Key Features & Specifications
- Bent Handle Design – Allows 60° offset access for working in confined or offset positions; ideal for flange bolts and recessed fasteners.
- Striking Cap – Integrated striking surface on the back of the bent end; safe to strike with a steel hammer for breaking stubborn torque.
- Heat Treated Core – Through-hardened to 50-55 HRC for wear resistance; drawn temper ensures shock absorption without brittleness.
- Full Size Range – Available individually from 6mm to 36mm (metric) or as a complete set. Each wrench is marked with clear size engraving.
- Material – Made from Chrome Vanadium Steel (Cr-V) with excellent strength-to-weight ratio; optional phosphate or black oxide coating for corrosion resistance.
- Precision Manufacturing – CNC machined and inspected to DIN 895 / ISO 2936 tolerance standards (upon request).

Why Choose Our Bent Handle Striking Hex Wrench?
- Enhanced Torque Transfer – The bent handle acts as a lever, multiplying applied force; the striking face allows additional hammer blows for high-torque removal of seized fasteners.
- Ergonomic Advantage – Reduced wrist strain compared to straight hex keys; better grip angle reduces fatigue during repetitive use.
- Durable Heat Treatment – 50-55 HRC ensures the tool resists deformation while maintaining the toughness needed to absorb impact without chipping or cracking.
- Versatile Applications – Ideal for automotive suspension work, heavy machinery assembly, pipe flange bolting, and any situation where a standard L-key cannot access the fastener.
- Customizable Options – We offer size marking in both raised and engraved styles, different packaging (blister cards, plastic boxes, or industrial bundles), and surface finishes like black oxide or phosphate.

Frequently Asked Questions (FAQ)
Q1: Are the wrenches sold as a set or individually?
A: Both options are available. We offer complete sets from 6-36mm in a convenient storage case, as well as individual sizes for replacements or custom selection.
Q2: Can I use a hammer directly on the striking surface?
A: Yes, the bent end is specifically designed with a flat striking face. We recommend using a steel hammer (not softer than the tool) to avoid damage. For repeated heavy blows, a protective copper hammer is suggested for minimal deformation.
Q3: What is the hardness range and how is it achieved?
A: The wrenches are heat-treated to a consistent 50-55 HRC via a controlled oil-quench and tempering process. This provides an optimal balance of wear resistance and impact toughness.
Q4: Do you offer surface coating for rust prevention?
A: Yes, we offer black oxide and phosphate coatings as standard optional finishes. These coatings provide corrosion resistance and reduce glare. Custom coatings (e.g., zinc plating, DLC) are available on request.
Q5: What materials are used?
A: Our standard material is Chrome Vanadium Steel (Cr-V) with good strength and durability. We can also manufacture from S2 steel or other alloys for specialized applications.
Q6: Can I get custom size markings or branding on the tool?
A: Absolutely. We provide OEM/ODM services including laser engraving, etching, or stamping your logo and size marks. Minimum order quantities may apply for custom branding.
Q7: What is the typical lead time for bulk orders?
A: For standard sizes and finishes, lead time is approximately 15-25 days after deposit. Custom orders may require 30-45 days depending on complexity and quantity.
Q8: Do you have certifications for quality management?
A: While we do not list specific certifications here, our manufacturing process follows ISO 9001 principles. We can provide test reports and inspection records upon request to ensure product consistency.
