Hangzhou Xinabo Intelligent Electromechanical Technology Co., Ltd manufactures lithium-ion brushless wrenches for bolted connections in pipeline installation, fire protection engineering, steel structure erection and equipment maintenance. As an Engineering Construction Pipeline Connection Solutions manufacturer, we build this range around the same site conditions our threading and pipe fabrication equipment serves: crews working overhead, in trenches and in plant rooms where a corded tool and an air hose are impractical.
Five models cover the range, from a 16 V compact angle ratchet at 70 N·m to a 21 V impact wrench at 850 N·m. Each one uses a brushless motor, a lithium-ion battery platform and an impact or ratchet mechanism matched to the fastener class it is intended to serve.
- Brushless motors for longer runtime and fewer service interventions than brushed equivalents
- Variable speed or multi-step torque settings for controlled run-down
- One-touch forward/reverse switching for repetitive bolting sequences
- Overload, under-voltage and overheat protection on the industrial models
- LED work lights for risers, plant rooms and night shifts
- Anti-slip, vibration-damping handles for extended overhead work

Where Each Wrench Type Fits
21 V impact wrenches — pipe supports, flanges and steelwork
The XJ.580, XJ.533 and XJ.523 share the 21 V platform and cover the bolting that follows pipe fabrication: hanger and support brackets, flange sets, riser clamps and structural connections. Torque output and impact mechanism differ so that a crew can hold one battery platform across a site while matching the tool to the joint.
- XJ.580 at 850 N·m for high-strength bolting where the highest available torque is required
- XJ.533 at 550 N·m as the general-purpose site tool for mixed fastener sizes
- XJ.523 at 350 N·m with a heavy-duty impact mechanism for rusted, painted or seized bolts
- XJ.570 at 750 N·m with a 1/2" square drive for light industrial and maintenance work
16 V angle ratchet wrench — confined and small-bolt work
The XJ.592 reaches joints a straight impact wrench cannot address. Its 360° rotating ratchet head and compact body suit valve trains, pump skids, cable tray and small-bolt assembly where swing radius is limited. At 70 N·m it is a fastening and removal tool for small fasteners, not a substitute for a high-torque impact wrench.
Configuration Options and Battery Platform
We configure each order around the joint schedule and the way the crew actually works, rather than shipping a fixed kit. The cordless power tool platform is shared across our Cordless Power Tools range, so batteries and chargers can be pooled across wrenches, drills, hammers and cutters on the same project.
- Battery quantity per tool, sized to the number of joints per shift and the charging rotation available
- Charger configuration matched to the site supply voltage and the charging point location
- Drive size and socket or adapter set selected against the fastener head
- Backpack battery supply for extended overhead or high-volume work, using our Backpack Lithium Battery Pack
- Tool mix per crew, combining impact wrenches with an angle ratchet for restricted joints
Controls, Protection and Operator Safety
Control logic is what separates a production bolting tool from a general-purpose driver. Speed and torque settings are stepped so an operator can select a band for the fastener in hand, and the protection layer is designed to stop the tool before the joint or the motor is damaged.
- XJ.570: intelligent power-off protection that stops automatically once the bolt is fully tightened, preventing over-torquing
- XJ.580: triple protection against overload, under-voltage and overheat
- XJ.523: intelligent control monitoring operation status with fourfold safety protection
- XJ.533: built-in overload protection with power-off memory
- XJ.592: built-in overload protection with LED work light
- Anti-slip, vibration-damping handles and one-touch forward/reverse switching across the range
Quality Control and Acceptance
Hangzhou Xinabo holds 30 patents and the National High-Tech Enterprise title, and our engineering work on pipe connection equipment runs through nine generations of intelligent threading machines. The same development and inspection discipline applies to the cordless range: motor and mechanism assembly, switch and control function, battery and charger compatibility, and a run test before packing.
Conformity documentation covering the Machinery Directive and the Electromagnetic Compatibility Directive is held for our equipment. Where a project requires a specific acceptance record, we agree the inspection points and the documentation set before production rather than after delivery.
Information We Use to Configure Your Solution
A wrench proposal is only useful if it matches the joint. These are the inputs we work from when selecting models, batteries and accessories for a project.
| Project input |
What we confirm with it |
| Fastener size, thread and property class |
Drive size, socket range and the torque setting band to use |
| Target torque and tightening method |
Model selection, speed setting and whether torque-limited run-down is required |
| Bolt condition — new, galvanized, painted, rusted or seized |
Impact mechanism class and breakaway capability needed |
| Access and clearance around the joint |
Straight impact wrench or 360° angle ratchet, and tool mix per crew |
| Joints per shift and shift length |
Battery capacity, number of packs and charger rotation |
| Site supply voltage and charging location |
Charger configuration matched to the available supply |
| Working environment and connection standard |
Lighting, grip and accessory selection, plus the documentation and acceptance criteria agreed before delivery |
Maintenance, Spare Parts and Documentation
Brushless construction removes the carbon brush replacement cycle that dominates brushed tool maintenance, leaving the impact mechanism, switch assembly, battery and charger as the service points. We supply spare parts for our products and provide technical training and demonstrations for partner teams, so a contractor can keep a fleet running without returning tools for routine work.
Delivery scope is confirmed per order: tool, battery packs, charger and the drive or socket accessories selected for the application, together with operating documentation. For projects that combine bolting with pipe preparation, the wrench range is specified alongside our Pipe Fabrication & Installation Equipment so that cutting, threading and fastening are planned as one sequence.
Frequently Asked Questions
Which model suits flange and pipe support bolting on a fire protection project?
For high-strength bolting on supports and steelwork, the XJ.580 at 850 N·m with three adjustable settings covers most mid-duty work. The XJ.533 at 550 N·m is the general-purpose choice for mixed site fastening, and the XJ.523 at 350 N·m with its heavy-duty impact mechanism is used where bolts are rusted or seized. We confirm the model against your fastener size, target torque and access conditions.
Do the wrenches stop when the bolt is fully tightened?
The XJ.570 has intelligent power-off protection that stops the tool automatically once the bolt is fully tightened, which prevents over-torquing. The XJ.580 carries overload, under-voltage and overheat protection, the XJ.523 uses an intelligent control system with fourfold safety protection, and the XJ.533 has built-in overload protection with power-off memory.
Can a crew run the wrenches from a backpack battery?
Yes. Our backpack lithium battery pack is specified for extended overhead work and high-volume bolting where belt-mounted packs would be changed too often. We size the pack and the number of spare batteries from your joints-per-shift figure.
What is included in a delivery?
Each order is packed to the configuration agreed at quotation: the tool, battery packs, charger and the drive or socket accessories selected for the application, with operating documentation. Packaging and delivery scope are stated on the order confirmation so that receiving inspection matches what was specified.
How do you support maintenance and spare parts after handover?
We supply spare parts for our products and provide technical training and demonstrations for partner teams. Because the range is brushless, routine service focuses on the impact mechanism, switch assembly, battery and charger rather than motor brush replacement.
What do you need from us to prepare a quotation?
Send the fastener sizes and property classes, target torque, bolt condition, access restrictions, joints per shift, site supply voltage and the connection standard being worked to. With those inputs we return a model selection, battery and charger configuration, accessory list and the documentation set for the project.
