With an annual export value exceeding US$100 million and a global footprint spanning North America, South America, Europe, Asia, Africa, and Oceania, we deliver reliability and performance that professionals count on. This bent hammering spanner combines high-strength 45# carbon steel with an ergonomic bent design, providing both the leverage and the impact resistance needed for tasks where ordinary wrenches fail. Whether in oil fields, shipyards, or construction sites, this tool is built to withstand repeated hammer blows while maintaining precise engagement with fasteners.
Key Features & Benefits
- Premium 45# Carbon Steel Construction – Offers exceptional toughness and durability, resisting deformation under heavy impact.
- Bent Handle Design – Provides optimal leverage and clearance, allowing the wrench to be struck with a hammer directly on the reinforced striking face without damaging the tool.
- Open End with Precise Jaw Dimensions – Ensures a tight fit on hex nuts and bolts, reducing slippage and damage to fasteners.
- Heat Treated for Hardness – The entire wrench undergoes controlled heat treatment to achieve a balance of strength and toughness, meeting heavy-duty work cycles.
- Available in Multiple Sizes – From 27mm to 80mm (and custom sizes on request), covering a wide range of fastener dimensions.
- Corrosion Resistant Finish – Options include black oxide or phosphate coating for extended service life in harsh environments.
- Customizable – OEM/ODM services available for branding, packaging, and specialized dimensions.

Frequently Asked Questions (FAQ)
Q: What makes this wrench different from a standard open end wrench?
A: This bent striking wrench is designed specifically for heavy-duty impact. It has a thicker reinforced striking face at the end of the handle, allowing it to be struck with a hammer to generate high torque. The bent shape provides better access in tight spaces and reduces the risk of hand injury during striking.
Q: Can the wrench be used for tightening as well as loosening?
A: Yes, it can be used for both tightening and loosening. The open end allows it to engage hex fasteners from the side, and hammer blows can be applied in either direction. However, for critical torque applications, we recommend using a torque wrench for final tightening.
Q: What sizes are available?
A: Standard sizes range from 27mm to 80mm. We also offer custom sizes according to your specifications. Please contact our sales team for a full size chart and availability.
Q: Is the tool heat treated?
A: Yes, each wrench undergoes a controlled heat treatment process to achieve the optimal balance of hardness and toughness. This ensures the tool can withstand repeated striking without cracking or deforming.
Q: Can I get my company logo printed on the wrench?
A: Absolutely. We offer OEM/ODM services, including custom branding, packaging, and even handle modifications. Minimum order quantities may apply.
Q: How is the surface finish? Does it resist rust?
A: Standard finishes include black oxide and phosphate coating, both of which provide good corrosion resistance. For extremely corrosive environments, we can apply additional coatings upon request. Proper maintenance (keeping dry and lightly oiled) will extend the tool's life.
Q: What is the typical lead time?
A: Lead time depends on the quantity and size. Small orders (under 100 pieces) are usually shipped within 15-20 days. Larger orders or custom sizes may take 30-45 days. Please confirm with our sales team for accurate delivery schedule.
Q: Do you provide a quality guarantee?
A: Yes, we stand behind the quality of our products. If you receive any defective tool, we will replace it or issue a refund. Our long-standing partnerships with global clients testify to our commitment to quality.
