Question

1. identify the common types of nuts used in a vehicle.
2. a(n) ___ washer prevents the bolt or nut from digging into the part.
3. a(n) ___ washer keeps a bolt or nut from loosening under stress and vibration.
4. ___ screws are similar to bolts, are threaded their full length, and are relatively small.
5. ___ screws are commonly used on plastic and sheet metal parts.

torquing bolts and nuts

1. define torque specifications.
2. ___ is a bolt - tightening method that requires the bolt to be tightened to a specific torque and then turned an additional number of degrees.
3. why is it important to use the proper bolt tightening sequence when torquing bolts on an engine?
4. which of the following is not a basic rule to follow when using a torque wrench? (a) pull only on the handle of the torque wrench. (b) use swivel joints whenever possible. (c) read the scale while looking straight down at it. (d) tighten bolts and nuts in four steps.

Explanation:

1. Vehicle nuts include various types like cap nuts, lock nuts etc. Without specific names for the depicted nuts, we can't precisely identify them by name, but they are common in automotive.
2. A flat washer prevents the bolt or nut from digging into the part as it distributes the load.
3. A lock washer keeps a bolt or nut from loosening under stress and vibration by creating friction.
4. Machine screws are similar to bolts, threaded their full - length and relatively small.
5. Sheet metal screws are commonly used on plastic and sheet metal parts.
6. Torque specifications define the amount of rotational force (twisting force) that should be applied to a bolt or nut during tightening to ensure proper assembly and prevent over - tightening or under - tightening.
7. Angle - tightening is a bolt - tightening method that requires the bolt to be tightened to a specific torque and then turned an additional number of degrees.
8. Using the proper bolt tightening sequence when torquing bolts on an engine is important to ensure even clamping force, prevent warping of engine components (like cylinder heads), and ensure a proper seal.
9. Using swivel joints whenever possible is not a basic rule when using a torque wrench. Pulling only on the handle, reading the scale straight - on, and tightening in steps are valid rules.

Answer:

1. No specific answer given for naming the nuts.
2. Flat washer
3. Lock washer
4. Machine screws
5. Sheet metal screws
6. The amount of rotational force to apply to a bolt or nut during tightening to ensure proper assembly and avoid over/under - tightening.
7. Angle - tightening
8. To ensure even clamping force, prevent warping of engine components and ensure a proper seal.
9. B. Use swivel joints whenever possible.
