Key Features & Technical Specifications
- Premium Material: Constructed from high-grade Chrome Vanadium (Cr-V) steel, ensuring exceptional durability, corrosion resistance, and long service life. The alloy composition provides superior strength-to-weight ratio.
- Precision Double Box End: Both ends feature a 12-point box design that engages with fastener flats for maximum torque transmission while minimizing rounding of hex bolts/nuts. Ideal for tight spaces where high leverage is needed.
- Metric Sizing (6mm – 24mm): Available in a wide range of metric sizes to suit various precision assembly applications. Each wrench is calibrated to exacting tolerances (±0.1mm) for a secure fit.
- Straight Handle Design: The straight handle offers a balanced grip and allows for easy rotation in confined areas. Its polished chrome finish not only looks professional but also resists rust and simplifies cleaning.
- Heat Treated Hardness HRC 45-50: Undergoes precise heat treatment process to achieve optimal hardness without brittleness, ensuring the tool withstands repeated high-torque usage.
- Anti-Slip Surface: The handle is designed with a slight knurl or texture (optional upon request) to improve grip even with oily hands.
- Lightweight yet Strong: Average weight per wrench ranges from 50g to 300g depending on size, reducing operator fatigue during extended use.

Why Choose This Wrench for Precision Assembly?
In precision mechanical assembly—such as in automotive engines, aerospace components, or electronic equipment—every millisecond counts and every fastening must be accurate. Our double box end wrench offers consistent torque application without the risk of slipping. The 12-point head provides 30° increments of rotation, allowing you to work in tight spaces without repositioning the tool. Compared to open-end wrenches, the box end completely envelops the fastener for greater safety and less fastener damage.
The straight handle design is especially beneficial for assembly lines or bench work where a vertical approach is common. It reduces wrist strain and offers better control when aligning the wrench onto fasteners. Moreover, the Cr-V steel construction ensures that even after thousands of cycles, the tool maintains its dimensional accuracy—critical for maintaining consistent torque values.

Frequently Asked Questions (FAQ)
Q1: What is the advantage of a double box end wrench over a combination wrench?
A: A double box end wrench has both ends with a box design, providing maximum grip and torque on fasteners without the risk of rounding. It is ideal for assembly tasks where high torque and precision are needed, especially in confined spaces.
Q2: Are these wrenches available in both metric and imperial sizes?
A: This specific product line is metric (6mm to 24mm). Imperial sizes (SAE) can be made available upon request as a custom order. Please contact our sales team for details.
Q3: How do I choose the correct size for my fasteners?
A: Measure the width across flats of your bolt or nut. The wrench size should match exactly. If you are working on standard metric hardware, common sizes are 10, 12, 13, 14, 17, and 19 mm.
Q4: Is the chrome plating durable?
A: Yes, our chrome plating undergoes a multi-layer process (nickel undercoat + chrome topcoat) that exceeds 48 hours of salt spray resistance. It is highly resistant to corrosion and wear.
Q5: Can I get custom laser engraving or branding on the wrench?
A: Absolutely. We offer custom laser engraving or etching of your company logo, part numbers, or other markings. Minimum order quantities may apply; consult our team for options.
Q6: Do you provide a calibration certificate for the wrench size accuracy?
A: Standard production does not include a certificate, but we can provide an inspection report or calibration certificate upon request for an additional fee. Our internal tolerances are ±0.1mm on the jaw opening.
Q7: What is the typical lead time for large orders?
A: For standard sizes, lead time is 20-30 days after order confirmation. For custom sizes or branding, it may extend to 35-45 days. Expedited shipping is available.
Q8: Can this wrench be used for tightening or only loosening?
A: It is suitable for both tightening and loosening. However, for precision assembly, we recommend using a torque wrench to set final torque values. This wrench provides excellent leverage for initial fastening or breakaway.
