Wrenches are used with threaded fasteners like bolts and nuts. A bolt has external threads while a nut has internal threads and this thread pattern combination allows them to lock together and act as fasteners. Nuts come in a variety of configurations including wing nuts which provide appendages that allow tightening and loosening by hand, slotted nuts that use a cotter pin to lock the nut in place and prevent it from loosening, and lock nuts that also prevent loosening via nylon in their threads. Threads are identified by pitch which is the number of threads per inch.

The joining material for a weld is called a welding or filler rod and is available in a variety of diameters and alloys for different welding tasks.

A miter box utlizes a back saw (a fine toothed saw with a rigid strip of steel opposite its blade edge) to make cuts in wood at a specified angle.

A joint created by soldering is not as strong as a weld and not as strong as the original metal.

A vise is a clamp that is anchored to a work station and designed to hold material in place while it is being operated upon.
