At Cangzhou Dean Safety&Special Tools Co., Ltd, we take pride in delivering high-performance industrial tools engineered for the toughest fastening tasks. Our Bent Striking Hex Wrench Quenched Tempered 65Mn Steel High Toughness for Tight Bolts is specifically designed to provide maximum torque transfer and durability when dealing with stubborn, over-tightened, or corroded bolts. With over two decades of manufacturing expertise since 2001, our factory in Cangzhou, Hebei, ensures every wrench meets rigorous quality standards, making it a reliable choice for professionals worldwide.
This striking wrench features a unique bent geometry that allows for optimal access to recessed bolts and confined spaces. Crafted from premium 65Mn spring steel, the wrench undergoes a precise quenching and tempering process to achieve an exceptional balance of hardness and toughness. The result is a tool that withstands heavy impact without cracking or deforming, ensuring long service life even under repeated high-stress usage. Ideal for industries such as automotive repair, heavy machinery maintenance, construction, and oil field operations, this wrench helps technicians work efficiently and safely.
Key Features & Technical Specifications
- Material Excellence: 65Mn steel offers superior elasticity and wear resistance, ensuring the wrench maintains its shape under high torque.
- Optimal Heat Treatment: Quenched and tempered to achieve a hardness range of HRC 40–50 (adjustable per request), providing a perfect combination of strength and impact toughness.
- Bent Design: The offset angle allows for better leverage and clearance, making it easier to strike with a hammer without damaging the bolt head or surrounding components.
- High Toughness: Engineered for repeated striking, the wrench resists chipping and fracture, reducing the risk of tool failure during critical operations.
- Versatile Application: Suitable for both tightening and loosening hex bolts, especially those in tight spaces where standard wrenches cannot reach.
- Customizable Options: Available in various sizes (from 8mm to 55mm or equivalent inch sizes) and surface finishes (black oxide, phosphating, or color coating) to meet specific job requirements.

Frequently Asked Questions
Q1: What makes this wrench different from a regular hex wrench?
A: This wrench is bent to provide better access in restricted spaces and is specifically designed for striking with a hammer. The 65Mn steel with quenching and tempering gives it superior toughness to withstand repeated impact without breaking.
Q2: Can I use this wrench for both tightening and loosening?
A: Yes, it works effectively for both operations. The hex head fits standard bolts and nuts, and the striking face allows you to apply additional force when needed.
Q3: What sizes are available?
A: We offer a wide range of sizes from 8mm to 55mm (metric) and equivalent inch sizes. Custom sizes are available upon request for large or special orders.
Q4: Is the wrench coated to prevent rust?
A: Yes, the standard finish is black oxide, which provides corrosion resistance. We also offer phosphate coating or other finishes as needed.
Q5: How do I choose the right size for my bolts?
A: Measure the across-flats dimension of the bolt head. Our wrench sizes correspond directly to this measurement. If unsure, please contact us for guidance.
Q6: Can I get a sample before placing a bulk order?
A: Absolutely. We provide free samples for quality evaluation. You only need to cover the shipping cost. We are confident you will be impressed by the performance.
