Regardless of whether you are a DIYer or a professional plumber, a wrench is an inseparable part of your arsenal. When it comes to wrenches, there have numerous categories, one of the most common being a spud wrench.\n\n\n\nA spud wrench is an adjustable wrench, having a narrow spike as a handle, and can be used for lining up the holes for bolts while doing things like sink fitting, pipe fitting, etc. The bolts can then be set in place and tightened.\n\n\n\nThe word, \u2018spud\u2019 originates from the Irish culture who would call the knife they used to cut potatoes a spud. Due to the similarity between that knife and the handle of the spud wrench, the name caught on over time.\n\n\n\nA spud wrench was first introduced as the Maddock Spud by Thomas Maddock in the early 20th century. The design was bought by the Standard toilet company. Over the years, modifications were made to the original design to result in what we now refer to as a spud wrench.\n\n\n\nAnyhow, in our guide below, we have detailed everything you need to know about a spud wrench, including the method to use it, where to use and its various subcategories.\n\n\n\nSo, let\u2019s get started!\n\n\n\nHow to Use a Spud Wrench?\n\n\n\n\n\n\n\nUsing a spud wrench is fairly simple which allows the required job to go on smoothly.\n\n\n\nSo, firstly, the hole, where a bolt is to be inserted, is aligned using the spike. The process of alignment could include widening the hole or digging into it. A bolt is then, placed in the hole. Finally, the wrench is turned around to secure both the nut on one end and the washer on the other.\n\n\n\nWhat is a Spud Wrench Used for?\n\n\n\nA spud wrench is essentially an open-ended wrench that is used for tightening or loosening a variety of fasteners, including nuts and bolts.\n\n\n\nIt is mainly used for aligning holes in steel construction frames since it is quite a predicament to ensure the alignment of holes during the assembly process. Luckily, a spud wrench turns out to be just the perfect tool for the job.\n\n\n\nApart from that, a spud wrench is often used to loosen spud nuts found in the toilets as well as for the installation of water heaters, radiators, and other large devices.\n\n\n\nTypes of Spud Wrenches\n\n\n\nSpud wrenches come in three different types.\n\n\n\nIronworker\u2019s Spud Wrench \/ Construction WrenchPlumber\u2019s Spud WrenchRadiator Valve Spud Wrench\n\n\n\nIronworker\u2019s Spud Wrench \/ Construction Wrenches\n\n\n\nThe ironworker\u2019s spud wrench gets its name from the ironworkers who used this wrench while lining up large beams and girders to construct buildings. The fact that the ironworker\u2019s spud wrench worked with those beams and girders proves its durability and strength.\n\n\n\nIronworker\u2019s Spud Wrench \/ Construction wrenches can be sub-categorized into Adjustable Spud Wrench and Offset Spud Wrench.\n\n\n\nAdjustable Spud Wrench\n\n\n\nAlso known as a crescent spud wrench, the ability of this wrench\u2019s head to be adjusted to different sizes is what allows it stands out. Its head is also angled in a way as to help it in torque.\n\n\n\nIt has two jaws; one fixed and one moveable, meaning that only one adjustable spud wrench can be used to tighten or loosen numerous sizes of bolts and nuts.\n\n\n\nThe only drawback with an adjustable spud wrench is that it doesn\u2019t have a solid grip, unlike a fixed wrench.\n\n\n\nOffset Spud Wrench\n\n\n\nThis type of spud wrench has a curved head that allows for better torque during usage. In tight places, where a standard spud wrench is practically useless, an offset spud wrench comes in pretty handy.\n\n\n\nPlumber\u2019s Spud Wrench\n\n\n\n\n\n\n\nAlso known as a closet spud wrench, a plumber\u2019s spud wrench was originally crafted to work on pipes containing spuds, meaning that its use was mainly in the toilets with unique designs.\n\n\n\nOver the decades, with the introduction of new toilet designs, this tool\u2019s use has dropped significantly. However, when dealing with relatively older plumbing designs, it is often used by plumbers, pipe-fitters, and related professionals. They use it to work the bolts, collar, and other pieces of equipment concerned with the spud.\n\n\n\nA plumber\u2019s spud wrench can be sub-categorized into internal spud wrench, external spud wrench, and Adjustable Plumbing spud wrench.\n\n\n\nInternal spud wrench\n\n\n\nAn internal spud wrench is made up of a handle with a tool on either side that spreads outwards. Its unique design allows it to go inside a bolt and move it from within.\n\n\n\nJust as a screwdriver, as you turn the tool one way, it causes the bolt to fit while turning it the other way causes the bolt to retract.\n\n\n\nExternal spud wrench\n\n\n\nResembling a standard wrench, an external spud wrench has a handle on one side and an adjustable grip on the other. It is commonly used to clench pipes, large nuts, and whatnot, in order to either hold them in place or turn them such that they can be removed or attached.\n\n\n\nThe sleek design of this wrench allows you to access bolts and nuts in narrower spaces.\n\n\n\nAdjustable Plumbing spud wrench\n\n\n\nThis is again, a spud wrench that can be adjusted to fit a variety of different sized bolts and nuts. However, it doesn\u2019t have the firm grip of a standard wrench.\n\n\n\nRadiator Spud Wrench\n\n\n\nThis variant of spud wrench is particularly used on radiator valves \u2013 to either remove or replace them. It comes in various sizes to match the size of the radiator valve, which usually varies from 1\/2\u2019\u2019 to 2\u2019\u2019.\n\n\n\nSo, basically, a valve is attached to a radiator through a spud. The grooves of a radiator spud wrench get affixed to the nubs located in the interior of the spud. Then, you can use the wrench to either tighten or loosen the spud.\n\n\n\nDue to the exclusive nature of spuds found on the radiators, the usage of a radiator spud wrench is very limited. However, it is quite possible to use a few variants of a radiator spud wrench on the spuds that are similar to the ones located on the radiators.\n\n\n\nFrequently Asked Questions\n\n\n\n\n\n\n\nWhat is a Spud Wrench Made Of?\n\n\n\nA spud wrench is composed of alloy steel, which explains its durability and toughness.\n\n\n\nWhat is the Difference Between a Spud Wrench and a Pipe Wrench?\n\n\n\nA pipe wrench is normally bigger and sturdier than a spud wrench and is required for tightening and loosening pipes and other plumbing connections. On the other hand, a spud wrench works to tighten or remove small nuts and bolts.\n\n\n\nConclusion\n\n\n\nAll in all, a spud wrench is a fairly simple-to-use tool that comes in pretty handy to tighten or loosen all forms of fasteners, mainly bolts, and nuts. Also, using its pointy handle, you can align the holes, especially in heavier parts, so that a bolt can be secured conveniently.
