The Slogging Spanner (30mm, Open End, CRV) is a heavy-duty hand tool designed for high-torque applications, particularly when working with large fasteners that require a lot of force to tighten or loosen. It features a 30mm open-end jaw, providing a solid grip on nuts or bolts. Made from chrome vanadium (CRV) steel, the spanner is both strong and durable, capable of withstanding the impact of a hammer or mallet (slogging) without damage. Ideal for industrial, automotive, and construction work, it is perfect for tasks involving tight or stubborn fasteners that need extra force.
