- High-strength 45# steel – The material is heat-treated to achieve optimal hardness and toughness, resisting deformation under heavy torque.
- Precision hexagonal opening – The 6-point design provides a full contact surface on the fastener, minimizing slippage and extending the life of both wrench and nut.
- Ergonomic straight handle – The 275 mm length offers sufficient leverage for most applications, while the straight shape allows for easy access in confined spaces.
- Rust-resistant finish – The black oxide coating protects against corrosion and provides a non-glare surface for better visibility in work areas.
- Single box-end configuration – Ideal for jobs where a box-end wrench is preferred over an open-end for maximum grip and torque transmission.
- Customizable options – We can supply different sizes, lengths, finishes, and packaging to meet your specific requirements. Contact us for a quote.
Application & Benefits
This wrench is primarily used in automotive repair (e.g., suspension, brake systems), industrial machinery maintenance (e.g., tightening bolts on conveyors, presses), and construction equipment. The 32 mm size is common for large fasteners on trucks, agricultural machinery, and heavy equipment. By using our single box-end wrench, you can apply higher torque without damaging the fastener head, thanks to the six-point engagement. The straight handle allows for better control and reduces hand fatigue during repetitive tasks. Compared to combination wrenches, the dedicated box-end design offers a more secure fit, especially when dealing with worn or rounded nuts.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a box-end wrench and an open-end wrench?
A: A box-end wrench completely surrounds the fastener head, providing a stronger grip and reducing the risk of slipping. It is ideal for applying high torque, while an open-end wrench is easier to slide onto a fastener but may slip under heavy load. -
Q: Is this wrench suitable for use with impact tools?
A: This is a manual wrench designed for hand use. It is not recommended for use with impact wrenches as the 45# steel may not withstand the sudden high torque of impact tools. For impact applications, we recommend our impact socket line. -
Q: Can you provide other sizes or lengths?
A: Yes, we offer a wide range of sizes from 8 mm to 50 mm and custom lengths. Please contact us with your requirements for a quotation. -
Q: What is the hardness of this wrench?
A: After heat treatment, the hardness is typically between HRC 38-42, providing a balance of strength and toughness to prevent breakage. -
Q: What surface treatments are available?
A: Standard finish is black oxide. We can also apply phosphate, chrome plating, or other coatings upon request. Please specify your needs. -
Q: Do you offer OEM/ODM services?
A: Absolutely. We can manufacture wrenches with your brand logo, custom packaging, and specific design requirements. Minimum order quantity may apply. -
Q: How do you ensure product quality?
A: We have a dedicated quality control team that inspects dimensions, hardness, and surface finish before shipment. Samples can be provided for testing upon request. -
Q: What is the typical lead time?
A: For standard stock items, lead time is 7-15 days. For custom orders, it depends on quantity and specifications, typically 20-30 days.
