The Slogging Spanner 85mm Ring End CRV is a type of heavy-duty wrench designed for high-impact tasks where significant force is needed to tighten or loosen large fasteners. 85mm refers to the size of the wrench, specifically the opening of the ring end. It is designed for use with fasteners that have an 85mm diameter. Ring End: The wrench features a ring-shaped opening at one end, which fits around the head of a bolt or nut, providing a secure grip for turning. CRV stands for Chrome Vanadium, which is the material the spanner is made from. Chrome vanadium steel is known for its strength, durability, and resistance to wear and corrosion. It is commonly used in the construction of hand tools for heavy-duty applications. Slogging Spanner: A slogging spanner is designed to withstand high impact. It is typically used with a hammer or mallet to apply extra force to the fastener, making it ideal for applications where a standard wrench would not provide enough leverage, such as working with large bolts or in industrial settings. This tool is commonly used in construction, mechanical work, and industrial applications where large, tough fasteners need to be tightened or loosened with considerable force. The CRV material ensures the spanner can handle the impact without breaking or bending.
