The Slogging Spanner 80mm Ring End CRV is a heavy-duty wrench designed for high-impact applications, particularly where large amounts of force are required. The 80mm refers to the size of the ring end of the spanner, which is used for gripping bolts or nuts securely. The CRV (Chrome Vanadium) material indicates that the spanner is made from a strong, durable alloy, providing resistance to wear and corrosion. The slogging feature allows the spanner to withstand being struck with a hammer without damaging the tool, making it ideal for use in heavy-duty mechanical, construction, or industrial tasks.
