Screwdrivers are most broadly classified by their:
length |
|
torque |
|
width |
|
tip |
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).

What is a caliper used for?
transferring distances between objects |
|
ensuring that surfaces are level |
|
making perfectly vertical lines |
|
measuring thickness and irregular shapes |
Calipers are similar to micrometers in shape but instead of measuring distances, calipers are used to transfer distances between objects. An outside caliper is used to transfer outside dimensions while an inside caliper is used to transfer inside distances. A vernier caliper is an extremely precise caliper (down to \({1 \over 1000}\) inch) that allows measuring / transferring either inside or outside dimensions.
Which of the following is used in metal work for shaping metal?
claw hammer |
|
mallet |
|
rivet hammer |
|
ball peen hammer |
Ball peen hammers are most commonly used in automotive repair. They have rounded heads and are used to drive punches and chisels.
Which of the following is not an aspect of the mechanical advantage of pliers?
focus hand grip force |
|
change the direction of hand grip force |
|
amplify hand grip force |
|
provide precision for manipulating small objects |
Pliers are designed to provide a mechanical advantage, allowing the force of the hand's grip to be amplified and focused with precision. Pliers also allow finer control over objects that are too small to be manipulated by the fingers alone. The standard configuration is combination pliers which provide a fixed maximum jaw width. Other styles include adjustable joint pliers that allow selecting jaw width, needle nose pliers for holding small objects in tight spaces and locking pliers that will lock in place to hold or clamp objects together.
