Welcome to Cangzhou Dean Safety & Special Tools Co., Ltd. — a dedicated manufacturer with over 20 years of experience in producing premium industrial tools. Since 2001, we have been serving global clients with annual exports exceeding US$100 million. Our Industrial Grade Bent Striking Open End Wrench (45# Steel) is designed for demanding environments where standard wrenches fail. This impact open end spanner integrates a unique bent head and a striking face, allowing controlled hammer blows for loosening or tightening stubborn fasteners. Crafted from high-quality 45# carbon steel and heat-treated for superior strength, it delivers exceptional torque transmission and long service life. Whether you work in heavy machinery maintenance, oil field assembly, or construction rigging, this tool brings efficiency and safety to every job.
Key Design & Performance Features
- 45# Carbon Steel Construction: The core material ensures high tensile strength and wear resistance, giving the wrench a robust structure that withstands heavy-impact usage without deformation.
- Bent Head Design: The angled opening (typically 15° or 30°) allows better access to recessed or confined fasteners, reducing the need for additional extension tools.
- Integrated Striking Face: A specially designed flat striking surface on the handle end permits safe hammer blows, enabling increased torque while protecting the user’s hand.
- Precision Open End: The jaw is accurately machined to fit standard nut/bolt sizes, minimizing slippage and rounding of corners. Each wrench is tested for dimensional consistency.
- Heat Treatment & Hardness Options: Standard hardness around 38–45 HRC; customized treatments available for specific applications (e.g., extra-impact, corrosion resistance).
- Black Oxide or Phosphate Finish: Provides anti-rust protection and a non-glare surface, suitable for workshop and field use.
- Ergonomic Handle: The handle length and shape are optimized for leverage, reducing user fatigue during prolonged tasks.

- Versatile Fit: Available in metric and imperial sizes, suitable for global OEM and aftermarket needs.
- Customization: We can tailor the bend angle, hardness, finish, and even laser-etch your logo or part number — perfect for private labeling.

Frequently Asked Questions
Q1: What is the main difference between a standard open end wrench and a bent striking wrench?
A: The bent striking wrench features an angled head (typically 15–30°) and a built-in striking face at the handle end. This design allows you to apply impact force with a hammer to loosen or tighten stubborn fasteners, and the bend gives better access in confined spaces.
Q2: Is the 45# steel strong enough for heavy industrial use?
A: Yes, 45# (C45) carbon steel offers an excellent balance of strength and ductility. After heat treatment, it achieves hardness levels suitable for impact applications. For extreme conditions, we can supply higher hardness versions or alternate materials upon request.
Q3: Can I get the wrench in different surface finishes?
A: Absolutely. Standard finishes include black oxide and phosphate. We also offer zinc plating, chrome plating (for non-impact use), or plain oiled finish. Please specify your anti-corrosion or aesthetic requirement.
Q4: Do you provide custom sizes or special bend angles?
A: Yes. We can produce any size from 6mm to 100mm (or inch equivalents) and bend angles from 10° to 45°. Just send your drawing or size list, and we will offer a tailored solution.
Q5: Is it safe to hammer on the wrench even with the striking face?
A: Yes, the striking face is specifically designed and reinforced to absorb hammer blows. However, always use a steel hammer or a soft-face hammer as recommended. Avoid using an oversized hammer beyond the wrench’s rated capacity.
Q6: What packaging options are available for bulk orders?
A: You can choose individual blister packs, polybags, full sets in tool rolls, or bulk loose packing. We also offer private labeling with your brand logo and barcode if required.
Q7: How do I place an inquiry or request a sample?
A: Contact us through the B2B platform messaging system or email our sales team directly. Provide the desired size, quantity, and any special requirements. We typically respond within 24 hours with a quotation and lead time.
Q8: Can I get a smaller starting order for testing before committing to large volume?
A: Yes, we welcome trial orders. Minimum order quantity varies by size, but we are flexible to help you evaluate the product quality. Our standard sample is available with reasonable cost and can be deducted from future bulk orders.
