A pipe wrench is a mechanical tightening tool used in machining, maintenance, and DIY projects to loosen or tighten bolts, nuts, and screws. By its design, this type of wrench is specifically made to rotate bolt heads or nuts that are set deep into a hole, thus unsuitable for flat wrenches. A pipe wrench has a cylindrical shape with an elongated part and a curved end, giving it an L-shaped appearance.
Pipe wrenches are equipped at both ends with female hexagonal shaped inputs and dimensions suitable for bolts of the same reference. It is a very practical wrench and ensures a good tightening of nuts. Similar to the ratchet wrench, the pipe wrench is available in several references for powerful tightening. Generally, these wrenches are made of galvanized steel, chrome-vanadium steel, or other metals strong enough to withstand significant forces of pressure. To meet the needs of professionals and industries, a wide range of hex key sets is offered for carrying out all operations of tightening, loosening, assembling, and disassembling. Some models of pipe wrenches have a visible hole on the bend of the wrench. Inserting a screwdriver or a metal rod into this hole allows for a greater force of pressure when turning the wrench during tightening or loosening. Silverline, KStools, and Stanley are among the reference brands for these tools.
