The TOLSEN 17056 is a 36 mm ring slogging wrench designed for heavy-duty tasks where standard wrenches cannot provide enough leverage. Made from high-strength steel, this tool is built to withstand the intense pressure of being struck with a sledgehammer, allowing you to loosen or tighten large, stubborn bolts and nuts that have become seized or over-tightened. Its specialized design makes it a reliable choice for professionals in mechanical workshops, auto maintenance, and construction, as well as for demanding DIY projects. The robust construction ensures that the force from the hammer is transferred efficiently to the fastener, providing the necessary impact to break through corrosion or extreme tension.
