What is a Spud Wrench?

A spud wrench is a wrench with an adjustable or standard box wrench on one end and a tapered spike on the other. The spike can be used to line up bolt holes when installing pipe fittings, doing automotive work or—in the case of iron workers—for lining up bolt holes in girders and beams. Some have offset handles for better leverage or access to parts. There are other types of wrenches that carry the moniker “spud”, so make sure you know what you’re buying before plunking down your dough.

And yes, we know there is another tool called a “closet spud wrench” that is used in close quarters for closet spuds, basket strainers nuts and spud nuts.
