You are ultimately responsible for your safety, so remember to __________.

A(n) __________ holds parts together while they are being assembled, drilled, or welded.

Technician A says wheel lug studs and lug nuts clamp the wheel assembly to the suspension system, and the weight of the vehicle tries to sheer the lug studs. Technician B says that cylinder head bolts must withstand the very high combustion pressures trying to push the head off the top of the engine block in order to prevent leaks past the head gasket. In this situation, the pressure is trying to stretch the head bolts, which means they are under tension. Who is correct?

Technician A says a ½" bolt does not mean that the bolt has a head that fits into a ½" socket. Technician B says that the distance across the outside diameter of the bolt’s threads measures ½" in diameter. Who is correct?

Technician A says that taps are used to make internal threads in drilled holes​. Technician B says threading dies are used to cut external threads on round work. 

Technician A says a stud has threads that are cut on each end.

Technician B says a stud always has different threads on each end​. Who is correct?

Which government agency is responcible for enforcing enviornmental issues in the workplace?

Technician A says a cordless drill is always used to drill holes before taping new threads. Technician B says when making new threads it is important to use plenty of anti-seize. Who is correct?

Which of the following fasteners will support the most load?

Which of the following tightening methods produces the most accurate preload force on a threaded fastener?

Technician A says a spring washer is used to prevent fasteners from loosening. Technician B say a serrated edge toothed washer prevent fasteners from loosening. Who is correct?

One of the most important mechanical properties of threaded fasteners is tensile strength, which indicates how strong the fastener is.

Threads both convert and amplify the rotational or twisting force used to tighten fasteners into clamping force

Threaded fasteners are a permanent method of fastening parts together.

Threaded inserts are high-quality internal thread repair kits which involve drilling damaged threads and installing an insert with original thread dimensions.

A variety of two-part epoxy materials and high strength and temperature metal putty should never be used to form the replacement threads.

Thread chasers or thread files are designed to remove debris and rust and straighten bent threads.

Thread damage can occur due to the following:

Fender washers are large outside diameter flat washers used to clamp soft materials such as mud flaps or inner fender panels.
