you're looking at tooling for tightening flange bolts on pipelines or structural steel where you need consistent torque across a large assembly, think 30-64mm bolts and nuts form 46-95mm. The 1094 to 10941 Nm range covers most heavy bolting work we see, though we keep a separate series for that sub-1000 Nm stuff because this one runs best at the higher end of its curve.
Accuracy sits at plus or minus 3% which we validate with an in-house hydraulic test rig that reads to a tighter tolerance than most labs, and we ship each unit with a calibration cert traceable to way higher standard. Working pressrue is 170 MPa (pretty aggressive on the seals, we usually replace the O-rings at around the 10-month mark) but the anti-corrosion coating holds up fine even when they sit on a damp truck bed overnight.
1 year defects but we've only had maybe 4 returns in the last 150 units sold, mostly shipping damage on the handle trigger assembly. OEM is availble (we do private labeling under our SA-series numbering) but lead times shift — standard stock ships in 3-5 days, custom colors take 3 weeks or so. Payment is typical T/T or L/C at sight, we confirm wire receipt before dispatch.
COA and CE paperwork are standard in crate, we also attach the ISO9001 file number so your qualiy team can just call up the facility audit records. The rough tooth design is actually more about reducing slip on wet or greasy hex points than improving bite strength anyway, it's a practical feature for field crews. Shipping goes FOB Qingdao or CIF if you prefer.
The torque range is 1094 to 10941 Nm with ±3% accuracy. The rough tooth structure is designed for better grip on bolts and doesn't reduce precision—it actually helps maintain consistent torque application on worn or slippery fasteners.
Yes, we offer OEM service and can match custom colors or branding. Standard lead time is around 20-30 days, depending on the order volume and customization complexity.
It's CE and ISO9001 certified. We can supply test reports for torque accuracy and material specs upon request—just ask your sales contact.
Our standard MOQ is 1 unit for stock models, so you can order a single wrench for testing. For OEM versions, MOQ may be higher—typically 10-20 pieces.
Store it in a dry, clean environment to protect the coating. The anti-corrosion surface treatment handles hydraulic oil and common workshop fluids well, but wiping it down after use extends its life.
