- Hammering Face: Large, flat striking surface on the opposite end of the open jaw, designed for use with a heavy-duty hammer.
- Precision Jaw Opening: CNC machined to ensure tight tolerance and perfect grip on hex fasteners.
- Ergonomic Handle: Contoured with anti-slip knurling for secure grip even in oily or wet conditions.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a standard open end wrench and a striking wrench?
A: A striking wrench has a reinforced, flat striking surface on the handle end that allows you to hit it with a hammer to apply additional torque. Standard wrenches are not designed to withstand such impact loads and can break or deform. -
Q: Can this wrench be used with a power impact tool?
A: No, this product is specifically designed for manual hammering with a sledgehammer or maul. It is not intended for use with power tools, as the repeated shock can damage the tool or cause injury. -
Q: Are metric sizes available?
A: Yes, we offer both imperial (inch) and metric sizes. Common metric sizes range from 30mm to 80mm, and custom sizes are available upon request. -
Q: What type of heat treatment does the wrench undergo?
A: The wrench is quenched and tempered to achieve a hardness of 38-45 HRC, which provides an excellent balance of toughness and wear resistance. -
Q: Do you provide OEM service with custom branding?
A: Absolutely. We can laser engrave your company logo, part numbers, or other markings on the wrench handle. Minimum order quantities apply for custom branding. -
Q: What is the lead time for standard sizes?
A: For standard sizes, typical lead time is 15-25 days after order confirmation, depending on quantity. Custom orders may require additional time. -
Q: Is the wrench surface coated to prevent rust?
A: Yes, the standard finish is black oxide, which provides moderate corrosion resistance. Optional phosphate coating or zinc plating is also available. -
Q: What is the warranty policy?
A: We offer a standard one-year warranty against manufacturing defects. Our tools are built to last, but if you experience any issues, please contact our customer service team for assistance.
