Frequently Asked Questions
Q1: What makes the convex striking face better than a flat face?
A1: The convex shape concentrates the striking force into the center of the wrench, reducing the risk of edge chipping or mushrooming. This extends the tool’s lifespan and improves safety during repeated impacts.
Q2: Is the anti‑corrosion coating suitable for outdoor use?
A2: Yes. Our phosphate or black oxide coating is designed to resist rust and corrosion, even in humid, salty, or chemically‑exposed environments. It has passed 120‑hour neutral salt spray testing.
Q3: Does this wrench come with any certifications?
A3: The tool is manufactured to meet common international standards (e.g., DIN 7448). Specific certification documents (such as material test reports) are available upon request.
Q4: Can I order a different length or custom logo?
A4: Absolutely. We support OEM/ODM services. Minimum order quantities may apply – please contact us with your requirements.
Q5: What is the torque capacity when struck with a sledgehammer?
A5: The wrench can withstand striking loads exceeding 1500 N·m without permanent deformation. Actual torque delivered depends on the hammer used and striking technique.
Q6: How do I choose between a convex and a conventional striking wrench?
A6: If you frequently work with large fasteners or need to deliver heavy impacts, the convex design reduces stress on the wrench and fastener, making it a superior choice. For lighter tasks, a standard flat‑face wrench may suffice.
Q7: What is the packaging method?
A7: Standard packaging is individual polybag or blister pack, with options for custom boxes or foam inserts for tool kits. Bulk orders can be packed in cartons or wooden crates according to your preference.
Q8: What is your typical lead time?
A8: For standard 36mm wrenches, lead time is 15–25 days after order confirmation. Larger quantities may require 30–45 days. We can expedite upon request.
