Screwdrivers are most broadly classified by their:
length |
|
width |
|
tip |
|
torque |
Screwdrivers come in many different handle, shaft, and tip configurations for use in a wide variety of applications. Screwdrivers are classified by their tip which is shaped to fit a corresponding screw head. Common tips are slotted (flat) and Phillips (x-shaped).
When cutting hard metals with a hacksaw you should choose a blade with __________ teeth per inch (TPI).

odd |
|

Which of the following nuts use a pin to lock the nut in place and prevent it from loosening?
slotted |
|
wing |
|
cotter |
|
lock |
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.
