Precision Torque Wrench

1、 Core parameter analysis
Model: SN-2025
Drive specifications: 1/4 "square head (compatible with small socket sizes, covering common screws M3~M8)
Torque range: 5-25N · m (synchronously labeled with metric derived units of 45-255cm · kg, convenient for traditional unit users to refer to, 1cm · kg ≈ 0.098N · m)
Net weight: 0.9kg (lightweight design, no fatigue after long-term operation)
Packaging size: 32 × 10 × 7 cm (compact storage box, easily compatible with toolkits/drawers)
2、 Product Core Value
1. Precise control of small torque
Specially designed for precision assembly scenarios, torque adjustment accuracy meets industrial grade standards:

Low starting point (5N · m): Avoid slipping micro screws (such as phone motherboards and lens mount);
Wide coverage (5-25N · m): Suitable for mainstream small torque requirements such as bicycle handlebars (10-15N · m) and power tool accessories (8-18N · m).
2. Scene penetration power driven by 1/4 "
1/4 "square head compatible with all series of small-sized sockets, perfectly solving the pain point of" large wrench easily slipping/over twisting small screws ", covering:

3C digital: disassembly and assembly of chips/screws for mobile phones, laptops, and drones;
Fine tuning of bicycles: torque specifications for flower drum, disc brake, and gearbox;
Precision instruments: assembly and maintenance of lenses, medical devices, and models;
Safe fastening of household small items: children's furniture, toy hardware.
3. Bidirectional ratchet+lightweight design
Ratchet head: bidirectional fast reversing, smooth lever operation, no need to flip wrench for disassembly, efficiency increased by 30%+; The bite teeth are fine and precise, with no idle torque transmission, avoiding "false tightening".
Handle: Alloy shaft+anti slip rolled flower grip, weighing only 0.9kg, balancing strength and maneuverability, easy to grip with one hand.
3、 Design and Material Details
Adjustment system: metal scale ring+locking knob, laser etched scale (clear and wear-resistant), locked to prevent misoperation after adjustment, ensuring stable torque output.
Storage plan: The hard plastic box has built-in grooves that tightly fit the wrench, isolating dust/collisions, making it easy to classify tools and carry them out.
Material certification: The shaft is made of Cr-V alloy steel (chrome vanadium steel), which has strong torsional resistance, excellent rust prevention performance, and low precision degradation rate after long-term use.
4、 Typical application scenarios
✅ 3C digital repair: mobile phone motherboard screws (1-5N · m), laptop hard drives (3-8N · m), drone motor mounts (8-15N · m).
✅ Bicycle maintenance: Install the vertical screw (10-15N · m), disc brake clamp (8-12N · m), and flower drum shaft (15-20N · m).
✅ Precision assembly: lens mount (3-6N · m), medical device components (5-12N · m), model car/aircraft fastening.
✅ Home scene: Children's furniture screws (5-10N · m), power tool accessories (8-18N · m), toy hardware.
