The primary difference between a claw and a ball-peen hammer is which of the following?

59% Answer Correctly

	their non-striking end
	their size
	their handle shape
	their striking end

Solution

The most common striking tool is the hammer and the most common variety of hammer is the claw hammer. The claw hammer has two ends, one to drive nails and one to remove nails. Ball-peen hammers replace the claw with a rounded end that's used to round off the edges of metal pins and make gaskets.

Which of the following nuts prevent loosening via nylon in their threads?

63% Answer Correctly

	cotter
	slotted
	wing
	lock

Solution

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.

The primary difference between a standard level and a bullseye level is which of the following?

55% Answer Correctly

	a standard level has only one bubble to center
	a bullseye level has only one bubble to center
	a bullseye level can measure across two dimensions
	a standard level can measure across two dimensions

Solution

Levels utlize a fluid-filled tube containing a bubble that is centered when the surface is horizontal (level) or vertical (plumb) along the direction of the tube. While a standard level can measure along a single dimension, a bullseye level is circular and can indicate the levelness of a two dimensional plane.

Which of the following is not an advantage of using a ratchet with a larger point-sized socket?

34% Answer Correctly

	all of these are advantages of larger point sizes
	larger point sizes are stronger
	larger point sizes allow greater toque to be applied
	larger point sizes allow easier alignment

Solution

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.

Which of the following determines whether a socket can be used with a particular ratchet?

49% Answer Correctly

	the drive size
	the drive circumference
	the socket size
	the point size
