phillips |
|
slotted |
|
nut driver |
|
hex |
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).
An arc-welder creates heat using:
high voltage electricity |
|
natural gas |
|
oxyacetylene |
|
propane |
Welding is a high-temperature process that involves melting the base metals in the objects to be joined to fuse them together. A filler metal is used to provide additional material to make up a joint that, depending on the weld type, can be stronger than the base materials alone. Oxyacetylene welding is a welding process that uses a torch fueled with oxygen and acetylene gases. Electric-arc welding utlizes electric current in a safer welding process (it doesn't involve burning explosive gases) that enables a wide variety of specialized applications like stick, MIG (metal inert gas), and TIG (tungsten inert gas) welding.
When cutting hard metals with a hacksaw you should choose a blade with __________ teeth per inch (TPI).
low |
|
high |
|
odd |
|
even |
Blades with more and smaller teeth (high TPI) cut harder metals more effectively while blades with fewer and larger teeth (low TPI) cut softer metals more effectively.
This tool is a(n) __________.

|
punch |
|
awl |
|
screwdriver |
A punch is narrow and is used to drive objects like nails (pin punch) or for making guide marks for drilling (center punch) or patterns in wood or metal.
Which of the following is not an advantage of using a ratchet with a larger point-sized socket?
larger point sizes allow greater toque to be applied |
|
all of these are advantages of larger point sizes |
|
larger point sizes are stronger |
|
larger point sizes allow easier alignment |
A ratchet (or socket wrench) is a wrench that applies torque in only one direction with a handle that can be moved back and forth without losing contact with the fastener. A ratchet uses variable attachments called sockets which come in a variety of drive sizes based on the size of the opening that attaches to the ratchet. Sockets with the same drive size will vary in the shape (six-point, twelve-point) and size of the nut opening that attaches to the fastener being tightened or loosened. Smaller point sized sockets are stronger and can apply greater torque while larger point sizes allow easier alignment.
