The Slogging Spanner 65mm Ring End CRV is a heavy-duty wrench designed for use in tough, high-torque applications. Featuring a 65mm ring end, this spanner is typically used for loosening or tightening large fasteners, often in mechanical, industrial, or construction settings. The "CRV" refers to Chrome Vanadium steel, a durable and corrosion-resistant material known for its strength and longevity, making the spanner suitable for demanding tasks. The design allows for the application of a striking force (slogging) with a hammer, making it ideal for stubborn or rusted bolts that require extra leverage to turn.
