Can this wrench be used on metric and imperial bolts?

Yes, the 71 mm opening corresponds to M48 metric thread and W 1-7/8 Whitworth thread, making it suitable for both systems.

Is the wrench suitable for marine environments?

Absolutely. The alloy steel construction with hardened finish provides excellent resistance to corrosion and wear, ideal for marine applications.

What is the overall length of the wrench?

The overall length is 552 mm, offering substantial leverage for loosening or tightening large fasteners.
