Set Of 6 Large Open-end Wrenches, 27-41mm

1. Quick overview of basic parameters
Set specification: 6 pieces, covering 27/30/32/34/36/41mm (precisely tackling large-sized bolts for heavy machinery, heavy-duty trucks, and industrial equipment, filling the gap in conventional sets)
Storage design: Roll-up wear-resistant canvas bag (unfolded: 42×48cm, folded: 49×12×5cm), with independent card slot + orange edging, allowing even large wrenches to be stored in a single roll, saving space in tool cabinets.
Weight: Total weight 4.7kg (individual weight 0.390–1.346kg, featuring a large-sized long handle design that balances "high torque" and "maneuverability")
II. Core Value: The "Game-changer" in Heavy-duty Operations
1. Large-sized "full-scene coverage"
Addressing the pain points of "conventional wrenches not working and sets lacking specifications", with precise coverage:

Heavy-duty truck maintenance: wheel hub bolts (30-36mm), half-shaft screws (32-34mm);
Construction machinery: excavator track bolts (36-41mm), loader hydraulic pipe fittings (27-32mm);
Industrial installation: large motor base (30-36mm), boiler flange bolt (34-41mm).
2. Heavy-duty design, "durable and robust"
Long-handled mechanical advantage: With a wrench of up to 41mm and a long handle of 451mm, the lever arm is enlarged by 30%+, making high-torque operations more effortless (compared to short handles, the same torque requires 1/3 less force);
Material and craftsmanship: Chrome-vanadium steel (Cr-V) forged + quenched, with a tensile strength exceeding 800MPa, and it is not easily deformed even during hammering operations (with a rubber hammer);
Opening accuracy: Laser cutting for openings with a tolerance of ≤0.05mm, ensuring tight engagement with large-sized nuts and eliminating "slip and breakage".
3. Rolling storage "turning complexity into simplicity"
Even a large wrench can be "portable": with a folded size of 49×12×5cm, it can easily fit into the side pocket of a tool cart or the toolbox of a heavy-duty truck;
Visualized placement: Orange edging + clear specification labeling, ensuring "one insertion, one stability" during storage, preventing large wrenches from bumping and damaging inside the box.
III. Design Details & Scenario Adaptation
1. Exclusive design for heavy-duty operations
Thickened shaft: The large-sized wrench shaft is 8-12mm thick, with a 50% increase in torsional resistance, suitable for impact operations (such as loosening bolts by striking);
Anti-slip chamfering: The edges of the handle are chamfered, making it easier to grip with greasy hands or when operating with gloves, thus preventing slipping and falling off.
2. Typical application scenarios
✅ Heavy-duty truck/construction machinery maintenance: wheel hub disassembly (30-36mm), suspension system fastening (27-32mm), track screw (36-41mm);
✅ Industrial equipment installation: flange bolts (34-41mm) for large compressors and generators, and heavy-duty bracket fixation (27-32mm);
✅ Mining/Infrastructure Machinery: Maintenance of key components of crushers and cranes (30-41mm).
IV. Comparative Advantages: Why Choose It?
Comparison dimension: Ordinary wrench set (≤24mm) vs. Solude large-sized set
Specification coverage: Stop small/medium specifications, 27-41mm, specializing in heavy-duty bolts
Torque capacity: Short handle requires more effort and is prone to slipping; long handle saves effort + Cr-V material, resistant to torsion and impact
Storage method: Boxed items take up space; roll-type cloth bags allow for "light storage" even with large wrenches
